In a cranking system, you can divide your symptoms into one of three possible troubleshooting categories: Slow Crank: The starter will crank, however, the engine RPM is slow to start the vehicle.

How does a positive engagement starter motor work?

Positive-engagement starters use the shunt coil windings of the starter motor to engage the starter drive. The high starting current is controlled by a starter solenoid mounted close to the battery. When the solenoid contacts are closed, current flows through a drive coil.

How does a cranking motor start a car?

As soon as the starter drive pinion gear contacts the ring gear, a contact arm on the pole shoe opens a set of normally closed grounding contacts. With the return to ground circuit opened, all the starter current flows through the remaining three field coils and through the brushes to the armature. The starter motor then begins to rotate.

How does a starter motor work on a car?

When you turn the ignition, it should send power to the starter motor and at the same time send a signal to the starter solenoid to engage. When the starter solenoid is receiving the signal, it engages a gear that is pushed out to engage to the flywheel to spin the engine.
