Water Heater Wiring???

GKopecky1971 · 04-30-2011, 07:20 PM

Alright, really confused right now. Have new water heater, and it is gas/electric with DSI. Encountered a few problems, and I could really use some help...

1. Wires on water heater (12V Side) are orange, green, blue, and white. According to wiring diagram from Atwood, I know where these are supposed to hook up. Problem: Wires from travel trailer are red, yellow, black, and white. Am I going to have to trace each wire and figure out which is which, or does anyone have an idea of the correct hook-up?

2. Wires at switch for 120V...switch is off but power at end of wires is still live...knocked the mess out of me. Had to turn off breaker before juice was killed. Shouldn't the 120V be dead if the remote switch is off?:lightning: I'm going to have to take the panel off of the wall and figure this out unless somebody here can help me out.

In short, I would appreciate any help y'all can give! Unemployed, so I can't afford to take it to a dealer. I don't wanna have to tear the walls out to trace wires, but don't know how else to figure out what's been done to my new baby.

George,

I'm presently camping, so I went out to check my wiring but it was a little tough with a flashlight (it's 10PM), but it looks like the 12V TT wiring on my 2005 Jayco unit plugs dirctly into my Atwood HW. I will take another look tomorrow.

If you don't hear back from me tomorrow, I would contact a local Jayco dealer to see if they have a wiring schematic for your year/model, if not contact Jayco directly Monday AM at: 574-825-5861, ask for Tony Bontrager in customer service and explain your situation. Have your VIN ready and they will find a way to get you the information you need.

Ok, I am on slow Internet so can't send pic....I have orange, red, white and blue coming to my water heater...all the colors match except red - which connects to blue...Yours may be different model while is why the colors don't match. If you don't have the service manual, see my signature fornthe link.

You will always have your 120 volt hot....the wires you see coming to it are 12 volt and just trigger the relays. You should be able to easily pop off your main control panel for the water heater and see which wires are gas and which are electric.

Remember that trailer wiring is different and it really threw me when I first started working on them. Black is usually 12 volt positive and white is 12 volt negative. You should be able to validate the wiring by using your multimeter and having someone flip the switches inside.

Hope that helps.

You guys rock!!! Gonna head out first thing in the morning with the wifey, because she likes flipping switches. Really wasn't sure about the 110V always being hot...thought it was like a house...flip the switch and the power is either on or off. Have a lot to learn about TT's, but really looking foward to it, and meeting great people like y'all. Again, thanx a million, y'all are life savers!!!

Same situation here. My location in the Campground is such that the WI-FI signal strength varies all day. Right now I'm at 1.0Mbps, nope make that 2.0Mbps with signal strength.....Very Low!

I am on Edge with AT&T, barely useable so sorry if I am a little choppy on my response.
After looking at the service manual, I think the wiring from the heater is:

Orange - gas
white - electric
Green - (-12v)
Blue - lockout light

Does that match what you thought?

I would recommend you just pop off your stat panel. There is a little tab on the top you pry with a screwdriver. Then there are 4 screws that hold it on. You should be able to get a good view of the wires on each switch and the light. Then do a quick test with your multimeter to validate and you should be good.

You will really like that dsi water heater. Starts easy...and you can run both elec and gas at the same time if you need hot water fast when you need multiple showers.

George - how goes it? Did you get it figured out?

Yeah, thanks for all the help! Took the panel off of the wall like you suggested, and talk about a spaghetti bowl of wires!!! Spent an hour tracing everything down, because the wires on the back of the panel didn't match what was coming into the WH compartment...some after market guru must have messed around with it. Finally tracked everything down though, and washed my hands with HOT water for the first time in the TT! Talk about a great feeling!!! So excited think I'm gonna sleep out there tonight! Thanks again for y'alls help, and God bless!
