I am wiring the dash of my fieero 3800sc GT(p). I tried to label all my wires when I removed the old dash but I seem to have lost my voltage wire. If I were to rerun my wire for the voltage meter where would I wire it to on my engine?
Well, in spite of your kind advice, I had to go to my friend (who explains things to me as if I were a child) and he advised me i have an alternator not a generator and told me what the meter shows is "what is going into the battery when the engine is running. That, he said will be about 14 volts. When I turn the ignition to the on position that is what is in the battery now which I would guess was 12 volts. The important thing was to get a wire that is on only when the key is in the on, start and run position. If I had problems with the starter not working I could look at the meter and tell immediately if it was because of a bad battery or not a bad battery. He also told me never to run the car without a battery.
I have to admit though, it would seem to me with there being 14 volts coming from the alternator and the 12 volts in the battery that there would be some problem in the differences in the electromotive force and it would somehow average out or something. So, tomorrow I have a good idea where to find such a wire. Also, realize my dash has been completely disassembled and all of the gauges replace with aftermarket gauges and others added, such as boost, transmission temperature and oil temperature.
I would show you pictures of my dash but I'm too embarrassed with all the extra wires dangling down. I did though carefully label wires as I traced them to their destination. In a couple of cases though, the label came off so I kind of have to punt. I'll put some pictures up when I have the dash and console done. It is yellow diamond plate.
Can't shock me (pun intended), I do a lot of automotive wiring repairs. The switched ignition power wires in the GM harness are pink. And your friend is right, it is an alternator.

Some might make a quip, but we're here to help. I think a big part of being a Fiero owner is that most of us enjoy (love) a challenge. As long as it's not a front manifold bolt, eh?
Myself, I've pulled enough dashes (and have a parts car with the dash already pulled, for reference) to have a good grasp on what wires can be found in their respective locations.
I am taking it slow and easy. I learned early on that the labels don't stick so well to the wires so I started to tie a granny not at the end of the wire so it would not slide off then end of the wire. .
