The power converter converts 120-volt AC power to useable 12-volt DC power when the shore power cord is connected to an external power source. The converter has a built-in protective thermal breaker that will shut it down should overheating occur. Overheating can be caused by operating the converter above its maximum power output for an extended period of time, or by an obstruction to its ventilation air flow. To reduce converter heat build keep unnecessary 12-volt lights and motors turned "off". Keep the converter cooling fins and fan clear of obstructions.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged) check the reverse polarity fuse(s) in the converter fuse panel. There are no customer serviceable parts inside the converter case and the manufacturer's warranty will be void if the case has been removed. If you have further concerns contact your dealer.
