I now have reconnected the electrical wiring at the dash and light fixtures that the PO had disassembled. I installed 15 and 25 amp fuses (replaces Lucas 35 and 50 fuses). Connected a warning light at the + battery terminal to ground. A few things are not connected and, they get power from the A4 terminal on the fuse block: Brake light, Reverse light, heater fan, wiper motor and wires to wiper switch.
Clock and fuel pump are not connected.
Near the firewall there are 3 wires from the loom with bullet connectors, their destination is still to be determined.
Both rubber bullet connector blocks on the fender walls, 5-way on right and 10 way on left, have been replaced and ground clips renewed, attachment points on fender sanded to bare metal.
My electric system function results:
Horn - weak buzz and warning light on (connected to A4 terminal)
Turn signal: right side - warning light flashes, Turn signal left side – nothing. (connected to A4 terminal)
Sidelight: Dim orange glow, warning light on.
Headlight: Nothing, warning light on.
Foglight: No Foglights connected, warning light on when switch activated.
Panel lights – nothing.
Taillight – nothing.
License plate light – nothing.
This works:
IGN light illuminated with key on.
Interior Light switch provides power to lights.
I have no idea how to troubleshoot the above faults and wondering if the HL switch faults might be located before the HL switch? And, could the horn and turn signal problems be related to the other A4 equipment that is not yet connected? Thanks
