I never thought about the break away switch? I dont know much about it other than it is one on there and it looks like the one that came on it? How do you check the break away switch or disable it?

Could the break away switch cause the problem I mentioned above or is it isolated from the 7-pin stuff?

All the greakaway switch does is engage the trailer brakes whe it is actuatede. It shouldn't have any effect on the lights unless it is miswired, and you would notice the trailer brakes locking up when you use the turn signals...

I think that one of the problems you are seeing is that when you measure continuity on lines to lights you are reading the ground through the filament of the bulb. I would remove the bulbs from the sockets and measure again.

The more I think about your problem, the more it sounds like it could be caused by bad grounding. Verify that the ground connection from the connector on the trailer is clean with no corrosion. Also check where the ground for the bulbs attach to the ground. Good Luck and hang it there!

Thanks everyone! I am going to work on it some more today.

OK, here is an update. I found 1 bulb in the right rear turn signal fixture shorting out and another one not making contact. The one making the short had a terminal wire hitting the side of the socket due to a worn out insulator. I also found that the Hoppy adapter on the truck is still giving trouble, its shorting or just plain failing. I can make all the lights on the coach light up and work fine using the flat 4 prong plug on the side of the 7-pin plug.
I think this problem is resolved!
