LV03.2 Remove and Replacing Electrical Units and Components MF

The alternator stator is found

• In the slip ring

• In the rotor

• In the rectifier

• In the casing

To power a heavy duty 12 volt starter motor, you may need to connect two 12 volt batteries:

• In parallel

• In the boot

• In series/parallel

• In series

In a vehicle alternator the rectifier pack:

• Converts DC to AC

• Converts AC to DC

• Has a zener diode

• Regulates the voltage

If R1 fails in this lighting circuit what will happen to R2 and R3?

• They will both stay lit

• Only R2 will stay lit

• Only R3 will stay lit

• Both will go out

What is the maximum amperage this meter can measure?

• 10A

• 3A

• 400A

• 200A

To avoid damaging an ammeter you should only connect it:

• In parallel with circuit components

• In series with circuit components

• Between positive and negative

• Between negative and positive

How should a voltmeter and ammeter be connected to measure the resistance in a switch?

• The voltmeter and the ammeter should both be connected in parallel with the switch

• The voltmeter and the ammeter should bothe be connected in series with the switch

• The ammeter should be connected in parallel and the voltmeter in series with the switch

• The voltmeter should be connected in parallel and the ammeter in series with the switch

The light from a front fog light is dim. Which of the following is NOT a possible cause of the fault?

• Corroded earth connection

• Corroded light reflector

• Open circuit supply cable

• Corroded supply cable

When the starter switch is operated the pre-engaged starter motor turns the engine very slowly. Which of the following is NOT a possible cause of the fault?

• A corroded battery connection

• A loose starter cable

• A partially discharged battery

• A defective roller clutch

The diagram shows three resistors. If the resistor R1 is 1 ohm, R2 is 0.5 ohm and R3 is 1.5 ohm, what is the reading on the ammeter (A) when the switch is closed?

• 9 Amps

• 4 Amps

• 3 Amps

• 36 Amps
