Thor Electrical Issues

[Doodles]

I am a new member. My husband and I have a Thor Four Winds 28 ft. We are having issues with our coach. When we unhook from shore power our fridge check light keeps beeping irrratically,(propane is turned on and full) the radio flickers on and off and the smoke detector beeps on and off. We think it seems like a loose battery wire. Has anyone had this issue? Where would you start checking?

Not real familiar with your coach but sounds like low/no 12v power. It takes 12v for fridge to switch to propane. Do you have house batteries, if so how old?

Thank you for your quick reply. We just bought the coach in november 2021. We dont think it would be that old. It seems like a loose wire or connection since the battery flickers on and off. We are going to check the terminal connection when we stop but thought maybe I would check with others to see if they had similar issues

Very good to know about the voltage needed to switch from electrical to propane.
