Opening Slides without Battery.

If the slide is hydraulic, there might be an access to the end of the motor shaft. Ours can be turned with a quarter inch hex drive chucked into a cordless drill. It is a little slow but much easier than cranking by hand.

You have 4 choices.

Provide power (120vac) for the converter (NOTE: may not work)

Lug the battery back out (Heavy) and put it back

Manual Slide operating (It's in the owner's manual bag)

And the one I'd suggest.. A good set of HEAVY DUTY jumper cables to connect the Tow Vehicle battery to the battery lead on the Trailer.

On the negative side connect to the trailer chassis or the metal part of the hitch and MAKE this connection LAST, (Break it first) when you hook up and unhook.

Take the battery back over to it.

Why not simply re install the battery. Do it properly or just use booster cables. Yes you can hand crank the slide but that will take all day. A drill might work but bring extra charged batteries for it.

How many wires were on the battery? My previous HTT had separate power leads for the slide, and the rest of the trailer 12V electrical. I had to tie the cables together to get the slide to run w/o a battery.

Since you have removed the battery raises a RED FLAG to me. Hope the terminals are not touching ground or each other when you add external DC power or connect to shore power without the trailer battery connected up..

I was going to suggest nosing the truck up close to where the battery goes and use JUMPER CABLES being direct connected to your truck battery,,,

You just have to watch the polarity of the cables and not blow some fuses if you get them REVERSED...

My slide handle was laying in the closet floor near the bedroom.

Plug the tail into the truck while running works for me

Generator.

You should have a handle. My TT has a handle that will operate the nose jack and the slide without power available. There should be about a 1" or so big hole on the opposite side of the trailer from the slide. Mine is just behind the step.
