Gauges go to full tilt!?!

Rusty, 66 is still internal. Not sure when it was changed.

I removed the IVR and installed a digital regulator. It sorta works now, but I have an aftermarket sending unit so the fuel gauge is off.

Edit:. Just saw he posted it has a new dash voltage regulator. Maybe it's bad.

Oh is it still in the fuel gauge? I THOUGHT they changed to the plug in style in 65. 64 is actually INSIDE the fuel gauge. You have to take the fuel gauge out and disassemble it. The fuel gauge is on one side and the voltage regulator is on the other. I was thinking they changed that to the plug in style on the back of the circuit board for 65 and up.
