Electrical Issue in Gauges?
I have a 2001 Monaco Dynasty 40 foot motor home and whenever I pull the headlights "on" control out (on setting), most, if not all, of the engine gauges on the dash changes (increase in value). It’s weird how the engine tachometer, engine temp, trans temp, alternator, engine oil pressure, etc. all increase in value whenever the headlights are turned on, and decrease in value whenever I turn the headlights off. Obviously this is an electrical issue, but what is the electrical issue?
Has anyone experienced this before? My first thought is a ground issue, but where?
Thanks,
Bill
