Hi
My 73 2.0 914 has a few odd electrical probs I'm trying to fix. The most obvious is that it won't turn off when the lights are on and my foot is on the brake. Corrolary: lights on key on engine not running pressing brake primes fuel pump.
What I know/have done: by pulling fuses narrowed it down to fuse 8 circuit. Oddly (to me) measured 8v on circuit 7. I assume it should be 12.
Cleaned all the grounds I could find. Attached a long wire from batt negative to my multimeter and metered at all the grounds to see if there was a difference in potential. Less than .1v.
The wiring is somewhat burned and rather hacked under a PO. Would love to both fix this issue and get the wiring closer to factory. Haynes manual seems a poor reference to understand the factory connections, wiring design, etc. Can you suggest how to proceed? Is there, for example, a picture/annotated diagram of what wires are attached to the fuse panel? Such a rats nest!
