Which of these components is the stator?

An alternator stator with three windings usually has how many diodes?

Some alternators are cooled by engine coolant.

Which of these is TRUE about an alternator with an overrunning pulley?

A duty cycle of 90% means the circuit is off most of the time.

How much current flows through the alternator brushes?

One horsepower is equal to ________ watts.

The output diodes in an alternator are mounted to which of these components?

The GM electrical power management system has 3 modes of operation.

Current for the rotor flows through the brushes to the ________.

On a vehicle using an electrical power management system (EPM), how is the current to the battery measured?

Alternators induce voltage by rotating which of these?

Which of these facts is correct about a delta-wound stator?

Electronic voltage regulators use a temperature-sensitive resistor in the regulator circuit. This resistor, called a thermistor, provides lower resistance as the temperature ________.

Technician A says that a magnetic field is created in the alternator rotor. Technician B says that alternator output is increased if the speed of the alternator is decreased. Who is right?
