• B. On the positive side of the circuit

• C. In series with the circuit

• D. Across the circuit or component

An analog ohmmeter needle won’t move when connected to both sides of the rotor. What does this mean about the rotor winding?

• A. It is grounded

• B. It is shorted

• C. It is open

Technician A states that a short circuit to ground in a circuit decreases resistance. Technician B states that a short circuit increases current flow. Who is correct?

• A. Technician A

• B. Technician B

• C. Both technicians

• D. Neither technician

Two technicians discuss the state of charge of a battery. Technician A states that a specified gravity of 1.225 at 80F shows the battery has a state of charge at about 75%. Technician B states that it’s possible to use the hydrometer to check the state of charge if you are troubleshooting a maintenance-free battery. Who is correct?

• A. Technician A

• B. Technician B

• C. Both technicians

• D. Neither technician

While performing a starter current draw test, you notice the current draw is more than specified. The battery voltages and cranking speed appear to be less than specified. What is the cause of your problem?

• A. High resistance in the field windings

• B. A burned solenoid disc and terminals

• C. Worn bushings in the starter motor

• D. High resistance in the battery positive cable

While discussing an alternator that has zero output, Technician A states that the field circuit might have an open circuit. Technician B states that the fusible link might be open to the alternator from the battery. Who is correct?

• A. Technician A

• B. Technician B

• C. Both technicians

• D. Neither technician

Technician A states that a loose serpentine alternative drive belt might lead to overcharging. Technician B states that undersized wiring between the battery and alternator might cause undercharging. Who is correct?

• A. Technician A

• B. Technician B

• C. Both technicians

• D. Neither technician

What would be the least likely reason you experience a dim headlight out of these options?

• A. Low output from the alternator

• B. Headlight connector is corroded

• C. Headlight wiring has high resistance

• D. Broken or damaged headlight assembly
