1989 Camaro - Voltage Gauge

It appears there is a loose/corroded connection somewhere in the volt gauge circuit. You'll hit a sharp bump and it will move up to it's normal position (just a hair over 13) and hit another bump and it will drop down to around 8-10. I was wondering where the wires connect for the volt gauge; so I can check for bad grounds or corroded connections.

Thanks in Advance!

Re: 1989 Camaro - Voltage Gauge

At the gauge end, I think there is a harness that plugs into the back, which is a printed circuit board. IRC.

Re: 1989 Camaro - Voltage Gauge

The whole instrument cluster presses into a circuit board of sort. If the guage is not working right, it may be the actual guage itself, or it may be somewhere beyond the circuit board. I call it a circuit board, but really it is more like a flat plastic sheath that has a bunch of thin copper pieces that mate with the back of the instrument cluster when you fit it in (kind of like how a car stereo detachable face plate mates to the stereo body). Unfortunately, I don't know where the wires go from this 'circuit board'. I am wondering if perhaps some of the other guages also malfunction when the volt meter acts up. When it goes wanky, does the oil pressure, temp guage, and fuel guage read false too? If so, this happened to me last month, and it turned out to be a fusible link that was operating only intermittently. Now, I don't know where this link is, I had a wiring guru at the speed shop trace the wires so I didn't have to risk an aneurism doing it myself, heh. It only ran me $80 all tolled, so it was well worth the trip to the pros.

Re: 1989 Camaro - Voltage Gauge

Well If you read my post over in heating & cooling on days when the gauge works normal; the oil pressure gauge also operates correctly.
When the volt gauge is sitting around 8; the oil gauge operates; but like on a lower 'scale'. For now I added a Radioshack 0-15V DC Voltmeter on that little ledge above the Heat and A/C controls; and the + wire goes to the IGN terminal in the fuse box and the - (ground) ties in to the radio's ground wire.

Re: 1989 Camaro - Voltage Gauge

Aingh, I dunno what to make of that... what does the volt meter read? If your volts are OK, then there is a slight chance that perhaps the copper contacts at the back of the instrument cluster arent' making a proper contact with the volt guage. A quick wipe with brake cleaner and some WD40 will clean 'em up, and you may need to bend some of the copper tangs out to be certain they mesh snugly with the cluster. Failing this, and your volt meter says 'ok', then I would suspect the actual voltage guage itself. Iwish I had my old cluster, I'd send you the V guage if I did.
