Darryl, I have run into this same problem before. The first time it was the on-board charger failed. While researching for a different charger, the 24 volt connection should be made at the plug-in at the trolling motor, not at the batteries. When recharging, the plug MUST be unpluged to remove the 24 volt connection. Since I have made the right connections I have not had any problems. :D The first charger was a Guest model. I'm now using a Cabela's model. You ,might call the manufacture of your charger to discuss this problem. You might disconnect the batteries except for the charger and see what happens. Hope this helps! <*)}}}><
