the modern starter drive pinion gear is moved into mesh with the ring gear teeth by..

• inertia

• one way clutch action

• a shift fork

• a string magnetic field created in the ring gear

most starter solenoids that are mounted directly on the starter motor have two windings called the..

• lap and wave

what is the purpose of the neutral safety switch?

• to prevent the starter from operating if the engine is running

• to prevent the starter from operating unless the gear shift lever is in the proper position

• to protect the starter from burning out

• to shut off the starter if current draw becomes to high
