But I did find this part, which I'm assuming is the emergency start relay, which also doesn't work. Big starter solenoid/relay, coach battery voltage on one terminal, truck battery voltage on the other. All it does is buzzzzz when you press the emergency start switch.
Anybody have any idea where the isolater may be located? And is it an actual "relay" system as opposed to a dual diode solid state type?
Like I said, I tried tracing the power cable out, but it goes straight back to the coach battery compartment to this device, and does a bit of looping, and after that there's no telling. Very hard to follow where anything goes.
Any help on this would be much appreciated, but actually we can live without it as long as everything is working.

That emergency start solenoid is also the solenoid that controls the charging of the coach batteries while the engine is running. If it's bad you found your problem.
When replacing it don't replace it with a starter solenoid. You need one like a starter solenoid but it must be one that is made to be continuously on. They call it a 'continuous duty cycle' solenoid.
If you need help finding that I can provide a link to it.
