Starter Motor
An electric motor that cranks the engine to begin combustion.
The starter motor engages with the flywheel when the ignition key is turned. Powered by the battery, it spins the engine just long enough for combustion to start. Modern systems use solenoids for reliable engagement. Faulty starters cause clicking sounds or no-crank conditions. Keeping battery terminals tight and corrosion-free helps prevent starter failure. Efficient starters ensure consistent ignition, especially in cold climates.
