John...I'm not sure if my response has anything like yours, but then again it might. On my recent trip prior to Pomona FMCA I was told by the person following me that I didn't have any stop lights activating on my coach or toad. After investigating I found that if I isolated the brake and tail lights they turned on OK. Every thing was OK from the circuit breakers back but activating the braking system using the foot brake, the lights didn't work. Eventually, after doing a lot of isolating and continuity checking the hazard flash switch was the culprit. So now I am in the process of ordering a new flasher/turning signal
switch. I hope it will be the cure.
