Ignore wire color, there are too many "standards," and none of them are standard. Trace BOTH wires from the battery. ONE of them should go to the frame. THAT is the negative cable.

I have never, ever, seen a negative cable with a fuse or circuit breaker on it. I would bet money that the cable withOUT the fuse or circuit breaker is your negative cable.

Best advice I've seen in this thread. I do not trust colors in RV's cause they are wired by ELECTRICIANS not AUTOMOTIVE technicians or Electronic Technicians (I'm cross trained so I know both Traditions but THERE IS NO STANDARD!!!)


Home is where I park it.

I agree except that they are wired by folks that have no electricity in their own homes. [emoticon]

Most of them do have electricity at home, and it is more similar to RV wiring than conventional wiring. 12V systems with solar or wind are very common among the Amish. I installed or helped with several systems based on cheap automotive headlight bulbs before LEDs became an option. They did a good job wiring, but didn’t get the idea about voltage drop so tended to overload circuits and get dim lights.

You hooked the battery up wrong and blew the reverse polarity fuses on the converter thus no power from the converter. Most likely did damage to other appliances too. You are lucky if you didn’t blow the furnace, water heater, and refrigerator circuit boards too.
