ELECTRICAL SYSTEMS TROUBLESHOOTING (CONT)
(Sheet 4 of 7)
PROBLEM NO. 25 (CONT)
25 a. When the TAIL/PANEL LIGHT switch is closed, current flows from fuse 3, through the switch and through the tail lamps to ground. Current
also flows to the panel light circuit, therefore, if panel lights and gages work, the problem is either at the tail lamps or in the GY wire between
the DK BL connector at Right Hand Instrument Panel (RHIP) and the tail lamps.
If only Right Hand (RH) tail lamp is out test bulb and check ground. If only Left Hand (LH) tail lamp is out test bulb, check ground and GY
wire from RH tail lamp.
If panel lights do not come on, problem is either at fuse (see NOTE) or switch or in wiring from fuse to Left Hand Instrument Panel (LHIP)
If auxiliary flood lights work, problem is not at fuse.
