Five-step troubleshooting

1. Verify the problem

Turn on all the components in the problem circuit to check the accuracy of the customer complaint. Note the
symptoms. Do not begin disassembly or testing until you have narrowed down the problem area.

2. Analyze the circuit schematic

Look up the schematic for the problem circuit.
Determine how the circuit is supposed to work by tracing the current paths from the power source through
the circuit components to ground. Also, trace circuits that share wiring with the problem circuit. The names
of circuits or components that share the same fuse, ground, or switch, and so on, are referred to in each
circuit schematic. Try to operate any shared circuits you didn't check in step 1. If the shared circuits work,
the shared wiring is OK, and the cause must be in the wiring used only by the problem circuit. If several
circuits fail at the same time, the fuse or ground is a likely cause.
Based on the symptoms and your understanding of the circuit's operation, identify one or more possible
causes.

3. Find the cause

Make circuit tests to check the diagnosis you made in step 2. Keep in mind that a logical, simple procedure
is the key to efficient troubleshooting.Test for the most likely cause of failure first. Try to make tests at points
that are easilyaccessible.

4. Repair the problem

Once the specific problem is identified, make the repair.
Be sure to use proper tools and safe procedures.

5. Check the repair

Turn on all components in the repaired circuit in all modes to make sure you've fixed the entire problem. If
the problemwas an open fuse, be sure to test all of the circuits on that fuse.
Make sure on new problem turn up and the original problem does not recur.

Test equipment

Most circuits include solid-state devices. Test the voltages in these circuits only with a 10-megaohm or
higher impedance digital multimeter.
Never use a test light or analog meter on circuit that contain solid-state devices. Damage to the devices
may result.

Test light and DVOM

On circuits without solid-state devices, use a test light to check for voltage. A test light is made up of a 12-volt
bulb with a pair of leads attached.
After grounding one lead, touch the other lead to various points along the circuit where voltage should be
present. The bulb will go on if there is voltage at the point being tested.
If you need to know how much voltage is present, use a digital volt/ohmmeter (DVOM).

Self-powered test light and DVOM

1. Use a self- powered test light to check for continuity.

This tool is made up of a light bulb, battery, and two leads. To test it, touch the leads together, the light
should go on.
Use a self-powered test light only on an unpowered circuit. First, disconnect the battery, or remove the fuse
that feeds the circuit between which you want to check continuity.
Connect one lead of the self-powered test light to each point. If there is continuity, the test light's circuit will
be completed, and the light will go on.

Fused jumper wire

Use a jumper wire to bypass an open circuit. A jumper wire is made up of an in-line fuse holder connected to a
set of test leads. It should have a five ampere fuse.
Never use a jumper wire across any load. This direct battery short will blow the fuse.

Short finder

1. Short finder are available to locate shorts to ground. The short finder creates a pulsing magnetic field in the

shorted circuit and shows you the location of the short through interior trim. Its use is explained in the
following troubleshooting tests.

Testing for voltage

This test measures voltage in a circuit. When testing for voltage at a connector, you may not have to separate
the two halves of the connector. Instead, probe the connector from the back. Always check both sides of the
connector because dirt and corrosion between its contact surfaces can cause electrical problems.

1. Connect on lead of a test light to a known good ground, or if you are using a voltmeter, be sure you connect

its negative lead to ground.

2. Connect the other lead of the test light or voltmeter to the point you want to check.

3. If the test light glows, there is voltage present. If you are using a voltmeter, note the voltage reading. It

should be within one volt of measured battery voltage. A loss of more than one volt indicates a problem.

Testing for continuity

This test checks for continuity within a circuit. When testing for continuity at a connector, you may not have to
separate the two halves of the connector.Instead, probe the connector from the back. Always check both sides
of the connector because dirt and corrosion between contact surface can cause electrical problems.

1. Disconnect the negative cable from the vehicle battery.

2. If you are using an ohmmeter, hold the leads together and adjust the ohmmeter to read zero ohms.

3. Connect one lead of a self-powered test light or ohmmeter to one end of the circuit you wish to test.

4. Connect the other lead to the other end.

5. If the self-powered test light glows, there is continuity. If you are using an ohmmeter, low or no resistance

means good continuity.

Testing for voltage drop

This test checks for voltage drop along a wire, or through a connection or switch.

1. Connect the positive lead of a voltmeter to the end of the wire (or to the side of the connector or switch)

closest to the battery.

2. Connect test negative lead to the other end of the wire (or the other side of the connector or switch).

3. Operate the circuit.

4. The voltmeter will show the difference in voltage between the two points. A difference, or drop of more than

0.5 volts, may indicate a problem.

Testing for a short to ground with a test light or voltmeter

1. Remove the open fuse and disconnect the load.

2. Connect a test light or voltmeter across the fuse terminals. Make sure voltage is being applied to the battery

side fuseterminal. Check the schematic to see if the ignition switch needs to be in the "ON" position.

3. Begining near the fuse box, wiggle the harness.

Continue this process at convenient points about six inches apart while watching the test light or voltmeter.

4. When the test light blinks or the voltmeter needle moves, there is a short to ground in the wiring near that

point.
