Battery Disconnect Question

My new TT has a battery disconnect. When I turn it off, the electric stabilizer jacks and the tongue jack still work. Is this normal? I thought it was supposed to kill power to everything.
  • That is normal. The only battery disconnect that will kill all power, would have to be installed right at the battery cable connections.

  • That’s how it works on mine. I only have an electric tongue jack and it is on its own fuse and comes straight off the battery. Everything else goes through the cut off switch then to the 12v distribution panel.

    Both of those pull a lot of current, and, they don't have a phantom draw. For those reasons, they are direct wired to the battery. Although you didn't mention it, the breakaway brakes SHOULD also be direct wired to the battery. The reason for the disconnect switch is to stop phantom draws from things like the television instant-on function, the radio with its preset channels memory, etc.
