- 1What is the purpose of the starter motorChanges electrical energy into mechanical energy to rotate the engine for startup
- 2What two functions does the starter solenoid accomplishFirst, it moves the mechanical drive to engage the pinion gear into the flywheel. Second, it closes a set of
contacts to energize the starter motor once the pinion gear is meshed with the flywheel - 3What occurs when the coil of a crank relay energizesThe crank relay contacts close providing a path of current flow to the starter solenoid
- 4Which battery-charging alternator components turn on the alternator when voltage drops below a preset levelVoltage regulator
- 5What do you inspect on a starter and a starter solenoida
- 6What are the first two things you do when replacing a starter motor and solenoidInspect the starter solenoid terminals for corrosion, inspect the starter and starter solenoid for signs of
damage and security of mounting bolts, and look for discoloration or other signs of overheating of the starter
motor and starter solenoid - 7Why must you ensure you keep correct polarity when reinstalling a starter motorDisconnect the negative cable from the battery terminal and tag and disconnect the electrical leads from the
starter motor - 8What can happen if a charging rate is too highYou may damage the battery and other electrical component
- 9What must you do before working on a battery-charging alternatorYou can damage the battery.
