It sounds like the switch on your electric tongue jack might have been damaged as well when the fuse blew. You can test this by simply bypassing the switch and connecting the wires directly to your power source. There will be one power wire to the motor to extend the jack and another one to retract. Also make sure you connect the ground wire to the frame. This will let you know if just the switch is bad or if there is something going on with the jack itself.

We do have a nice selection of replacement switches available. If you can tell me what model trailer jack you have I will be happy to see if we have one that will work.
