Forum Discussion
This post has drifted off topic a little bit to a "problems with connecting a running tow vehicle to a fifth wheel hooked to shore power" discussion.
I'll take up that one first. My 2005 Ram would occasionally blow the truck fuse on the 12V power to the trailer through the umbilical circuit. It seemed to coincide with running attached to both shore and truck, but not every time. I read somewhere, perhaps in owners manual, perhaps here, perhaps a technician told me, that this might happen. My newer RAM does not seem to have this problem and I have tested it inadvertently.
By the way, if the original poster says his truck lights are working and not his trailer's, then I do not see the need to check his truck fuses. As others have said, it looks like a connecting pin or umbilical cord problem to me.
