Fireplace and electric hot water heater not working

[CanadaDave]

I have a 2014 Crossroads Sunset Trail Reserve 26BH. I hooked the battery up incorrectly this spring and blew some fuses. Everything is back online with the exception of the electric hot water and fireplace. I have power coming out of the breaker and I have power coming out of the 12V switch to switch from water heater to fireplace. There must be a relay in the 110 wiring somewhere however, Crossroads will not give me that information. Can anyone help with location or ideas?

Thanks,
Dave

Pull the fireplace, it should have its own fuse. The hot water heater also has a mini fuse on it and or a reset button depending on the model.

In our cruiser there is a switch on the wall to switch between the fireplace and hot water heater. Do you have one? Both are off when it is in the middle position.

On ours there is a switch in the control panel and also 1 in the dump station for the hot water heater. They both need to be on. Yours may have this as well
