Kill switch for electric jack ?

just had a terrible thought,since i parked my a/s at a campground for a month,so g/f can use it on weekend's while i'm working,what if some curios type raises or lowers the jack when the bals are down? will the jack motor torque out ,blow a fuse
or my fear break the bal's and bend the frame? Is it possible to install a key switch in the lp tank cover, or is this asking for an explosion?

You could install a switch to cut power to the jack. The switch itself would not create a spark unless you flip the switch while the jack motor is in operation or if for some reason the switch contacts get contaminated. Mount the switch in something that would keep it out of the elements and you should have no problem.

Another way

The jack should be on a dedicated fuse or circuit breaker, whichever you happen to have. This is a good place to disable it.

Here is an sort of off topic question:

Since going out on two trips now, the old manual crank is kind of a bit much. I could deal with it, but I am kind of interested in installing a power jack on the tongue. Where would I get the power for such an install if I went that route?

Eric,

If you want to do it down and cheap just put a fused link off your battery post. That's where my old SOB had its jack powered from.

On the Safari I have a line which runs from the fuse panel to the jack.

Thanks Jack. I had figured that might be the answer, I just figured there might be something more eloquent like a wire run that is tucked away somewhere kind of like GM does. They ususally prewire everything and if you buy the toys, they just plug them in.

I may just do the off the battery bit since I don't feel like pulling cables from the mid of the coach to the front.

Eric

Eric, I use a spur off the blue power line to the breakaway switch, which is right where you want it. It is always live 12 volts, unless you turn off the battery kill switch, in my rig. Good luck. Nick.

If your trailer is set up on stands or the stabilizer jacks, (BAL) then the power jack will retract up into the sleeve and stop. Or the front end of the trailer will be raised a little. That is what the jack was designed to do .... raise the trailer. It will stop when it runs out of travel. It should not trip a breaker or blow a fuse. And someone could have fun raising and lowering your power jack and run down the battery.

Course you could just disconect the battery when you leave.

On your '03, the line for the power jack should be taped off in the vicinity of the jack. It is in the wiring harness whether you get the OEM jack or not.

Eric---We have a 02 Bambi & like you thought at first that we didn't need a power jack. we soon found out that it's a lot of cranking, so found an Atwood power unit on sale & snapped it up. Took about a half hour to install & I found that A/S has a prewire at the tounge location ( it's a dead end wire in the bundle ) ready for your power jack connection. For our unit I think it is a 20a fuse # 5 in the12 v box under the RS seat.. Our fuse at the box was not labeled other than extra, however the owners manual shows that this is the fuse for the power jack. since we installed the power jack the wife hasn't complained a bit when it comes raising or lowering The Rig. Hope this helps.
Best,
