WIRING HARNESS TROUBLESHOOTING AND MAINTENANCE PROCEDURES.
TEST OR INSPECTION
Step 5. Observe the multimeter needle movement.
If the multimeter needle moves to the right over zero on the top of the scale, the circuit has continuity. The
wiring harness is not the problem.
If the multimeter needle does not move, the circuit does not have continuity. Replace wiring harness.
If the multimeter needle jumps or flickers, the wiring harness being tested has a loose connection. Further
testing will be necessary.
