Expert Reply:
The Electric A-Frame Tongue Jack # JET-3555 grounds through the mounting bracket of the jack. If your trailer isn't hooked up to your tow vehicle when you are trying to use the jack the problem would be that it isn't grounding properly. If you run the ground of your trailer battery to the trailer frame it should work.
