had voltage issues when running down the road especially with AC and headlights on. Replaced with a new Powermaster alternator, added an extra 6 Gauge charging cable and ground. now at an idle she is seeing 13.8 volts with everything on. What a feeling.

replacement alt with extra ground lug and a proper threaded boss style power point.

Old alternator with stud type power port.

Good deal . It's nice when things work out right

I have low voltage from my stock 60-amp GM alternator when the heater fan is going or head lights, especially when the suspensions air compressor is running. Was just gonna stick in a standard GM 80- or 100-amp upgrade but maybe now I will go with this system...Thanks for the tip!!
