Not sure what a BCC is, but I just assumed that since the RV has an AUX start switch in the cab that it should also have a BIRD, but I'm just going off of what I read online...

Your Four Winds is over 2 years old so it either has a BIRD or Battery Control Center (BCC) which perform the same function. If your system worked and now does not, then it was installed correctly. Both BIRDs and Trombettas have been reported as bad in this forum, so it could be either, if the fuses and wiring are OK. Since it seems to work from the alternator to the Coach batteries this lessens but didn’t not eliminate the chance that it is the Trombetta. I would look at the fuses, the wiring and check the BIRD first. Good luck. These electrical problems can be very frustrating. It took me two weeks to figure out that Thor had miswired the BIRD at the factory.
