What electronic components are used in the alternator rectifier?

• Zener diodes

• Transistors

• Diodes

• Resistors

Identify the component shown below.

• Pre-engaged drive

• Inertia drive

• Axial drive

• Co-axial drive

What does the term Watt mean?

• Electrical pressure

• Electrical current

• Electrical resistance

• Electrical power

You have been asked to test a stator with a suspected broken winding. How would you test the stator?

• Using an ohmmeter connected to the output wires. Typical values should be 100 ohms

• Using an insulation tester between each wire and the iron lamination not lighting the bulb

• Using an insulation tester between each wire and the iron lamination lighting the bulb

Identify the component shown below.

• Pre-engaged starter motor

• Co-axial starter

• Axial starter

• Inertia starter

To test the rectifier you should test:

• negative diodes and positive diodes as a set using an insulation tester

• each diode separately, current should flow in only one direction

• each diode separately, current should flow in both directions

• each diode separately, current should not flow in any direction

What should the charging rate be of a serviceable alternator on a 12V vehicle running at approx 2000rpm?

• 12 to 13.6 Volts

• 12.6 to 13.8 Volts

• 13.8 to 14.4 Volts

• 14.4 to 15.2 Volts

According to the theory of magnetism, which of these statements is correct?

• Norths attract souths and souths attract souths

• Norths attract norths and souths attract norths

• Norths attract souths and souths attract norths

• Norths attract norths and souths attract souths

You have stripped the starter motor and found that the commutator surface is poor. How would you repair this?

• Skim the commutator in a lathe and then undercut the insulation

• Skim the commutator in a lathe and then polish it with emery paper

• Repair the commutator using emery paper and then undercut the insulation

• The commutator cannot be repaired, as it must remain its original thickness

Identify the component shown.

• Stator

• Slip ring

• Surge protection diode

• Rectifier
