2. If a fuse blows again after it has been replaced, what is the most likely cause:

Explanation

A drop in circuit resistance will cause current flow to increase.

Submit
3. Technician A says a voltmeter is connected in series to measure voltage. Technician B says it is connected in parallel. Who is correct?

Explanation

Voltmeters are connected in parallel or across a circuit.

Submit
4. In using a voltmeter to measure the voltage drop across a resistance, the two leads are:

Explanation

A voltace drop measurement is the fastest way to identify resistance problems.

Submit
5. The analog voltmeter reading shown below is:

Explanation

2.2 volts with the slector knob set to the 4.0 volt range

Submit
6. A DVOM (digital volt meter) is being used to measure current flow. The meter indicates 154 mA. Technician A says this is 0.154 amps. Technician B says this is 1.54 amps because the decimal point must be moved 4 decimal points to the left.

Explanation

To convert mA to A, move the decimal point three places to the left. 1000 mA equals 1 A.

Submit
7. Before connecting an ohmmeter to a circuit, you should first:

Explanation

Voltage will damage the ohmmeter. Verify the cirucit is electrially dead.

Submit
8. What can cause an excessive voltage drop?

Explanation

Electrons will give up voltage as heat to get past the resistance.

Submit
9. A Digital Ohmmeter is being use to measure a component. The meter indicates 3.725K ohms. This indicates

Explanation

The K equals 1000. Move the decimal point three places to the right (replace the K with three zeros).

Submit
10. Oscilloscopes can be used to

Explanation

Oscilloscopes display the shape of voltage waveform over a period of time.

Submit
11. When using an ammeter to measure current:

Explanation

Amp meters are placed in series with a working circuit to measure current.

Submit
12. When measuring an unknown voltage or current, set the range selector at:

Explanation

Always start at the highest settings and work down.

Submit
13. When performing a continuity check using a Fluke digital ohmmeter, a reading of 'OL' would indicate:

Explanation

OL means over limit (open circuit).

Submit
14. To measure the voltage drop of a connector, the volt meter should be connected:

Explanation

The circuit must remain intact with a voltmeter lead attached on each side. The voltmeter will measure the difference in electrial voltage potential (voltage drop) between each of the two voltmeter leads.

Submit
15. A fuse burns out whenever the Brake pedal (stop light switch) is depressed, Technician A says a short circuit is present before the switch and a short finder is required. Technician B says the short circuit is complete when the switch is closed and must be after the switch. Who is correct?

Explanation

Since the fuse blows only when the pedal is depressed, it must be after the switch but before the load .

Submit
16. The voltmeter in the circuit below should read:

Explanation

With an open switch, source voltage runs all the way to the open.

Submit
17. Referring to the picture below, Technician A states that a voltmeter is the best meter for measuring for an unwanted battery drain. Technician B states that an ammeter is the best meter to use for checking for an excessive battery drain, because it measures how much of a drain there is. Who is correct:

Explanation

An amp meter in series with the battery will allow you to measure battery drain.

Submit
18. Technician A says that a digital meter is preferred to an analog meter when measuring sensitive computer circuits. Technician B says that an analog meter might overload a computer circuit. Who is correct?

Explanation

Both statements are true.

Submit
19. When checking a normally open relay (with four terminals) with and ohmmeter, no continuity will be shown between two terminals and the other two terminals will show:

Explanation

Many automotive relay will have control coil resistances of 40 ohms to 120 ohms.

Submit
20. A pulsing voltage is easiest to read on

Explanation

Pulsating voltages are easiest read on an analog meter.

Submit
21. In solid state circuits, the following must be used:

Explanation

High impedance meters are required on solid state circuits. All digital meters are high impedance meters.

Submit
22. he lamp in the circuit below glows dimly. A voltmeter indicates 12.6 volts at the lamp. Technician "A" says that a bad ground at the lamp could be the cause. Technician "B" says that high resistance in the circuit from the battery to the lamp could be the cause. Who is correct?

Explanation

With source voltage at the lamp the circuit up to that point is funtioning correctly.

Submit
23. With all accessories turned off, the current (Parasitic) drain on the battery should be:

Explanation

For most current model vehicles, parasitic drain should be under 35 milliamps.

Submit
24. An audible short finder is being used. The transmitter is placed at the fuse box and the receiver is passed along the wire. Technician A say it will be beep rapidly at the point of ground (short). Technician B says that it will beep only when the short is located. Who is correct?

Explanation

The tone will increase at the short then decrease as you move away.
