Power jack

[Kamikaze]

If your power tongue jack either quits working or you’re battery is dead, is there a way to manually lift and lower it?

Your jack should have come with a crank that inserts in the hole on the top of the unit. You can also use a socket wrench with an extension and the proper socket, but that will take forever.

This. Oh, and even with the crank, it will take forever. Ask me how I know!! (Okay, I'll tell you...I backed into my power jack and broke the motor. I had to use the manual crank. It took forever!)

Yep, it'll take forever, but you'll get there. I ran my jack into upper limit and blew the fuse. With no spare fuse, I had to use the hand crank. Decided to change the fuse to a circuit breaker in case that happens again. Mark the lower extension with black tape (or something of your choice) so you know when you're close to a the upper or lower limit.

I just installed my electric jack and it has a rubber top cover or plug that is where the jack handle for manual use would be inserted. I actually pulled that plug and simply used my electric drill with the right size socket attached to it and it lifted the trailer up and down very easily. On my E-Pro 19FD, it takes about 100 cranks to manually life the RV to full extension. Not a fun task if you have arthritis as I have. The electric tongue jack is a real blessing for me.
When tying it into your batteries though, be sure to put the one positive lead onto the battery with the least amount of cables attached to the lugs, as you want to evenly distribute the load for each battery to lessen any chance of your batteries eventually playing out one before the other. I used extra long and extra heavy zip ties from Lowe's to keep that positive wire from dangling below the hitch area.
