A starter is an electrical motor that is connected to the battery. The job of a starter is to set the engine (pistons, crankshaft, etc.) in motion when you turn the ignition switch on. Once the engine starts and is in motion, the job of starter is done. If the starter goes bad, the engine will not crank properly when you turn the ignition key on or may not crank at all.
