Car runs, but no interior electronics?

[JohnnyP]

After some tinkering, I got my 76 280 running, she's looking good. However, I have almost no functioning interior electronics. Here is what DOES work (interior/exterior):

Exterior

ALL exterior lights

Interior

Fuel gauge

Voltmeter (whatever its called)

Im not getting any functionality from any other of the interior devices, no horn either (just a clicking sound from the pass side firewall). Im sorry if this is to vague, Im Im new to Z's, but I do know that this forum is amazing for helping with these wonderful machines! Any responses are appreciated.

Thanks again,

John

I don't know the specifics of the '76, but check your fusible links and your relays. At least on the '78, the major segments of the fuse block are each fed by relays, which receive power from the fusible links.

what she said, sounds like an Acc. relay or something along those lines.

A wiring diagram and a multimeter will serve you well now, alowing you to easily track down this problem, as well as in the future, when other problems arise. I actually find trouble shooting electrical problems fun when the car is in front of me, but it can be difficult online, when the information and feedback isn't spontanious. The clicking you hear when you press the horn button is the horn relay. That is normal and is only the control side of the relay doing it's job.

It's more than likely something small. Have you already checked the fuses?

Saridout was nice enough to make us all a full-color wiring diagram for this year, it'll probably come in handy.

I did check the fusible links, I had another problem and needed to eliminate the that part as a suspect.

From what I can tell the fuses are good. Im not sure about the relays - I do not know where they are located or how exactly to check them. I am still getting used to the Z, and cars in general, please forgive my ignorance.

Thanks for the link for the color wiring diagram above, that will most definitely come in handy.

Thanks for the assistance everyone
