I returned home from service to find all the bay lights inoperative. Of course, the service people didn't touch it and have no idea why they don't work.
The Breaker has been reset and is in, I checked for power there as well. The circuit seems rather simple, not a lot of components, just power, breaker, lights.
On my CC the breaker is in the compartment outside, under the drivers side window. There is a light in that compartment that does work and is on the bay lights circuit.
Another thing I noticed is the row of light switches in the gray/black tank dump bay are turned off by pushing the plunger switch that is activated by closing the bay door. Not sure if this is normal or not. Would some fellow CC please check to see if that condition is the same on their bus?

I hate being stumped by these sort of problems, they usually turn out to be something rather simple.
