Try your question on forums.trailvoy.com, I see several topics on this. If battery and alternator are good (and have been properly load tested) problem may lie in harness connections at back of alternator. It always good maintenance to check all wire connections and grounds. Wire brush them clean and use a liberal amount of dielectric grease on terminal ends.

Could it be fusable link on wire from alternator to batttery?? And does cranking amps matter... New one has less only 600 - old one had like 900?
