The brown spot on the OBC could be a sign of failure as well. If it is bad there are kits available to bypass the OBC and chargers that do not require an OBC to operate.

My recommendation is to get it checked out before your final decision as to cause and correction. Guess work could be costly and could not correct the problem.

Thanks for the advice. Had the batteries checked all o.k.. Charger works fine on my other cart so that pretty much leaves OBC.
