Alright help me figure this out. I have my Autometer EGT guage mounted above the heater controls where the vents were. If Im driving with no accesories on its fine. But if I have my lights on and I turn my heater blower on, it jumps everywhere. Same thing happens if I have my tunes cranked and I hit the brakes.
Now I know its a voltage problem. I thought I corrected it by running the main power wire into the acc. wire on the ignition, didnt work.
So what do you guys think? Could I run the power wire directly to the battery? Would it use enough voltage to kill the battery, or any other ideas would be greatly appreciated.

Well, I grounded it to the chasis and its still doing it. Is it possible that its doin it because I have Corbins A/F meter and the EGT's power wires and grouond wires spliced in with each other?
