    Hi Tammy and Chad,

    Are you plugged into shore power when you try this? Is it all lights or just certain ones. Is the key on the battery disconnect all the way out?

    On my 337, the battery disconnect disconnects all power except to the front jacks I believe. The front light on the hitch may also work, but I have not tested that.

    We were told by JD that the battery disconnect switch doesn't completely disconnect the battery. If the trailer is left unattended for a few months, with the disconnect key removed, the battery(s) will discharge due to a draw from the trailer. The only way to completely disconnect the batteries is to unhook the cables or have a disconnect switch installed between the batteries and the wiring going to the trailer.

    Isn't that the purpose of a battery disconnect switch? To completely disconnect the battery? I'm not too familiar with them, but that sounds like a waste of time, material, and labor to partially disconnect.

    I agree. The battery disconnect should do exactly what it says. Disconnect the battery completely. My battery goes down relatively quickly with the disconnect key removed. I was thinking of putting a marine disconnect switch in the battery compartment.

    I'm thinking that the propane leak detector is required to be direct wired to the battery. I can't think of anything else that would be a continual draw while in storage.

    All that is required to fix this is change the wiring connection for the extra items from the battery to the outlet side of the disconnect switch that is already there. It is a little hard to describe, but there is a second wire attached either at the battery or at a connection point (like a circuit breaker) before the disconnect switch. Change that wire to the outlet of the disconnect switch. Then everything will turn off when the disconnect is turned off.

    I also believe that the landing gear can be used when the switch is turned off. I haven't verified it, but I'd rather it be switched off also. If you're RV is in storage, you sure don't want some joker being able to toggle the switch and move the landing gear up or down.

    Under the front cap on the 337 right above the battery behind a plastic cover are some binding posts. One is for ground wires, one for battery and one for switched battery. If you move all the wires except the battery feed to the switched battery post, the disconnect will kill all power to the 5er. I know on mine the landing gear in not switched. I don't know if there is anything else not switched or not.

    Make sure that switch is rated for the amp load. You would not want a fire! the switch looks cheap to me. I would add a better switch off the battery.
