Can someone point me in the direction to solve this problem?

Thanks,

If you are at the back of the coach, looking at the engine, open the polished door on the extreme right. Look in there for for a small box something similar to what HoosierDaddy posted. Mine was at the very top right, Black with a yellow label. If you have that, check to see if you have the input signal to it AND the output signal. My coach did pretty much the same thing, and I had to replace that unit. 

I had checked the 7 way plug, and there was a really low voltage output, but not enough to run the LED's on my '21 Wrangler. I then traced the wires back to that box being bad. The input had a strong 12v signal, and the output had that weird sub 4v signal. Both the Left and Right had the same problem. For tracing, the same wire color at the 7 way, is the same wire color to the output of that box.

FYI, I know that on our era coach and beyond, the turn signals to the toad (through the 7-way) are NOT ACTIVE unless I have the parking brake released.

If alone, I test using the turns by using the HAZARDS.

Great point! Use the hazards for testing.
