Starter motors are composed of several parts, including an electric motor, a starter solenoid, a starter drive, and a starter gear.
The electric motor is responsible for providing the initial torque that turns the engine crankshaft.
The starter solenoid is an electromagnetic switch that engages the motor with the starter drive and starter gear to spin the engine crankshaft.
The starter drive is a gear that is engaged when the solenoid is activated and drives the starter gear, which is the gear that turns the crankshaft to start the engine.
What are the signs of a failing starter motor?
1. Clicking noise when turning the key in the ignition.
2. Slow cranking when you turn the key.
3. Slow cranking or no cranking when attempting to start the vehicle.
4. Dim headlights or interior lights.
5. Dashboard lights that flicker or fail to turn on.
6. A burning smell coming from the starter motor.
7. The vehicle failing to start even after multiple attempts.
