Just spoke with a tech at Painless. They advise against using the stock ammeter, as it's 40 year old technology. I understand their reasoning, but I was hoping to have all my gauges functioning. They suggested the use of an aftermarket voltmeter. They also advised that there may be some company or individual that converts the ammeters to voltmeters. I'm sure this is expensive, but I would consider this if it wouldn't break the bank.

Anybody have any tips or suggestions?
