A vehicle's air conditioner blower motor will only work if the selector is in the high position. Technician A says to check the blower motor resistor. Technician B says this is most likely a loose ground connection. Who is correct?

A full-fielded 70 amp alternator only produces 45 amps. The MOST likely cause of this is:

The headlights get brighter as a vehicle is accelerated. Technician A says this is caused by a high capacity battery. Technician B says this is caused by high charging system voltage. Who is correct?

A technician replaces a blown fuse in a dome light circuit and the element in the fuse melts immediately. Technician A says if a dome light keeps blowing fuses to check for a short to ground. Technician B says resistance in this circuit has increased current flow. Who is correct?

All the lights in a brake light circuit illuminate except one. The MOST likely cause is:

If a technician reversed the leads of a digital voltmeter on a 12 volt circuit the readout would show:

A vehicle's battery is being tested for capacity. Technician A says during a battery capacity test the voltage should not drop below 9.6 volts at 70° F. Technician B says a battery's voltage reading should increase as temperature decreases. Who is correct?

This multi meter reading shows what?

This symbol is for what?

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?

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?

Which of the following can be checked in the starter circuit with a voltage drop test?

A technician would use an ohmmeter to test

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?
