While putting a back up camera on my 2002 Tiffin Allegro 30da (workhorse) I shorted the wires at the top center light. As you can guess it sparked and now no power to running lights or back tail lights. From my research I keep reading about an in-line fuse in the rear. Can someone show/tell me where it is. I’ve checked fuses under the front drivers side but nothing seems bad. Frustrating!
