My amp gauge on my 14,000 '72 Pantera started pegging out at +75 amps. Bought a new one from Mike Drew. Upon pulling the dash to remove the old gauge, I see that the amp gauge (both old and new) have two terminals marked "+" and "-". But, on my car, the gauge in there now (which was working when I first bought the car) has a black wire hooked to the "+" and a red wire to the "-", which seems counterintuitive. Is this correct?
