1. An air bag is being serviced, Technician A says to disconnect the yellow SRS connector at the front of the vehicle. Technician B says to disconnect and isolate the negative battery cable. Who is right?

• Technician A only
• Technician B only
• Both Technician A & B
• Neither A 0r B

2. The connection of a lead- acid battery is being checked. Technician A says use a Galvanometer. Technician B says use a capacitive battery tester. Who is right?

• Technician B only
• Both Technician A & B
• Neither A 0r B

3. Technician A says that a noisy Alternator could be caused by bad diode. Technician B says that a noisy Alternator caused by worn bearings. Who is right?

8. Nothing happens when the Ignition key is turned to START position in a vehicle with a good battery. Technician A states a clicking in the starter control circuit.sound heard when a jumper wire is connected between the battery and the solenoid"S" terminal, a problem exists in the starter control circuit. Technician B says that if a jumper wire is connected between the battery and the solenoid "S" terminal and there is no sound the starter is defective. who is correct?
