Tips: How to tell if there is a problem with the car starter relay or the starter motor?

To tell if there is a problem with the auto starter relay or the starter motor, you can refer to the following steps:

Listen to the sound: When starting the car, if you hear a "click" sound but the engine does not turn, there may be a problem with the automotive starter relay. If there is no sound or only a slight clicking sound, it may be a problem with the starter motor.
Check the battery: Make sure the battery is fully charged. If the battery is low, it may cause both the engine starter relay and the starter motor to not work properly.
Voltage test: Use a multimeter to test the voltage of the starter relay and the starter motor. If the starter relay receives voltage but the starter motor does not turn, the problem may be in the starter motor. If the starter relay does not receive voltage, there may be a problem with the relay itself or the circuit.
Check the connection wires: Check whether the connection wires between the battery, the starter relay, and the starter motor are loose or corroded.
Replace the relay: Try replacing the starter relay to see if the problem is solved. If the problem persists after the replacement, it may be a problem with the starter motor.
