Running light problem

[tradmer1]

Hello. I have a 2026 Jayco Greyhawk 29mv. I scraped the rear on a gravel driveway and scraped up the wires leading to the trailer connection. I assume I blew a fuse because I have no tail lights, brake lights, directional lights or side marker lights. I assume I blew a fuse from the scraped bare wires. Can anyone tell me what fuse it is? I've looked through the manual and I can't find anything for the tail lights! Help!

There must be one in the engine compartment fuse box or under the dash which are often labeled at the box.

Chances are one of the wires is broken, such as a ground wire.

There is a factory ford fuse box under the hood. On a non stretched chassis the trailer wiring harness has it's own set of fuses. One fuse for each function. I would assume on a stretched chassis it's wired the same, as long as the hitch came with the unit.

Do double check for any broken wires and fix them.

It's possible you don't even need a fuse. If you chopped your ground wire (usually white) in half that would cause all the lights to fail. When your inspecting your wires, keep in mind that the wire may be severed but still being held together by the insulation. A 12V test light with an insulation piercing probe, readily available at an auto parts store, is your friend for this sort of thing.

Here is a link to all the fuse locations on the E450.
