dash board lights

If you have a Rallye dash (oil pressure gauge) the VR is inside the fuel gauge. Has nothing to do with lights, is only for temp/ fuel / oil gauge

The dash lighting is a bit of a trick. Is is supplied TO the light switch from the tail fuse. So that circuit must be good fuse and working.

Then it goes through the dash dimmer, and then down to the fuse panel to the INST fuse, the small fuse at one end of the fuse panel. OUT of that little fuse, the lighting is distributed on ORANGE wiring.

Start with tail lights on, dimmer twisted to left. Check for power on that inst fuse. If not, go up to the dimmer / light switch
