TROUBLESHOOTING HINTS
1. Inspect the condition of the AUX, BU and IGN3 circuit breakers. If any circuit breaker is open Locate and Repair the cause of the overload and
then Replace the circuit breaker.
2. Inspect Ground G210 to make certain that it is clean and tight.
3. Inspect for broken (or partially broken) wire inside the insulation. This condition could cause system malfunction but prove to test good in a
continuity or voltage test with the system disconnected. These circuits may be intermittent or resistive when in operation. If possible test for a
voltage drop when the system is operational.
4. Inspect for proper installation of aftermarket electronic equipment which may affect the integrity of other Systems.
