A starter solenoid is an electrical component that is used to engage the starter motor on a vehicle. When the ignition key is turned to the “start” position, the starter solenoid receives power from the battery and sends it to the starter motor. This causes the starter motor to turn the engine over, which starts the vehicle.
Starter solenoids can fail over time, which can prevent the vehicle from starting. There are a few different ways to test a starter solenoid to see if it is working properly. One way is to use a multimeter to check for voltage at the solenoid terminals. Another way is to listen for a clicking sound when the ignition key is turned to the “start” position. If you do not hear a clicking sound, it is possible that the starter solenoid is not working properly.
