Workhorse Tow Connector Fuses

[TC_Z]

We have a Winn 2007 Voyage on a Workhorse chassis. I'm trying to trouble shoot the tow vehicle's left brake light. The MH brake lights work properly and all other tow lights work properly. The bulb is good. I ohmed out the cable, it is good. Best I can tell there's only one fuse, the "LH Tail", to check, it is good. Assume this one fuse operates both the MH and tow together, right? No fuses are labeled MH tail or tow tail. Just "LH tail" and "RH tail". The fuses I find are all good.

My question is:
Are there separate fuses or breakers for the tow cable lights? If yes, where are they located?

I assume the brake lamp is a separate bulb from the turn signal. If that's true, then put a meter on the brake lamp circuit and activate the brakes to ensure power through that wire. If that works, run a separate ground wire to that lamp and re-check. My bet is on a bad ground.....often, it's easier to run a new crossover wire than to trace a broken one, but check the ground first.......Dennis

Did you check the wiring diagram? Here is the link.

I have an o3 winnie and there is a fuse box under the hood (driver's side)..don't know if your RV is wired the same, but..also be sure the ground is hooked to the right terminal on the plug...good luck.
