What Does This Starter Motor Do?
An electric motor that cranks the engine during the start cycle by engaging the flywheel ring gear with a pinion gear. Draws a high current from the battery for a short burst to turn the engine over until combustion begins.

- A single click or series of clicks when the ignition key is turned but the engine does not crank
- Slow or laboured engine cranking, especially in cold conditions
- Starter motor spinning but not engaging the flywheel (grinding noise)
- No response at all when the ignition key is turned to start
