12-VOLT DC SYSTEM
The majority of your recreation vehicle lighting is powered by 12-volt electricity. The 12-
volt DC system is composed of components that will operate when the following conditions
are met:
Power is supplied by the tow vehicle alternator when the engine is running and the
7-way trailer plug is connected. This powers the RV’s running lights, brake lights, turn
signals and brakes. In addition, the 7-way trailer plug provides a common ground and
a 12-volt charge line to charge the auxiliary battery.
The converter will supply interior 12-volt DC power when the power cord is plugged
into campground power. The converter will also charge the RV battery in most
situations. (Refer also to the Battery Disconnect section)
The auxiliary battery powers many interior 12-volt components including the lighting
