A6 ASE Practice 2

Two technicians are discussing an analog transmission range sensor on a late model vehicle. Technician A says that since these sensors use resistance to indicate gear selection, they can be tested with an ohmmeter. Technician B says to start the car and make sure the circuit is powered before using the meter. Who is correct?

• Technician A

• Technician B

• Both

• Neither

Which solder should be used when repairing an automotive electrical connection?

• Rosin Core

• Silver

• Acid Core

• Zinc

Technician A says a voltage limiter is used in an instrument panel to keep the voltage at 5 volts. Technician B says if the limiter is faulty, it may result in high gauge readings. Who is correct?

• Technician A

• Technician B

• Both

• Neither

This multi meter reading shows what?

• .016 Ohms

• .016 Volts

• 16 Ohms

• 16 volts

Two technicians are discussing the waveform in the image above. Technician A says the TP sensor in the image is defective. Technician B says the vehicle may hesitate during acceleration. Who is correct?

• Technician A

• Technician B

• Both

• Neither

A vehicle's factory alarm system activates on its own. Technician A says this could be a faulty courtesy light switch. Technician B says an intermittent problem with a trunk or hood switch can cause this activation. Who is correct?

• Technician A

• Technician B

• Both

• Neither

This symbol is for what?

• Battery

• Motor

• Variable Resistor

• Ground

A vehicle's battery continues to discharge while sitting overnight. Technician A says to perform a parasitic battery drain test. Technician B says this could be a slow drain caused by a faulty alternator. Who is correct?

• Technician A

• Technician B

• Both

• Neither

An alternator output test is being performed on a vehicle's charging system. Technician A says engine idle must be increased during this test. Technician B says the vehicle's accessories must be turned on during this test. Who is correct?

• Technician A

• Technician B

• Both

• Neither

A technician is performing a starter current draw test on a four-cylinder engine. The engine cranks slowly and has a current draw of 340 amps. Which of the following is correct?

• The current draw is within spec

• The starter has worn bushings

• The starter has worn brushes

• There is excessive resistance in the this circuit
