1979 model, I believe that it has the late 1979+ electrics. Keyed ignition and good battery that tests at 12v+
The taillight illuminates with the key in the on position. The headlight illuminates with the engine running. The horn works when connected directly to a 12v source. The horn circuit has continuity as tested with a multimeter when the horn button is depressed. Iíve found the wiring diagram online but Iím an amateur with electrics requiring cookbook instructions to complete a task.
Do the ignition and run switches need to be on to operate horn, brake, and blinker? From what Iíve read, they all operate off the battery and donít require the engine to be running to operate.
Iíd love some guidance on where to go from here in diagnosing and fixing the non-operable brake light, turn signal, and horn.
