Troubleshooting Hints
- 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. After you repair the cause of the overload, replace the circuit breaker.
- Inspect ground G210 in order to ensure that the ground is clean and tight.
- Inspect for a broken (or a partially broken) wire inside the insulation. This condition could cause system malfunction but may 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.
- Inspect for the proper installation of the aftermarket electronic equipment which may affect the integrity of other systems.
