Hot Water Heater

First, I would suggest you abandon the idea of a tankless heater. There may be one on the market that is usable by RV'ers but there are a lot of complaints from those with tankless heaters.

Can you post the name and model of your water heater? It will simplify and get better advice from members. Since you have a wire that has the jacket melted, you should not try to operate the heater until that is repaired. If it was mine, I'd trip the breaker that powers it.

Need to find the root cause of the wire melting. Maybe a mobile repair person can help you.

Atwood units (which I believe you have) use brown, blue and green. Brown is +12 volt from the switch, blue is a return line from the heater (ignition control module, a.k.a. board) to a fault light, and green is ground.
I have the service manual on my service manual page, and the owners manual on my owners manual page.

Probably melted from a bad/loose connection.

Thank you for the links and the information, It is an Atwood and the links will be a great help, I really, really appreciate them.

tankless are great you just have to wire them seperate. you can take showers as long as you want bosch has one that does 110v or 220v. For what you can buy a new water heater for now up grade to a 10 gal.

The one I located uses propane so I do not have to run new wiring for 110v.
