Blown Jack Fuse I have a 2020 MPG camper and we were camping for a week and when we went to hook up to the truck to tow home the fuse blew. We replaced the fuse and then within 2-3 seconds of pushing the down button it blew again. We replaced about 5 fuses and it kept happening so we had to crank it down manually. Any ideas what could be causing this to happen? It has never happened to us before. Re: Tongue Jack Blowing Fuses I have had my camper for 4 years now and have never had a problem. However we were just camping and when we were hooking up to leave and pushed the button to lower the jack the fuse blew. We replaced the fuse and it happened within 2 seconds of hitting the lowering button. Replaced with last of fuses we had and did exact same thing. So we had to use the manual crank to get it down and also then when we got home same thing and had to crank up with the manual tool. Any ideas what could be causing this? It has never happened before.
