Electrical jack problem

[mjdsquad]

Hi - I hope you can help me with some insight into my problem. The electrical jack was recently replaced - wired it just as the previous jack was wired. The jack now only operates with house power connected to the trailer. It does not function on batteries only. I reviewed the electrical diagrams in the owner's manual, however they do not appear to address power to the jack. Ideas and suggestions are appreciated.

The electric jack is 12 volts. The ac power only charges the batteries to supply more dc voltage. Is it possible you have dead batteries?

Just a crazy thought

Hi, I agree with vlamica. If the batteries are dead or very weak, you need to plug into your tow vehicle or shore power to get your tongue jack to work. Also you might consider relocating the jack wires so they don't get pinched under your propane tank cover.
