Got a quick question

My 26rr with electric jack is currently stored at a family members home not plugged in. The battery has drained down and no power to jack. Will I need to plug it in to power to be able to pick it up or will plugging it into towing vehicle provide power to jack?

the tow vehicle should provide 12 volt power. Key word being "should".

Yes it should be able to power the jacks, but you should have a charged battery before towing. That is what powers your brakes if the trailer separates and the break away switch is pulled. Not good for a battery to be allowed to die either, it will shorten its life or end it.

the 12V line in the Bergman connector should power the winch if battery is just little low. If the TT battery is dead, and you connect TT to TV there is a good chance that you will blow the fuse in the TV as the TV will see very high load. I would charge the TT battery first by either connecting it power or taking it home.

To the OP, to help clarify:

Not all trucks supply power right from the factory. My Ram did, my brother's Ford needed a Relay installed. Can't speak for GM, neither of us have one.

You should have a tool that came with TT to raise jack manually.

My Chevy does supply power. Not sure if it will be enough to lift yours if really dead though.

A battery tender would be a good option to have. Either connect it at site if possible or remove the battery, bring it home and then trickle charge it until needed the next time. The latter is what I do. Works great!

As an addendum somewhat: You have parasitic battery draws from the CO detector, digital displays like on the radio, etc. These will drain a battery when not plugged into a form of shore power that recharges your battery thru the converter.

To help with this, you can install a battery cutoff switch, or disconnect the negative terminal from your battery when storing.

Hey wmtire - what is the reason for disconnecting the negative wire vs the positive?
