  • I don't know about everyone else, but, I don't read posts without punctuation. Those long sentences make my head hurt.
  • thanks mister wizard I think your on the right track with high 12 volt current because this will happen more when I accelerate more than engine idling making the altenator charge more what is the cure for the problem can always wire in a stand alone 12 volt stand alone battery just for traveling when generator is on
  • Chances are we'd better understand what you're trying to say if you broke your post into logical sentences ... as it is, a post consisting of one long run on sentence is tough to decipher. Maybe MrWizard understands? :h
  • you have a voltage problem on the 12v control circuits
    generator on for A/C, converter is on and charging batteries
    engine running alternator is also charging batteries
    im guessing you have a higher voltage alternator than usual

    try un-plugging the converter, flipping off the CB for the converter
    this might reduce the 12v circuit voltage enough for things to operate normal
    if not you need to look into this voltage situation
