This is a warrantee issue that Jayco will cover if you have a newer unit like mine...I just don't want to wait the 2 plus weeks it takes to get in there. He said also breaker can be purchased at an auto supply store and is a 20amp.
So I actually went to the parts store and bought two new ones. One for the Lippert Sway Command (the one that I posted a picture of yesterday) and the other for the Tongue Jack (also a 20A breaker, inside the tongue jack box). I replaced them both this morning and still nothing...
I also inspected the negative line and where it mounts to the frame. Having the enclosed underbelly added 5 minutes to the job (Haha). Attached is the picture of the ground mounting. Wonder if I should remvoe and grind down a little bit of paint to ensure that it has good contact?
Otherwise, I'm at a loss on this issue now. Can't really see any fuses on the wiring and I went back to the converter inside the trailer and all the fuses pass.
