Charging the coach battery
I have a 2004 Four Winds Fun Mover Class "C" built on a Ford E-450 cutaway van chassis. Recently I have noticed that it appears the coach battery is not charging when the chassis engine is running....

I wouldn't tolerate a mickey-mouse setup like that for ten seconds. An automatic bi-directional charge relay is autonomous, and very durable. Check into the Sure Power bi-directional model.
The solenoid closes with the depression of the "Boost or AuxStart switch" just like the Sure Power.
The circuit board that the OP mentioned seems to be gating voltage to close the solenoid only when charging level voltage from the alternator is present. Just like the Sure Power.
There does appear to be some cable of contact resistance in the OP's setup somewhere, or his alternator is weak, but I see nothing wrong with the "mickey-mouse setup".
It doesn't seem to offer Bi-Directional activation, but that's pretty common in a Class-C.
Monaco, Winnebago and others used this setup for over 40 years before adding Bi-Directional charging in some of their largest rigs.
