Group/List/Forum I finally got around to measuring the voltages across the pairs of batteries after a short run.... All measured 16.08 or there bouts....save those at the passenger end...those two pairs measured 16.35 and 16.38... I think that is telling me that one of both in the pairs have high resistance and are not taking a good charge?
