How do you know if your starter solenoid is bad?


Quick Answer

It is easy to tell a starter solenoid is going bad because the engine makes no noise when turning the key in the ignition. The solenoid is a device that charges and directs current through the starter, meaning a lack of response requires replacing that part. The solenoid is mostly present only in Ford vehicles.

Full Answer

The starter solenoid directs power through the engine and helps reinforce the charge in a starter component. Insufficient flow of electricity results in a lack of response from the engine, causing no sound or response when users try to start a car or truck. As the solenoid goes bad, drivers notice that there is an increasing reluctance from the engine to turn over. Subsequent tries show the car or truck makes a loud clunking or banging noise but does not start.

The solenoid is a mounted above the starter in a car and pulls charge from the device as energy is channeled through it. A bad starter solenoid does not hold or feed the charge back into a starter and does not allow the engine to run. This also happens when the grounding component of a solenoid is insufficient, causing too much charge to pool in the device and making it unsafe to allow power to continue to flow.
