RV industry 12 volt wiring standard is: black = positive (+), white = negative (-). Remember in the RV chassis, there’s also black/white/green 120 volt AC “house” wiring (a third wiring “standard”).
What happens if you hook an RV battery up backwards?
The protection circuit shuts down 12 volt power to the converter/charger if you connect the battery “backwards” and even after you reconnect it properly, those fuses, being blown, won’t allow any 12 volt power from the battery to the 12 volt distribution panel until after they are replaced….

Does it matter which wire goes where on a lamp?
If you wonder why you have to identify and connect the hot and neutral wires correctly in a lamp, read on. True, the lamp will usually work either way. But the issue is safety. Normally, power (voltage) comes through the tab on the socket base.
How do you tell which wire is positive and black?
Place the prong of the multimeter’s red wire on the bare metal on the end of one of the black wires. Don’t get confused about using the red wire from the multimeter to test a hot black wire. The positive wire on a multimeter is red, and the black wire is negative.
Is the yellow or white wire positive?
Yellow is positive, blue is negative.
Can I plug in my camper without a battery?
Most things inside your RV will not work without a properly functioning 12-volt DC house battery system. … In order for your 12-volt DC house battery system to function, you need good batteries as well as a way to charge them. That is where your RV’s power converter is used.
What is a reverse polarity fuse?
When a battery is installed, two reverse-polarity fuses are installed to protect the converter circuitry. The fuses are located along the bottom edge of the DC fuse board near the VCC+ lug. … This feature prevents permanent damage to the converter from a battery connected into the circuit backwards.
