Fireplace and electric hot water heater not working
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?
