We have a 1993 Fleetwood Southwind RV. We are replacing the Atwood G6A-7E with a G6A-8E. The new water heater wires are Brown, Green and Blue but the RV wiring to the switch are Red White and Blue. Need help figuring out which wire goes to which?
Hi: Thank you for coming to Just Answer with your question. My name is XXXXX XXXXX perhaps I can assist you with this issue.Go and CLICK HERE for a copy of the Atwood Service Manual for this model. There are wiring diagrams in there. On this one the red and brown go together. White and green go together. Blue goes to blue. The red is positive, the white is negative and the blue is for the ignition lockout lamp. You can use butt splices or wire nuts to attach these and then tape them with some electrical tape. I hope that is helpful. Please get back to me if you need more on this later as all follow ups are included in our fee. No limit as to time or number or responses. Positive Feedback would be greatly appreciated as that is how we are rated and paid.

Actually the white wire in the RV has a red stripe, does it still go to the Green wire on the Water Heater
It should but the safest way is to test this with a small multimeter. That is not a standard color. Some of these manufactures stray from using standard colors that are accepted in the industry. If you have a small multimeter like you can find at most automotive or hardware stores for about $15 you can take a DC volts reading between the red and the white w/red and see if that gives you a positive 12 DCV reading. If the minus sign shows on the screen the polarity is reversed and someone wired it badly. If I was doing this and didn't write down the colors when I removed the old one that is how I would check it. A multimeter is very helpful to have for any kind of diagnosis on these coaches. We do this all the time to check this sort of thing.
