volt guage says 11.8-12.4 scan guage says 14-14.2
Either at highway speed or idle my voltage guage in the dash says 11.8 to 12.4 volts and my scan guage says 14 - 14.2 when this low voltage happens. So far nothing seems to be affected by this. I guess it might be a bad ground wire to the cab but that's just a guess. Does anyone have any advice or experienced this before. The truck is a 2003 freightliner Columbia with a Detroit 12.7
Is this a good question?
