    Hi there,

    I own a 2010 FM and have just recently started hearing an arcing noise coming from somewhere in the fuse box. It's only happening when I go over bumps and i can't figure out what's doing it.

    I've taken the tray out with all the fuses and relays on it and pushed all plugs/Cables in as it sounds like a loose connection but that hasn't helped.

    Any suggestions would be greatly appreciated.

    Could possibly be a loose lug on the back of the fuse panel. I had that happen to me once in a Freightliner Columbia. Got bad enough the truck would just shut off and have to call mechanic to come out and fix it, until they finally found it was the loose lug on the fuse panel.
