Chapter i: What is a starter solenoid
[/mk_fancy_title][vc_column_text css=".vc_custom_1512967728785{margin-lesser: 0px !important;}"]
What is a Starter Solenoid
A starter solenoid is a combination of solenoid and switches (Total name: Starter Solenoid Switch). It is one of the main components of the car starter (Motor, Starter Bendix Bulldoze, Starter Solenoid)
As we all know, the starting of the engine requires external support, and the car starter is playing this role. In general, the starter uses iii components to attain the entire starting process.
- The motor receives electric current from the battery and make the starter bulldoze gear generate mechanical motion;
- The Bendix drive engages the pinion gear into the engine flywheel and disengages automatically subsequently the engine beginning.
- And the starter's on/off function is controlled past the starter solenoid.
Starter Solenoid Functions
Starter Solenoid has ii functions:
ane. To command the showtime circuit on / off (Connect the bombardment to the starter)
2. Drive the starter pinion engaging in the flywheel ring gear.
Office 1
When turn on the ignition switch and the starter circuit is turned on, the electrical current flows to Starter Solenoid and create the electromagnetic force.
The electromagnetic forcefulness of the solenoid switch sucks the movable iron core in the Starter Solenoid to contact the 2 terminals, one of which connect to the positive pole of the battery and the other last to the starter.
Function two
The electric electric current divides into two streams flowing through the Starter Solenoid:
A ). A stream flow through the sucking coil, generating a magnetic forcefulness to sucks the movable iron core and move the fork backward and then that the starter pinion can engage the engine flywheel.
B). The another stream flows through the holding coil, creating a magnetic forcefulness to keep the core in the post-pulling position until the starting consummate.
Where is the starter solenoid
In a automobile starter motor with Starter Solenoid, the Starter Solenoid is unremarkably mounted straight on the to of starter motor. So where is the starter motor, where is the starter solenoid.
Starter Solenoid Operation
The whole process of starter solenoid switch can be divided into 3 stages: Sucking, belongings, render.
(1) Sucking
When the ignition switch turns to the Kickoff position, the battery current flows to the sucking coil and concord ringlet.
The electric current then flows from the sucking whorl to the armature whorl thus make the coil rotated at a low speed.
In this way, the movable cadre of the solenoid switch sucks into the cadre.
Through the sucking performance, the starter bulldoze pinion volition be pushed out and engaged with the band gear. As well, the contact plate closes the main contact point.
(2) Property
When the main contact point of the plate close, no current flows through the sucking roll. So, the magnetic field roll and the armature coil can get the electric current directly from the bombardment.
The armature coil then begins to rotate at high speed, and the engine starts.
Because no current flows through the sucking gyre, so the moving atomic number 26 core can only agree the whorl in a fixed position by the magnetic force.
(3) Return
When the ignition switch turns from First to ON, the current flows from the primary contact side to the holding curlicue via the sucking scroll.
In this point, since the magnetic force formed by the sucking coil and the holding coil neutralize each other, they lose the force to hold the movable core.
Thus, the plunger is pulled back by the return spring forcefulness, and the contact plate is disconnected, the starter stops.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1498088701961{background-colour: #f2f2f2 !important;}"][vc_column][mk_fancy_title colour="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+1" font_type="google" align="heart"]
Chapter ii: Starter Solenoid Troubleshooting
[/mk_fancy_title][vc_column_text css=".vc_custom_1532476334345{margin-bottom: 0px !of import;}"]
Starter Solenoid Issues
The starter solenoid has 4 common bug:
1) The suction fails occasionally, or works in engine cooling merely and fails in engine warming up.
2) When starting up, the starter solenoid can not reset. Release the starting time button, the starter remains in operation and but stops when power off.
3) The elastic force of the return spring weakens afterwards repeated use, resulting in that the drive gear of one-way clutch cannot exist restored timely, but driven and reversely dragged past the flywheel band gear.
4) When the starter starts, information technology will brand a periodic noise from the starter solenoid, but the starter does non rotate.
Symptoms of a bad starter solenoid
A multimeter is needed to test and verify the bug of the starter solenoid, but before the testing, the following table can be used to determine whether the starter solenoid works:
[mk_table]
| Fault symptom | Possible reasons for the failure |
| The starter solenoid make the clicking dissonance continuously | The starter solenoid belongings coil proceed holding or the contacts sealing-off |
| Subsequently switching on the starter, the starter solenoid makes the clicking dissonance, slightly moves but does not rotate. | a.The connection between the solenoid and starter is defective b.Starter solenoid is broken |
| The showtime button has disengaged, and the bulldoze gear has returned, only the starter continues to rotate. | The starter solenoid contact burn-out |
| The kickoff push button is disengaged, the starter continues to rotate, but the drive gear can not reverse. | The starter solenoid has contact burnt, or the movable atomic number 26 core and return leap cannot move due to no enough elastic force(poor quality) |
[/mk_table]
Exam a starter solenoid with a multimeter
Set the multimeter punch to continuity way, connect the multimeter probes to the solenoid terminal post( the one used to connect to the motor body) and the solenoid shell.
If there is a resistance, then the holding coil is adept.
If the resistance is zero, and then the circuit might be shorted.
If the resistance is infinite, so the circuit could be broken. If there is a brusk circuit or broken circuit, you should replace the starter solenoid.
If your multimeter has the continuity style, it will be even easier to figure out your starter solenoid condition past testing the continuity of each connection.
Set the continuity mode, cheque the continuity between Final S and M. If there is a continuity,(The screen displays a value of cypher (or most null), and the multimeter beeps. ) replace the solenoid.
Ready the continuity mode, check the continuity between Last South and the machine body. If at that place is no continuity(The screen will display 1 or OL (open up loop).), replace the solenoid.
Fix the continuity mode, check the continuity between Final M and B. If at that place is continuity(The screen displays a value of zero (or near zero), and the multimeter beeps. ), replace the solenoid.
Starter Solenoid No-load Examination
1.Starter Solenoid Sucking Coil Test
Disengage the outer atomic number 82 of the starter field winding (Terminal C, see Fig. below), connect the positive pole of the motorcar battery to Terminal 50, and negative pole to the starter Terminal C and the shell.
At this point, the drive gear should motion forward.
If not, the solenoid sucking coil is very likely damaged.
2. Starter Solenoid Holding Coil Exam
If the drive gear in the previous test can move forrard, then disconnect the Terminal C and connect it to the wire of the battery terminal negative, as shown in Figure, the bulldoze gear should remain outside.
If the drive gear reverses, information technology indicates that the solenoid holding coil is damaged.
iii. Starter Solenoid Bound Examination
Based on the above test, disengage the beat wire connected to the bombardment concluding negative, as shown in Figure below.
Normally, when the battery terminal negative is disengaged, the bulldoze gear should reverse rapidly.
If the drive gear cannot reverse, it indicates that the solenoid return spring is damaged.
Troubleshooting/exam a starter solenoid with a screwdriver
A screwdriver can also exist used to test the starter solenoid if you don't have a multimeter.
And it too is a quick and easy method to diagnose the solenoid starter solenoid clicking racket problems.
Connect the 2 concluding posts of the starter solenoid with a screwdriver, if the starter does not rotate, the malfunction lies in the starter. If the starter functions well, the malfunction lies in the solenoid switch and is often caused by the ablation of the starter solenoid contacts.
Also, yous can try to shake the connecting line of the auto battery and the starter, if the starter functions well, then the starting excursion might be in a poor contact. If and so, you should check the loftier temperature or the sparking parts in the starting system circuit.
Bypass Starter Solenoid: Start machine with a bad starter solenoid
Sometimes the starter could not rotate, or the rotate speed is low after switch on (brightness of the headlamp is fine), and when the starter terminate to rotate, there is foreign chugging noise near the starter motor, it indicated that the starter solenoid switch got a problem.
If the solenoid switch got some issues when you are driving, you could use a pb wire to make an emergency starting circuit.
Just connect the battery final anode and terminal B of the starter by a pb wire.
After the circuit is well connected, plough the ignition switch to first position, the starter would work and start the auto engine.
Recollect to disconnect the wire immediately once the automobile starts, and discover the closest repair shop as soon as possible to ready the starter solenoid problem.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1500084984306{background-color: #ffffff !important;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+I" font_type="google" align="heart"]
Chapter 3: Starter Solenoid Wiring Diagram
[/mk_fancy_title][vc_column_text css=".vc_custom_1513217848962{margin-bottom: 0px !important;}"]
Starting Organization Wiring Diagram
Firstly, let's check the of the starting arrangement circuit, the wiring diagram as shown in the Fig. beneath. At that place is a connection between the starter, the car bombardment, and the ignition switch. The working circuit of the starter can be activated after the ignition switch is on.
The starting system wiring diagram is every bit shown in below image.
While the ignition switch is non turned to the start position, the starter solenoid will non connect to the showtime excursion, and the starting gear is separated from the flywheel. Once the ignition switch is turned to the start position, the magnetic coil circuit volition connect to the circuitry.
The sucking coil circuit is as below:
Car battery anode (+) > fuse > ignition switch (start position) > solenoid final 50 > sucking curl > concluding c of the solenoid switch > field coil > positive brush > armature scroll > negative castor > ground wire > storage bombardment cathode(-)
The belongings coil excursion is every bit below:
Storage battery anode > fuse > ignition switch (start position) > solenoid concluding 50 > holding coil >footing wire > auto bombardment cathode (-)
After current passes through the sucking ringlet and belongings coil, as the current direction is identical, the magnetic field is superimposed, the iron core will be sucked in.
Then, the atomic number 26 cadre will drive the starter drive clutch to move astern so that the starter gear can mesh with the engine flywheel.
While the starter gear almost completes the meshing (with the flywheel), the iron cadre volition move forward to a item position, to make the contact panel touch with the contacts. Thus the starter solenoid switch will plough on.
After the starter gear has completely meshed with the flywheel, the iron cadre volition motility forwards to an extreme position, and the solenoid switch volition exist pressed tightly and connect to the automobile starter. In the end, the starter motor rotates, and the engine starts driven by starter drive.
The starter motor circuit is as below:
car battery anode(+) > solenoid switch last 30 > contact panel > solenoid switch terminal C > field coil > positive brush > armature coil > negative brush > ground wire > automobile battery cathode(-)
When the terminal thirty & C of starter motor are continued, the pull-in roll will short out. The position of the fe core after suction can be maintained merely by the magnetic forcefulness of the holding curlicue.
When the ignition switch turns back to On position afterward cranking the engine, the starting excursion volition plough off, and the starter will terminate rotating. The starter drive gear returns past the leap, the starter bulldoze gear, will separate with the engine flywheel.
Starter Solenoid Wiring Diagram
Non every car bear the starter relay in starting arrangement, and the starter solenoid wiring diagram can be learned by with or without starter relay blazon.
1. Starter Solenoid Wiring Diagram – Without Starting Relay Type
The starting system circuit without starter relay gear up in is shown in Fig. below.
After turn on the ignition switch, terminal 50 of the ignition switch is connected to the B8 node of the central circuit board via the red or black wiring, then to the solenoid terminal 50 of the starter via the C18 node of the fundamental circuit board. The battery anode (+) is connected to last 30 of the starter via the black wiring.
When turning the ignition switch to the get-go position, the current direction is as below:
Auto battery anode(+), ignition switch start gear, last 50, sucking coil, last C, field winding, armature winding, footing wire, car bombardment cathode(-)
Meanwhile, the current direction that passes through the holding coil is as below:
machine battery anode(+), ignition switch commencement gear, terminal 50, belongings coil, bonding, car battery cathode. (The working process has been introduced before in Starting Organization Wiring Diagram)
two. Starter Solenoid Wiring Diagram – Without Starter Relay Type
To protect the ignition switch, lots of modernistic cars apply the starter relay to control the starter solenoid. The starter solenoid wiring diagram with starter relay shows in the following Fig.
When the ignition switch has not turned to the start gear, no current will passes through the relay roll, and the starter relay contacts are open. Also, the starter solenoid is not energized, and the drive gear is separated from the flywheel ring gear.
After turning the ignition switch to the start position, the circuit of the starter relay coil will be conductive, and the electric current direction is as below:
Afterward turning the ignition switch to the offset position, the excursion of the starter relay coil volition be conductive, and the electric current management is as below: automobile battery anode > ignition switch concluding 1 > ignition switch terminal 3 > starter relay last (The i use to connect to ignition switch) > coil footing wire > motorcar battery cathode.
After the starter solenoid coil is conductive, the starter relay contacts will be airtight, and connect to the sucking coil and holding coil circuit. (The working procedure has been introduced before in Starting System Wiring Diagram)
In the starting system with an electronic-controlled engine, the ground last of the starter relay roll is connected to the neutral position of the ignition switch (cars with automatic manual tin can only first the engine in the position P & N ) or the interlock switch of the clutch, as shown in the left Fig.[/vc_column_text][vc_column_text]
Starter Solenoid Wiring
How to wire a starter
Most of the solenoids are installed direct on the starter, and they are closely related to each other. Hence, before learning how to wire a starter solenoid, the starter's wiring should be studied.
A four-last starter has two thick terminals and two thin ones, it might be a little confused to detect out which is which if yous are not a professional.
The 2 thick terminals post
One of the 2 thick terminals posts is connected to the automobile bombardment, and the other is continued to the field winding within the starter via the conducting plate on the vanquish of the starter.
Therefore, the thick terminal post with conducting plate shall be continued to the field winding, while thick terminal postal service without conducting plate shall be continued to the car bombardment.
Only if the conducting plate is not at that place, how to distinguish between the 2 thick terminals, and so?
Actually, the sucking curlicue inside the starter solenoid switch is connected to one of the thick terminals via the welding spot, and then to the field winding, the armature winding and finally to the negative brush bonding. Therefore, the thick final with one thread end should be connected to the field winding, while thick concluding without thread end should be connected to the car battery.
The 2 thin terminals mail service
The concluding post with ii thread ends (the sucking coil and holding scroll are welded together via the welding spot and then continued to the sparse terminal) is pull-in last, (namely, the solenoid terminal)
The other thin last post is direct connected to the shrapnel inside the motor, so thin terminal without thread end is the ignition switch last.
How to wire a starter solenoid
There are 3 terminals on the solenoid insulating cover (also called starter solenoid cap), those are, concluding B (or 30), final M (or C) and start terminal S (or 50).
Sometimes, there are 4 terminals on the solenoid cap, and those are: concluding B (or 30), last M (or C), offset last S (or fifty) and ignition terminal R (or 15a), as shown in Fig below.
Concluding B and Terminal K are usually copper bolts with a thickness of 8mm or 10mm, the one with lug plate is final M, which is the power supply terminal of the motor field winding; the other one is concluding 8, which is the power line terminal of the car battery.
Starting time terminal Southward and ignition terminal R are usually iron bolts with a thickness of 4mm or 5mm, the 1 with lug plate is starting concluding S, the electric wire of which is led to the starter relay; the other i is ignition last R, the electric wire of which is led to the boosted resistance of the ignition scroll. The solenoid shell is as well an invisible terminal 31(the ground wire).
The switch part of starter solenoid is composed of a main contact plate and contacts. The primary contact plate is fixed to the front end of the movable fe core push button rod, and the two contacts are respectively integrated with the double-screw commodities of the connecting lead terminal C and the power supply terminal 30.
Near the switch contacts, there is an additional resistance short circuit switch fabricated of a small copper sheet, which is continued to the terminal 15a.
The inner structure of the solenoid is shown in the left Fig.[/vc_column_text][/vc_column][/vc_row][vc_row css=".vc_custom_1500084993763{background-color: #f2f2f2 !important;}"][vc_column][mk_fancy_title color="#000000″ size="41″ font_weight="900″ margin_top="20″ font_family="Patua+One" font_type="google" marshal="center"]
Chapter 4: How to replace a starter solenoid
[/mk_fancy_title][vc_column_text css=".vc_custom_1512967499990{margin-bottom: 0px !important;}"]
Starter Solenoid Replacement
If you desire to replace your starter solenoid, you take to take out the starter motor from your vehicle start. The location of the starter motor can be differed by car models, the following instruction is the regular way to supervene upon a starter solenoid. The stride 1-vii is about removing a starter motor and step eight-11 near replace a starter solenoid.
Step 1. Disconnect the motorcar bombardment negative cable
Pace ii. Lift the vehicle if the starter motor is under the auto.
Step iii. Remove the nut in the starter solenoid terminal.
Step 4. Dismount the terminal of the cable of the car battery anode from the starter.
Stride 5. Remove the nut in the starter solenoid terminal S.
Stride vi. Remove the retaining bolts in the starter.
Step 7. Take out the starter.
Stride 8. Unscrew the retaining nut of the solenoid concluding, as shown in the pictures below.
Footstep 9. Unscrew the two basics that fix the solenoid to the beat of the starter Bendix drive and remove the solenoid. Equally shown in the following motion-picture show.
Step 10. Install the new starter solenoid according to the reverse process of removing the solenoid.
As shown in the above figure, hook the plunger hook to the starter fork, then use retaining bolts to install the starter solenoid to the starter beat out. Note and marking the installation direction of the starter solenoid before the disassembly, if install in the opposite position, the starter will not operate. Connect the motor lead, install and fix with a nut.
Step eleven. Starter Solenoid Retesting
After the solenoid is installed, connect the respective circuit. The no-load test can be carried out on the automobile battery to verify the maintenance event of the starter. The starter tin can be installed on the vehicle after it operates well in the no-load test. The retest way is equally same as the Starter Solenoid No-load Test in Chapter 2.
Stride 12. Install the starter motor according to the reverse process of removing the starter motor (Step 7-ane).
Caution: 5 Tips for replacing a starter solenoid
one. If you lose the retaining bolt of the starter, y'all should be careful with the length of the new bolt, in example that over-long bolt bursts the coil erstwhile (some models of solenoids will non accept this fault) and induces ground loop. Also, remember to utilise a spring washer when installing the bolt.
2. The current of the starter is large in operating and terminal B and terminal M will overheat because of that. So retrieve to use a spanner to tighten the terminal nuts while yous are maintaining your starter solenoid.
3. To avoid the bad contact, the lead wire of the terminal B and concluding One thousand should be clamped with 2 flat washers.
four. The two retaining bolts in the solenoid cover contacts are quite piece of cake to loose due to the starter vibrating, so they should be tightened whenever maintaining the starter.
5. To reduce the resistance of the movable fe core at work, a thin layer of engine oil should be coated on the surface of the cadre (anti-freezing engine oil should be used in wintertime).
Starter Solenoid Price
The starter solenoid prices are differed by different models, quality, and manufacturers. Meanwhile, larger solenoids (such every bit the Heavy Duty series starter solenoid) tend to be more expensive than smaller ones.
The best is definitely the OEM starter solenoid, and solenoids in the aftermarket are relatively cheaper.
When I was writing this guide, I establish a quite interesting volume, and at that place are many electrical accessories' prices recorded in the book. Part of the starter solenoid prices are every bit follows:

Chapter v: How to repair a starter solenoid
[/mk_fancy_title][vc_column_text css=".vc_custom_1512967612006{margin-bottom: 0px !important;}"]Near of the cleaved starter solenoid switches are repairable, but the labor charge of repairing a solenoid switch tends to exist higher than the solenoid switch itself, the repair shops are reluctant to repair the switches, instead of direct replacement is adopted.
We do not recommend non-professionals repair the switches by themselves. The following content is for reference only to those with certain experience. Non-professionals shall seek assistance from the local mechanic.
Starter Solenoid Disassemble
1.Pull out the movable fe cadre and spring from the rear terminate.
ii.Seal off the soldering tin at the connexion strap of the solenoid box with soldering iron, and then that the solenoid curl joint can trip out.
3.Unscrew the two retaining bolts of the switch cap, split up the starter solenoid cap from the solenoid housing, and pull the solenoid beam assembly parts out from the housing(solenoid shell).
Basic Starter Solenoid Repair
ane. Starter Solenoid Stuck Issue
The movable iron core should exist able to move smoothly. If not, you lot should find the trouble(s) that cause the stuck and ready it. Replace the leap if it's not in good condition. In virtually cases, the stuck issue is caused by the bad spring.
two. Starter Solenoid Contacts & Contact Plate burn-out
If the solenoid contacts are non fire-out very severely, then just use the sandpaper to smooth the surface of the solenoid contacts & contact plate.
If the surface is burn-out severity, y'all should open the solenoid cap, take out the contacts & contact plate, and file the contacts or add together the flat washer(s) till ii contacts are in aforementioned height.(The heights of the two contacts in the switch cap should be consequent)
3. Thread impairment of B/M terminal bolts
The terminals usually adopt M8 or M10 copper bolts. The traditional repair method is to dismantle the starter and starter solenoid from the vehicle, disassemble the solenoid, unscrew the terminal commodities, and use the threading die to rethread the last bolts.
Starter Solenoid Advanced Test
1.Starter solenoid scroll inspection:
Apply the R1(Resistance) scale of the multimeter to measure out the resistance of the pull-in whorl and the holding curl of the solenoid, and the resistance value shall be same with the starter solenoid specification.
If the resistance R=∞, the coil is asunder.
If the resistance is lower than the specified value, the coil has a fault of turn-to-plow brusk circuit.
(2) Starter Solenoid Working Performance Inspection:
a. Inspection of pull-in and drop-away voltage of solenoid: When inspecting, carry out wiring co-ordinate to the circuit shown in the correct Effigy.
Firstly plow on the switch, gradually increment the voltage, when the multimeter (resistance scale) indicates a resistance of zero, the indicated value of voltmeter 5 is the pull-in voltage of the switch.
Then gradually reduce the voltage indicated value, when the multimeter indicates a resistance of infinite, the indicated value of the voltmeter is the dropout voltage of the switch.
The pull-in voltage shall not exceed 75% of the nominal voltage, and the dropout voltage shall not exceed 40% of the nominal voltage.
b. The ignition coil additional resistance short-circuit switch inspection:
The testing circuit for the brusk-excursion switch is shown in Fig.ii-28. When turning on the switch, the indicator light in the circuit should exist brightened upward.
c. Starter Solenoid Outage performance Inspection:
When the starter drive gear is stationary and stays in the engaged position, cut off the solenoid ability supply. At this time, the master contact of the solenoid shall exist able to be interrupted quickly.
Based on the inspections higher up, solenoids with poor or unqualified performance should be repaired or replaced.
Starter Solenoid Whorl Rewinding
(one) Seal off the soldering tin on the connection strap of the switch cap and remove the switch cap.
(2) Clamp the switch housing on the demote spiral, unclench the riveting border of the switch with a screwdriver, and take out the whorl assembly.
(3) Dismantle the burned-out scroll (if you lot do not have the specific data, you should record the coil diameters, the number of turns and winding management of the old roll conductor).
Check the roll frame and the insulating pressing plate; if there is damage, you should repair information technology according to the original shape.
(4) When rewinding the coil, the bore, the number of turns and the winding direction of the wire should exist identical to the original ones.
In full general, the holding gyre (thin) is in the inner layer, and the pull-in coil (thick) is in the outer layer, the two coils have the aforementioned winding direction, and fish newspaper should be used to carve up the coils and to separate the curl frame and the housing.
(5) The positions of the four outgoing thread terminate on the two coils shall be distributed every bit the right figure(a).
Insulation tube shall be sheathed on the ends to prevent the insulation varnish of the wires from wearing out.
(6) Put the felt, curl assembly and iron plate in the switch housing and rivet them properly. Then twist the ends ane and 2 of the ii coils together, and weld starting cease 4 of the thin coil on the iron plate (see right prototype b).
(7) Assembling the contact plate and the switch cap, put out the end 1 and two of the coils from the connection strap hole of the solenoid terminal and weld firmly. Pulling out the starting cease 3 of the thick ringlet from the strap hole of the fixed contact plate and weld firmly (see right epitome c).
