So everything was working really good today I have the volts up on the cluster and there were ready 13.7-13.9. All the sudden the blower motor turns on full blast and my volts drop down to 12.2..... I had the final stage unit just hanging from under the dash, I try to unplug and it is really really Hottt!!! I pull over and unplug it and my volts go back to normal. Wtf
