Re: Battery gauge dancing while lites join in (1313)
Earlier this month while I was in a Christmas parade my '75 started doing the same thing. I prayed the car would make it through the day before crappin' out. It did.
The next day I took the easy way out and replaced the alternator. Problem fixed. You could have one of a myriad of issues in your electrical system. I got lucky with an easy fix. :yesnod:

Re: Battery gauge dancing while lites join in (1313)
The lights will dim as the battery current is drawn to the short circuit in the electrical system. It could very well be an alternator/regulator issue or a short in the wiring. I'd test the alternator first since it's a free test at your auto parts store.

Sounds like a loose ground. Unfortunately there are a lot of grounds on the car. Check the ground wire running to the alternator. There's also a bundle of ground wires at the front of the center console including a ground wire for the gauges and interior lights.

thanks for the help so far... the gauge is bouncing to the positive side only.
interior lites, dash lites all flicker with the gauge
