I had converted my 70 GS beater to instrument gauges from the basic fuel gauge. I re-pinned the connector as per George's site. But now on start up, the temp gauge spikes. You can actually hear the needle bang on high. On my car, its just the temp gauge I just converted Stacy's GS to gauges and his does the same thing. Now, on George's site, he says to cut the green wire off the ignition switch to prevent this. So I located the wire which is a green 14 gauge wire and cut it. But the gauge on his car still spikes. What is the fix for this? Or did I cut the wrong wire? ou:
"Disconnect the dark green wire at the ignition switch on the lower column" Sounds like you cut the green wire in the harness.
Are there two green wires that are 14 gauge coming out of the switch? I didn't see another one but now Im second guessing myself. I have to go look again or look at the schemaic
You said you located the green wire and cut it. I was not clear where you cut the wire. Was it at the ignition switch?
Jason...here's some Olds info....there's more about the pegging....I'll look for it. http://classicoldsmobile.com/forums/electrical/92405-rally-pack-temp-gauge-wiring.html
More...still not the one I'm looking for, but it's fun to be confused, huh? http://classicoldsmobile.com/forums/electrical/53968-1973-cutlass-442-rally-pack.html
I used Georges info to switch the pins on my car and I didn't cut any wire(s). It all seems to work fine. I did add another ground from the instrument panel to the body just to be sure everything is properly grounded.
I actually got to the bottom of the issue with Stacy's car- A little bit of miscommunication. I never saw the issue myself. It got late and I never tested the cluster after I installed it. We were going back and forth with texts the next day. It was only after actually speaking to him on the phone we got the bottom of it. Issue resolved. The gauge wasn't banging on high, the wire was just off the sender. Now to clip the green wire on my beater GS and see if that cures the gauge issue
On my tan GS with the triple gauge conversion, when you turn the key to the on position, the temp gauge bangs on high. Its actually audible. The green wire coming off the ignition switch sends 12v to test the temp light on start up with a regular fuel gauge. Clipping it prevents the 12v spike to the rally temp guage.
So the gage doesn't stay pegged? It just spikes momentarily? I bet mine does that and I never noticed. My eye is usually on the OP gage on start up.
George Nenadovich has another great website with Buick related articles where each will have multiple 8-by-10 color glossy pictures with circles and arrows and a paragraph ..... explaining what each one was to be used as or how to install. Here is his site link. http://www.buickperformanceclub.com/page1.htm Troy
Carefu on cutting the green wire. I probabmy misread George's post, but i cut the green wire coming out of thr column and then my rear turn signal didnt work....haha...
