A starter motor solenoid is a necessary a part of any car. It’s liable for partaking the starter motor with the flywheel, permitting the engine to start out. If the solenoid is just not working correctly, the starter motor will be unable to interact and the engine won’t begin. There are a number of easy steps you may take to check a starter motor solenoid and decide whether it is working correctly.
First, you’ll need to disconnect the unfavorable battery terminal and find the starter motor. The starter motor is usually situated on the entrance of the engine, close to the underside. Upon getting situated the starter motor, you’ll need to determine the solenoid. The solenoid is normally a small, cylindrical machine situated on the facet of the starter motor. It can have two terminals, considered one of which shall be linked to the battery and the opposite to the starter motor.
Subsequent, you’ll need to make use of a multimeter to check the solenoid. Set the multimeter to the DC voltage setting and join the optimistic result in the terminal on the solenoid that’s linked to the battery. Join the unfavorable result in the terminal on the solenoid that’s linked to the starter motor. If the solenoid is working correctly, the multimeter will learn 12 volts. If the solenoid is just not working correctly, the multimeter will learn 0 volts.
Finding the Starter Motor Solenoid
The starter motor solenoid is a crucial element of your car’s beginning system. It is liable for sending electrical present to the starter motor, which in flip engages the engine’s flywheel and cranks the engine.
For those who’re experiencing issues beginning your car, it is doable that the starter motor solenoid is defective. To check the solenoid, you will first must find it. Here is a step-by-step information:

Find the starter motor solenoid. It’s normally mounted on the starter motor and has two massive terminals.
3.
Join the check gentle to the optimistic battery terminal.
4.
Contact the opposite finish of the check gentle to the “S” terminal on the solenoid.
5.
Have somebody flip the important thing to the “begin” place.
Outcomes
If the check gentle illuminates, it implies that the solenoid is receiving energy. If the check gentle doesn’t illuminate, it implies that the solenoid is just not receiving energy.
If the solenoid is receiving energy, the following step is to test whether it is functioning correctly. To do that, you’ll need to:
1.
Disconnect the check gentle from the “S” terminal.
2.
Join the check gentle to the “I” terminal on the solenoid.
3.
Have somebody flip the important thing to the “begin” place once more.
If the check gentle illuminates, it implies that the solenoid is functioning correctly. If the check gentle doesn’t illuminate, it implies that the solenoid is just not functioning correctly and must be changed.
Checking the Solenoid’s Coil Resistance
Now, let’s delve into the steps for checking the solenoid’s coil resistance:

-
Find the starter motor solenoid
Establish the solenoid, which is usually a cylindrical element hooked up to the starter motor. It usually has two or three terminals and should have a lever or plunger.
-
Establish the coil terminals
Look at the solenoid to find the 2 terminals linked to the coil. These terminals are liable for supplying energy to the coil.
-
Arrange the multimeter
Configure your multimeter to the ohms setting, normally labeled with the Greek letter Omega (Ω). Make sure the probes are firmly hooked up and correctly calibrated.
-
Join the probes to the coil terminals
Contact the probes to every of the coil terminals. Guarantee good contact between the probes and the terminals to acquire an correct studying.
-
Interpret the studying
The multimeter ought to show a resistance worth in ohms. A typical resistance vary for a starter motor solenoid coil is between 0.5 and a pair of ohms. If the resistance is outdoors this vary, the coil could also be defective and require alternative.
Changing the Starter Motor Solenoid

2. Find the starter motor solenoid, which is normally mounted on the starter motor.
3. Disconnect {the electrical} connectors from the solenoid.
4. Take away the bolts that maintain the solenoid in place.
5. Pull the solenoid straight off the starter motor.
6. Examine the solenoid for harm or corrosion. If the solenoid is broken, it’ll should be changed.
7. Set up the brand new solenoid on the starter motor.
8. Tighten the bolts that maintain the solenoid in place.
9. Join {the electrical} connectors to the solenoid.
10. Reconnect the unfavorable battery terminal.
11. Take a look at the starter motor to ensure it’s working correctly.
Troubleshooting a Starter Motor Solenoid
In case your starter motor is just not working, the solenoid could also be the issue. Listed here are some troubleshooting suggestions:
1. Verify {the electrical} connections to the solenoid. Be certain they’re clear and tight.
2. Take a look at the solenoid with a multimeter. The solenoid ought to have continuity between the 2 massive terminals.
3. If the solenoid is just not working, it might should be changed.
