But did you do as Chris Bryant suggested 10 days ago? His point was that the alternator charges both the Chassis and House Batteries. If the House Battery somehow is presenting an excess load, maybe a short, an auto-reset circuit breaker could be heating up and tripping, then cooling into reset and applying that load again. Again AND again, actually.
Have you/Can you find where the House ties into the Chassis charging system and temporarily disconnect it? If the problem is in the House Battery itself, disconnecting the Battery could release the load and maybe the alternator overload and release will go away. If the problem is in the wiring other than the Battery it might not. But try it if you haven't.
IF YOU DO, don't let the cabling just hang. INSULATE the bare battery cable terminals.
