    Question 12v Issues on a 1/3 of the 12v Fed devices.

    Interesting issue. 2021 297 RSTS, last year after storm discovered all 12v lights, awning, fridge etc did not work. I went to check the battery, dropped it, put it back up and everything worked again. I know funny right? This year, opened it up checked all 12v all worked. Storm rolls through, now Main over head lights, Awning and stabilizing jacks do not work. Fridge, Water Heater, stereo, etc all work. Pull fuses to the things not working, no light comes on at all, pull fuses to things that work, Red Light.

    Has anyone else experienced something like this?

    I appreciate it, Thanks

    It sounds like you have some loose connections in your 12v power center.

    Many people try to find problems with 12v power by checking that there is positive voltage getting to the device (in this case the fuse), however, I have found that most of my electrical gremlins happen on the negative side due to poor ground connections. Be sure you have good metal to metal contact where ever you have a ground connection.

    I bet if you pull out your power center (be sure your 120v is off and/or disconnected from the coach) and check all the connections/connectors you will find either loose connections or corrosion at the connection points.

    Good luck and let us know what the issue turns out to be.

    Thank you,

    I will check all connections. My thought was a ground somewhere, but the fact that some of the 12V is working kind of threw me off.

    Don't let that throw you off, they will use the most convenient place available to ground the return side of the circuit.....in other words, all the different stuff that is 12VDC in the trailer will be grounded in different locations throughout the trailer. I concur with the above responses about it likely being a ground issue somewhere, or even in multiple locations.

    On our Imagine there's a grounding bolt under the frame rail with multiple wires on it. Occasionally I remove the bolt, sand the ring terminals and frame, and use some electrical corrosion protector before reassembly.

    Tightening the Connections on the Bloc did the trick. I will hit them with spray on silicon so water can't cause an issue. Thanks for all the input

    Thank you. Yes I bought last July, I got 3 camps with it before I had to hide it for the winter here in MN.
