My O'Day 272LE has a GUEST 2615M 15 AMP on-board charger that appears to be original equipment. I think it has died. Shore power checks out fine through the AC plugs, but the meter on the charger registers no charge current, and the batteries are apparently not charging. I have looked at several GUEST Marine distributors web sites and I cannot find this model for a replacement. I only see chargers that apparently are designed for fishing trolling motors with no meter. Can anyone recommend a good replacement for this unit?
