Trouble Shooting: Notes

Before proceeding to SYSTEM TESTS, perform the following visual inspections:

• Check appropriate circuit breakers and fuses. If circuit breakers or fuses are blown, service and repair source of overload. Replace circuit breakers and fuses.
• Check for mechanical failures or binding linkage.
• Check for broken or partially broken wire inside insulation, which could cause system malfunction but prove good in a continuity/voltage check with system disconnected. These circuits may be intermittent or resistive when loaded. Check by monitoring voltage drop with system under load.
• Check for proper installation of aftermarket electronic equipment.
