Power jack light blows fuse

[sdiersing]

I have a brand new 27BHS with the power tongue jack. The up and down function of the jack works fine, but the light on it blows the 30amp fuse. (It worked fine when we brought it home. Now it just blew 3 fuses in a row). Before I open the jack up, can anybody give me any clues of what I'm looking for?

Thanks.

For a small light like that to blow a fuse sounds like there's a direct short on the hot wire side, to ground, either from the connections to the light itself, or the switch that controls it. I'd take them apart (if possible) and make sure any power source isn't touching the casing, or a ground wire. Of course, you can eliminate all that by getting a new one under warranty!
