Electrical test Yea

An airbag is being serviced, tech a says to disconnect the yellow SRS connectors at the front of the vehicle, tech b says to disconnect and isolate the negative battery cable, who is right?

• Tech A only

• Tech B only

• Both tech A and B

• Neither tech A or B

When performing electrical repairs, which of these should be used when soldering electrical wiring connectors?

• Acid core flux

• Sulfur core flux

• None of the above

• Rosin core flux

When testing computer controlled systems, a DMM should be used with an input impedance of at least:

• 10M OHMS

• 1M OHM

• 10K OHMS

• 100KOHMS

When troubleshooting a show drain on the battery, which of these diagnostic tools should be used?

• Ohmmeter

• Ammeter

• Voltmeter

• Test light

What test would you be performing in the preceding question?

When performing which electrical test do you need the circuit disconnected and isolated from power?

• Voltage drop

• Static voltage

• Circuit amperage

• Resistance

Nothing happened when the ignition key is turned to the start position in a vehicle with a good battery. Tech a says that if a clucking sound is heard when a jumper wire is connected between the battery and the s terminal ok the solenoid, problem exists in the starter control circuit. Tech b says that's if a jumper wire is connected between the battery and the s terminal on the solenoid and there is no sound, the starter is defective, who is right?

• Tech a only

• Tech b only

• Both a and b

• Neither a and b

The horns in the circuit shown operate only when a jumper wire is connected between the terminals 30 and 87 of the horn relay. Tech a says that a failed horn relay could be the cause. Tech b says that a shirt to ground in the circuit between the horn relay and the horn switch could be the cause, who is right?

• Tech a only

• Tech b only

• Both a and b

• Neither a or b

The rear defogger grid is being tested, tech a days that when probing a grid line the voltmeter should decrease its reading as the probe gets closer to the ground bus bar, tech b says that if the voltmeter reads 12 volts at both ends of the grid line there is an open in the grid line. Who is right?

• Tech a only

• Tech b only

• Both tech a and tech b

• Neither tech a or b

All of the following are used when applying ohms law except?

• Amperes

• Watts

• Ohms

• Voltage
