Marker lights out!
I have a 2016 Jayco Eagle 321RSTS 5th wheel towed by a 2017 Ram 3500 DRW and Anderson Hitch. With the trailer unhitched the marker lights work perfect. When I lower the kingpin onto the hitch with full weight on the truck, the trailer marker lights short out and blow the fuse on the truck. I have verified this by using a 20A blade fuse to jump the marker light pin and 12V+ pin on the trailer 7-pin plug then hitching up. The fuse blows immediately. Seems to be a wire in the front cap area that shorts out when the frame flexes slightly during hookup. Anyone had a similar issue? The coach has all LED lights. Thanks!
