As I thought.
I keep getting a varied voltage reading after Pirkle has rebuilt the VR. I have sent it back to him twice the second time he found a loose resistor so I thought the problem was cured. Last night I installed got a 13 volt reading once, then a 16.6 then a 17-18 volt reading. The funny thing is that my amp gauge is steady not pulsating...the gauge looks like I have a normal charge scenario. I took the original one off and put the auto zone model back on and have a nice 14 volt reading with a good amp gauge reading. I don't know what to do. Any ideas other than calling Pirkle back.
I have a dated rebuilt original that has started to charge high, then discharge, then go neutral. I bought it somewhere else, but I hope Pirkle can fix it.
By the way, the gauge is a mili-volt meter, not an ammeter. It measures the drop on a wire between the terminal block and the horn relay. I thought that was interesting.
