Hey gang, long time.....

Two years ago I rebuilt the voltage regulator in my rallye dash with solid state guts. My dead fuel gauge came back to life, and I was happy.......

Last summer, I noticed when I had my lights on, the fuel gauge would peg past full. A bit of fiddling and I found out it was directly related to the dash lights-dim the lights, the fuel gauge went back to normal. Turn 'em up, fuel gauge peg.

With spring looming, I'm working up the courage to pull the dash and poke around looking for what's causing this.

I welcome any hints, tips or past experiences that might guide me in figuring this out.

The older I get, the less I enjoy being upside-down under a dash having 40 year old insulation, dust and God-knows-what-else falling in my eyes.....
