Expert Reply:

Based on what you described, it sounds like a lack of power and is probably due to your trailer battery. If your 7-way is hooked up that would typically provide a maintenance charge for the battery. In this case it is more than likely just enough to let you power the jack with the trailer plugged into the vehicle.

I would start by making sure the battery is charged. It may also be worth checking the wiring connections just to be sure. If you find that you need a replacement battery you can use the # BRW34FR for a group 24 or # BRW94FR for a group 27.
