Sparking 12v Socket

We had Newmar install an additional 12v socket in front of the copilot seat for GPS etc. We've used it successfully over the past two years. This weekend, I plugged in a portable Sirius/XM system, for the first time, I think, and got sparks and a blown 20 amp fuse. After replacing the fuse, I tried again and got another blown fuse. When I replaced that fuse, I got sparking from the fuse blades. The fuse did not blow. I went back in the coach and plugged a 12v fan into the socket without a problem. This sparking isn't normal, is it? And if it isn't, what the heck is going on?

Note: I did tempt fate and plug the Sirius jack into another custom 12v socket at the driver's end of the dash without sparks and it did run the Sirius system.

Thanks again to all the knowledgeable folks on the forum for your help.

You'll need to have the wiring checked for that outlet. I'd leave the fuse out for the time being until someone can look at it for you. I suspect you don't have the electrical knowledge to repair it yourself.
