Also, obvioulsy I know the microwave and AC wouldn't run off the battery but should all the inside lights, radio, pump, and fridge (with LP gas) work off the battery correct?
Thanks in advance.
Red is positive, white is negative at the battery. If you trace the 10 gauge white wire, it should be connected direct to the frame at some point. That is ground. For some reason, in many RV's white is ground in place of black.
HOWEVER, some appliances installed in RV's may use the more traditional red and black so care is important.
Interior/Exterior lighting, radio, pump, half the fridge (other half uses 110vac in most rigs), vent over the stove, and the control circuit for the hot water heater are all 12vdc.
Some of the convertors can run the trailer without the battery installed, and some can not. Regardless of which you have, it is always a good idea to have the battery installed and operational to protect the system while in use.
