We have a Trace inverter with battery charger model #U2512SB. It is feeding back power to the slip pedistal. When battery charger is turned off, all is good. The inverter had a relay switch that when power cord is unplugged the inverter comes on. When the feedback reading from the power cord pedistal end was done it was plugged into the boat! Could this be caused by the battery charger? Or possibly a bad relay switch.? I do know one thing, this is a dangerous situation. Not sure how long this has been going on, it was found by accident by maintenance crew who noticed our pedistal box was hot.
