Now that you mention it I had a voltage regulator go bad towards the end of last year and I had no choice but to drive it for a mile or so with ammeter bouncing between normal and pegged before I could pull over and disconnect the alternator and drive home on the battery. I thought I was ok but apparently the damage was done. Not a problem pulling the dash in fact I already have the corner switch bezel out looking for pinched wires so only about 8 more screws and the cluster will be out and I can check the connections then and decide my next move which for now may be just running a new wire beside the old one instead of splicing in a piece.
