? jump TT Battery ?
Problem is I left my TT at the camp site buried in snow with a dead battery and no power.
Question= Can I hook-up jumper cables to the TT battery to operate slide and power tongue lift without issues. The seven pin connection does not seem to offer much power to the TT with TV at idle .I want to get my unit home tomorrow , while the weather cooperates.
Please any imput would be appreciated.

As long as your battery isn't frozen, I don't see why not . . .

Red to Red and Black to Black
To be safe, disconnect the cables from your TT battery and clip direct to the cables running into your trailer. I really don't think you'll have problems either way, but be safe and connect to the powering battery last so you are well out of the way should a problem occure.

Live and learn...IMHO lifting the cables from the dead battery would be eliminating the possibility of a frozen battery popping in your puss. And, if the TT dead battery is left connected, it'll be drawing down on the charging battery making for a more difficult slide retraction. It's best to disconnect the dead battery and use the good battery to pull in the slide, return home and give the dead TT battery a good charge. ~~ I think you could accomplish the task by leaving the dead battery connected but why take the chance of smoking the charging system of the charging battery and leaving you shivering in the cold wondering what to do next. Be safe.

thank you for the imput .. I will give it a try tomorrow morning.. I'll let you know how it goes...
It has been a long week with the more than 750,000 homes without power in the state (CT) and many roads still impassable due to downed trees and power lines.

just make sure to keep the jumper cables from touching each other while connected to your trailer especially if you are inside and no one is watching the battery cables.
Good Luck and make it back safe

Worse case you should be able to crank it in manually, right?
Also, remember driving home without a working TT battery your TT brakes won't engage in the event of a disconnect from the TV.

jumping the TT battery with the TV worked out very well . Slide pulled in with no hesitation also used the power tongue jack when it was jumped..in a pinch I think I coulsd run my furnace.
Thanks for all your imput.

 i would not advise jumping that dead battery with your rig if you cant put it on a trikle charger then at the very least pull it and check the outside casing to make shour its not bulging which could mean the plates would be sulferized an it is shot if it wont trikle then go buy a new one
