ASE A6 Practice Test

Which of these is true about a series circuit?

What tool can check continuity in wires that carry digital signals?

While you use a DMM voltmeter function to evaluate voltage drop, the meter leads need to be connected in what way?

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

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?

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?

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?

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?

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?

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

The vehicle turn signals begin to flash too slow. Technician A believes that the issue is caused by a faulty flasher. Technician B believes the bulb is an incorrect type.

Who is correct?

What solder type is needed for instrument panel wiring repair?

When a faulty fuel gauge indicates a full tank, what’s the most likely reason?

The rear defogger grid is being tested. Technician A believes that the voltmeter should decrease its reading while probing a grid line as it gets close to the ground bus bar.

Technician B believes that when the voltmeter reads 12 volts at both ends of the grid line, it means there’s an open in the grid line. Who is correct?

The power seat system is noisy when operated. All of these might be the cause EXCEPT:

The horn is making a weak sound. Technician A believes the faulty power connection is the reason. Technician B believes the faulty fuse might be the cause.

Who is correct?

The doors on a vehicle won’t unlock with the remote keyless entry. These could all be the cause EXCEPT:

The vehicle sunroof works intermittently. Technician A states that it might be a poor wiring connection. Technician B states that the panel might be binding in the rails.

Who is correct?

How many 2.1-volt cells are in a standard 12-volt car battery?

According to Kirchhoff’s Voltage Law, the sum of all the voltage drops in a closed loop system are going to be equal to ________.
