Starting & Charging Systems Review #1

A starter motor should be operated:

• For as long as it takes for the engine to start

• at least 5 minutes

• unitl it is red in color

• no longer than 15 seconds

The component that engages and rotates the ring gear is called the _________ gear.

• sun

• 3rd

• round

• pinion

A starter motor can rotate the engines crankshaft to

• 20 RPM

• 200 RPM

• 2,000 RPM

• Engine Redline

A tech measures 2 volts when conducting a voltage drop test on the starting system. This indicates

• A normal opeating condition

• A bad starter motor

• A bad battery

• A problem in the starter system wiring

Which of the following is the rotating part of the starter motor?

• Brushes

• Permanent Magnets

• Armature

• Field Coils

What component is used to switch a large current to the motor.

• Voltage regulator

• Commutator

• Solenoid

• Brushes

What component prevents the starter motor from engaging when the transmission is in reverse?

• Clutch Switch

• Pole shoe

• Ignition Lock

• Neutral Safety Switch

A starter motor uses a small pinion to turn a large ring gear. This is done to:

• To develop a mechanical advantage

• To develop a mechanical disadvantage

• To slow the engine rotation

• To heat up the starter motor quicker

The main starter cable is:

• Small to reduce voltage drop

• Small to reduce heat

• Large due to high current flow

• Large due to minimal current flow

The starter ring gear is:

• A) mounted to the flywheel/flex plate

• B) has more teeth than the pinion gear

• C) made of brass

• D) both A and C
