Sometimes I really have to
So now, the cummins is HOT, the alt gauge still moves like molassess, BUT when I check the batteries for voltage they are holding 14.35 v...steady.
Headlights drop it a little to 14.15 v and blower motor drops it to 13.98 v with headlights.
I guess I have to drive it with headlights on and see if it charges enough to restart. The ALT GAUGE is making me paranoid..
