Gauge issue

I have an issue with my gauge cluster. My temp, and oil pressure gauges are pegging out on the high side. The gas gauge doesn't work, and hasnt for a couple years so I bought an aftermarket gas gauge. It works just fine. Here recently whenever I turn the key on the temp gauge pegs out on the high side. When I start the Bronco the oil pressure gauge pegs out on the high side, and when running the ALT gauge bounces slow at idle and erratic at higher rpm. I am hoping someone has had a similar experience, or any advise for a remedy.

Thanks in advance

Mike

You either have a bad cluster ground or it could also be a bad instrument voltage regulator.
