I have 2003 Roadtrek 200 popular which I think has a alternator gremlin hideing under the hood, that is toying with me. It is Chevrolet 3500, 5.7L platform. My voltage meter shows no charge and the battery warning light comes on, then goes off, then on, voltage has been checked at new battery and alternator is new, this AM no charge /light, went 1 mile now charging/ no light on OK. This seems to happen when moisure in present, I'am grabbing at straws. Any gremlin exterminators out there.
