Clearance/Tail Lights Not Working
We have a 2008 Winnebago View 24H and we're on the road this week. The 5 red lights along the top rear of the RV - clearance/tail or lamps (or running lights) are not lighting. I believe they are su...

This Link takes you to a .pdf of the body (house) wiring diagrams, page after page.
I'm very weak in diagram reading, so should probably step off here. That said, I notice at the very top of the first page of diagrams, there's a Relay with notation "Connects to Tail/Clearance Lamp Relay."
I can tell from the image, that it's a common "Bosch" relay. Terminal 30 should provide power that's going to light those bulbs when the relay pulls in. Terminal 87 will carry the power to those lamps when the relay pulls in. Pulling in... Terminals 85 and 86 are Power and Ground to the internal Coil that pulls the Relay in. When one has power and the other has ground, the power available from 30 will be connected to 87 and the lights come on. The relay can be wired so the coil is always Hot (power applied to it) and your switch grounds the other terminal. I doubt it's set up that way. I sooner believe the switch powers a relay terminal to pull it in, and the other terminal is permanently grounded.
So you need TWO power sources at the Relay, with one of them controlled by your running light switch. The other (30) will probably be hot all the time. I'm sure there's a fuse feeding 30, whether "chassis" or "trailer." I took a quick look at the Chassis wiring diagram and didn't see something called "Trailer" at the rear of the chassis, only "4 and 8-pin to wiring assembly tail lamps" so maybe that means your running and clearance lights are off the chassis.
