-Rear firewall just above the radiator has a Ford fuse panel
Here are the problems I'm having.
1. Dash/Windows driver & passenger fans are no longer working. They're controlled by the 3-way switches under the radio. Checked fans and they are not seized up.
2. Map light above driver/passenger not working. Note - I have the drop down bed above the front seats. 2 way switch under the radio. Also controlled locally at the light itself. Neither switch work anymore.
3. Generator start switch works to start the genset, but the switch itself no longer lights up indicated run-state. 3-way switch under radio.
Something tells me all 3x of the above are on the same circuit/fuse, but I checked over 100 fuses and not sure what to do at this point. A bit frustrating.
4th issue, is sometimes after a long drive without the generator running the House batteries have depleted; meaning the alternator may not be charging those batteries. I don't think this model has a BIRD, and I previously had to install a Trik-L-Start to keep the Ford/Chassis battery up while on shore power. Thoughts?
Thanks in advance

All the items you mention are powered by the chassis battery. There is a multi-tap on the positive side of the chassis battery that runs to a 100 amp 12 volt re-settable circuit breaker located on the right frame rail. From that circuit breaker the power goes to the circuit board down by the drivers left foot. This is a Thor MC board that contains all the fuses and relays for the Thor accessories in the front cap. Sounds like that CB is tripped
As for the engine's alternator charging the house batteries, this is done through the BIRD. Usually the Trombetta control module for the BIRD is good but the continuous duty relay goes bad. On my coach my the BIRD is located on the front wall in the rear of the house battery compartment. the
