Coach Battery power off and on?
We have a 2004 Allegro Bay 34XB on W22 Chassis. The coach battery goes dead and come back on now and then. I have had the batteries checked and the converter is ok. Just drove it to get gas and whe...

Yes, any of the above could be causing you to loose power from the house battery to the coach.
First thing is to check that connections at the batteries are clean and tight.
Visually check for other connections-- if you have your coach's wiring diagram follow the positive wire from battery to salesman switch. So, you likely have a large breaker/fuse and then either a mechanical salesman switch or a solenoid-based one. Again check connections.
If all that is good, and you have a solenoid-based salesman switch, next time this happens pull out your voltmeter:
One large lug will have 12 VDC from the battery-- confirm. If not, problem is between there and the battery.
With the salesman switch on, the other large lug should have the same voltage-- confirm. If not either the solenoid is bad or the it is not getting the "signal" from the salesman switch. Some solenoids have one small terminal, some two. If one, it will be the positive (should read 12+VDC) from the salesman switch and the body of the solenoid provides the ground. If two, the second will be ground.
SO, if the small positive terminal has 12+ VDC, but both large lugs do not have the same voltage as each other and the battery, the solenoid is bad. If no power to the small positive terminal, find out why.
