I'm looking for some kind of power tool I can use to make my electric jack work when my batteries are dead.

My husband moved the LQ trailer so we could hook it up to the electricity and charge up the batteries since we had it parked for sometime in a place we don't usually keep it.  I don't quite understand all that happened and am not in the mood to ask him all the necessary questions, but from what I can tell he hooked the trailer up to the truck then brought it to where we hook it up to the electricity and then the batteries weren't charged enough and he couldn't unhook it from the truck using the electric jack.  He needed the truck to get to work the next morning.  He let it charge all night then went out this morning and all  @#$%^&*^*%&$% broke loose and all I heard was we were selling the #&*%*#@ trailer and somehow it all became my fault,  that is everything from skyrocketing fuel prices, the malfunctioning jack and the continuation of wars in the MIddle East.  After he took the clunker truck to work, I went in the trailer checked the charge on the batteries and went out and pressed the "up" button and it took awhile but the trailer raised up off the ball just like it should .  It did act if it was a bit hung up at first.

Without do much of a smug look on my face, I drove the truck in to help him inject turkeys for the hospital fundraiser.

He took everything out of the manger storage area to find the crank arm for the trailer jack only to find there's no way to hook it on.  So since we can't use the crank arm, what can we use, power tool wise, that we could hook up to the generator or run off a battery pack to make the electric jack work or crank up the electric jack without electricity.  Again, we see no way to put the hand crank on there in this type of a crisis situation.  

Also, since this looks like a new responsibility for me, can you tell me how I should clean or oil this electric jack so maybe it doesn't stick as hubby claims it did this morning?  Do I wash or grease the jack stand or oil any other riggings on it?

Thanks       

It could have stuck, It was probley a dead battery though. It takes a little amperage to get the motor to move. I am assuming that the batteries got enough charge to make the motor move after your hubby blew his fuse. If you can isolate the wires going to the control box for the jack(should be 2 wires) you could cut them, install a connector(male/female) then also make a connector for your battery pack and bingo you would then be able to use  your battery pack to raise the jack. Then reconnect the jack to the LQ batteries after they have charged. I hope I didn't make that to confusing.

Try that for the connector, $5 you will need 2 of them for the trailer and one for the battery pack.

Attach these to your batteries...then they'll always be ready...

Thank you all, this is very, very helpful.

Now my other question was, are there parts on the jack or the jack motor that need to be kept cleaned or periodically oiled?  Does the jack itself, the part that goes up and down, need to be oiled or kept free of dirt?  Ours looks dirty.

As a stallion owner, I could explain the parts I am refering to in a more biological fashion but I realize this is a family and not a reproduction related website, so I hope I explained myself adequately.

Could my electric jack have a "bean"?  

Something like this, http://www.asedeals.com/jumpstarters2.html

and you could also jump your truck if it ever needed it.

Good question, No when I went out to "fix the problem" the trailer was not plugged into the truck.

I'll check on this!
