Not to extend your pain bill5h, but perhaps looking at one specific failed item and fixing that one item will help resolve the other items (assuming some common failure issue – like an open +12v or a ground or connector even)? Looking back on your original post you said the emergency start ( or aux start) does not work. So I assume that means no aux relay operation clunk noise when you operate the aux start switch. Based on the 2014 diagram I posted previously can you tell if your coach uses the Bird battery control system to control the emergency (aux) start solenoid? If yes, can you confirm the 12v and ground and aux switch connections on that one system and determine where the circuit is failing. I suggest that system since the parts are large and usually accessible for testing etc. Basic Bird schematic is attached. The coach battery 12v should pass through the aux start switch at the driver’s seat and operate the aux relay through the 5 amp fuse to ground. If the aux switch wiring is not closing to allow 12v to get to the aux relay operate terminals then it might be a bad dash/firewall connector.
