I originally posted a help topic on my tach not functioning….but now I’ve realize something else may be the culprit.

I used to have some crazy buzzing noises coming from the back of the instrument cluster….and one day the tach finally quit. I figured this was an isolated issue…and that I simply needed a replacement. Well, I’ve now realized that my battery gauge is no longer functioning (voltage from the alt is fine) and my factory temp gauge get’s pegged. The low batter light also trips….and lights up ever so dim. I’m unsure if the fuel gauge has been affected yet, but I did recently run out of fuel…thinking I had more. The dash lights remain working fine however while all of this occurs.

Is there a check-list on possible causes for some of these issues?

Edit:

Ok, after a search it seems that this could possibly be a grounding issue. I wasn’t thinking this as the lights are still functioning as is the oil pressure gauge. I’ll check them tonight…but which ones in particular seem to be an issue?

Also, it seems there is a possibility the issue lies with the IP voltage regulator. Where is this located…and how do you diagnose?

I think Willys1 would have had one by now. If he didn't get banned. "Again"!

I may be having a problem similar to yours. When the car is running all the gauges will like drop down and the lights will all dim, happens about every 5 minutes or so. Also the car surges like power is lost. I've checked all th grounds and all look good? Idk
