Troubleshooting Wiring Problems
When troubleshooting wiring problems there are six steps which can aid in the procedure. The steps are listed and
explained below. Always check for non-factory equipped components added to the vehicle before doing any diagno-
sis. If the vehicle is equipped with these items, disconnect them to verify these add-on items are not the cause of the
problem.
Perform the following when troubleshooting a wiring problem:1. Verify the problem.
2. Verify any related symptoms (do this by performing operational checks on components that are in the same circuit).
3. Analyze the symptoms (use the wiring diagrams to determine what the circuit is doing, where the problem most likely is occurring and where the diagnosis will continue).
4. Isolate the problem area.
5. Repair the problem area.
6. Verify the proper operation (for this step, check for proper operation of all items on the repaired circuit).
Testing For Voltage
1. Connect the ground lead of a voltmeter to a known good ground.
2. Connect the other lead of the voltmeter to the selected test point. The vehicle ignition may need to be turned ON to check voltage. Refer to the appropriate test procedure.
Testing For Continuity
1. Remove the fuse for the circuit being checked or, disconnect the battery.
2. Connect one lead of the ohmmeter to one side of the circuit being tested.
3. Connect the other lead to the other end of the circuit being tested (low or no resistance means good continuity).
Testing For A Short To Ground
1. Remove the fuse and disconnect all items involved with the fuse.
2. Connect a test light or a voltmeter across the terminals of the fuse.
3. Starting at the fuse block, wiggle the wiring harness about six to eight inches apart and watch the voltmeter/testlight.
4. If the voltmeter registers voltage or the test light glows, there is a short to ground in that general area of the wiring harness.
Intermittent and Poor Connections
Most intermittent electrical problems are caused by faulty electrical connections or wiring. It is also possible for a
sticking component or relay to cause a problem. Before condemning a component or wiring assembly, check the
following items:
1. Connectors are fully seated
2. Spread terminals, or terminal push out
3. Terminals in the wiring assembly are fully seated into the connector/component and locked into position
4. Dirt or corrosion on the terminals (any amount of corrosion or dirt could cause an intermittent problem)
5. Damaged connector/component casing exposing the item to dirt or moisture
6. Wire insulation that has rubbed through causing a short to ground
7. Some or all of the wiring strands broken inside of the insulation
8. Wiring broken inside of the insulation

Wire Repair
NOTE :
When splicing a wire, it is important that the correct gage be used.1. Remove one-half (1/2) inch of insulation from each wire that needs to be spliced.
2. Place a piece of adhesive lined heat shrink tubing on one side of the wire. Make sure the tubing will be long enough to cover and seal the entire repair area.
3. Place the strands of wire overlapping each other inside of the splice clip.
4. Using a crimping tool, crimp the splice clip and wires together.
NOTE :
Do not use acid core solder when making wiring repairs. 5. Solder the connection together using a soldering iron and rosin core type solder only.
6. Center the heat shrink tubing over the joint and heat using a heat gun. Heat the joint until the tubing is tightly sealed and sealant comes out of both ends of the tubing.
Fuse Replacement
•When replacing a fuse, be sure to replace it with
one of the same capacity. If a fuse fails again, the
circuit probably has a short and the wiring should
be checked.
• Be sure the negative battery terminal is discon-
nected before replacing a main fuse.
• When replacing a pullout fuse, use the fuse puller.
