When trouble shooting an electrical issue make sure your test light or meter has known/good ground.
I have found it difficult at times to find a good ground point with these fiberglass bodies.

Yep, have all the drawings. In addition to what Spartan has sent, I also have a factory manual that the shops use... the drawing designations add to the confusion.

I Always use a known good ground when using a test light.

Yea I have taillights heres what I found on mine. In the front there is a relay not a fuse I checked & it was working I then went to the rear found the green wire just to the rear of the air dryer & probed it I had power there. What a relief that was. I then moved farther back tp the tail light wiring bundle & took off the sheathing & gound the problem the cheap crimp connectors had come apart. I then had my work vut out. I took all the wiring out & rewired the whole rear harness using heat shfink vonnectors then heat shrink over that. On to the next project.

Thanks Chevy396, you must have a big block around there somewhere.

Anyway Ron, Chevy396 had some real good suggestions where to check.
Another place you might check is the 7 pin RV electric plug at rear of coach. As you look inside the plug the tail light pin is the one at the 11 o'clock position as you look at it. You should have 12 volts here with the coach running/markers lights on.
If you have 12 volts here you know it's getting to the rear. So like Chevy396 you need to check the connection inside the wiring looms at the rear.

Yea, I'm about where Chev396 is/was. My task is probably tearing into the wiring harness. I think I did check the tow plug and found it to be working properly, but should chk again since that was back in July.

I'm going to guess your light harness looks like mine did. Your just going to have to dig into it.

I am guessing that ours is the same as you say.
