Charging Systems

Alternator rebuild typically involves all of the following steps except:

• Testing the Diodes

• Testing the Stator

• Replacing the Harmonic Balancer

• Replacing The defective Bearings

During a 12-volt charging system voltmeter test, all electrical accessories are on when checking ____ voltage.

• Base

• Load

• No Load

• Cranking Load

An electronic voltage regulator cannot be repaired.

• True

• False

To reduce output of the alternator, the electronic voltage regulator introduces more resistance between the rotor windings and battery.

• True

• False

Most modern laptop computers and diagnostic tablets have a scope function.

• True

• False

If the no-load voltage is more than 2–3 volts higher than base voltage, the alternator is overcharging the battery.

• True

• False

The only way to obtain accurate charging system test results is to use a digital VOM (volt-ohm-ammeter).

• True

• False

Reversing polarity of electrical connections can destroy circuits in the regulator and severely damage alternator diodes.

• True

• False

The alternator pulley is usually brazed onto the end of the rotor shaft.

• True

• False

An alternator fan cools windings and diodes to prevent overheating and damage.

• True

• False
