no tail lights

[scottybee]

My tail lights are not working. Brake lights and turn signals are good.
Does anyone know where the fuse is for the tail lights?

scottybee-

According to the 2016 Ford F-53 chassis manual (link here), page 65, the fuse is #6 in the Power Distribution Box (PDB). It's a 20A fuse. The PDB is under the hood, attached to the firewall, about in the middle, above the radiator.

So the problem is a little different than I first described. When I turn on the coach lights whether in just the parking light position or full headlights on. I have no lights at the back of the coach. No tail lights no turn signals or brake lights. The marker lights on the side of the coach still work the front turn signals work the parking and headlights work. The instrument panel lights work also. But nothing on the back of the coach.
When the lights are off, the rear turn signals and brake lights work as normal and when the toad is connected the turn signals and brake lights work on both coach and toad.

I'm stumped any help will be greatly appreciated.
Thanks

scottybee-

I looked at the diagrams I have and postulate that there is a short inside the wiring at the rear.

Three places to look:

1) Coach trailer hitch connector. Open it up and see if the connections are OK and if there are any obvious shorts between wires inside it.

2) Coach rear light assemblies

3) Ford connections in the wiring to the rear. You usually find them somewhere within a few feet of the rear of the coach.

What happens when you turn on the hazard lights and then the parking lights?
