hwh leveling jacks just quit working

Hello everyone. First time posting. I have 610 leveling jacks system on my 96 Georgieboy that just quit working. We were at a campground and I was lowering jacks everything was working great. My phone rang and I stopped to answer, when I tried to start again the pump would not activate with the control panel. I got on the HWH site and started trouble shooting. Got it down to a bad control box. Replaced the box and still did not work. After replacing the box now it is blowing a 200amp fuseable link from the battery to the pump relay. Im kinda at a loss. Hopefully someone can help. Thanks for any help. It kind of sounds like a dead short to me but not sure. Could the pump motor cause this problem?

We had a similar problem, the pump just quit working but we didn't blow any fuses. It turned out to be a bad internal ground inside the motor, a fairly common problem.

If you remove the hot wire to the pump and activate the switch, does it still blow the fuse? If it still blows, then the problem is somewhere between the control panel and the motor.

Let us know what you find.

jacks quit

check the battery cable routing from the battery to the pump area, the only thing that will blow that big fuse is a direct short. this is normally a pinched cable or a bare worn spot on the battery cable. ive found this especially on coaches with slide out battery trays. pinched in the rear of the tray by the frame.

problem solved

Thanks guys for the advice. I removed cable from the motor and fuse did not blow. Checked for voltage at the motor cable and had 12 volts. Removed motor and checked all cable connections. Cleaned up the motor and tightened everything up and all works great. Thanks again for the guidance.
