It is probably normal for the fans on the converter to not run, they are thermally controlled. turn on a lot of 12 volt lights and etc. and you should hear them come on.

Then there is the basic idea that the Converter is only active when plugged into shore power thus not an issue when not plugged in. ;-)

Good point
However on my coach the converter is activewhen plugged into shore power... AND whenever my generator is running .

.....and on 99.9% of all coaches. nothermark was simply trying ti differentiate between no applied 120vac and being hooked to a power source.

Understood...(but I have no way of knowing whether either nothermark or keysjunk, the OP, knows that).
Sorry.

FWIW, I should have said when there is 120 VAC present. The original issue is there is no 12 VDC when there is no 120 VAC but the batteries are good. I was pointing out that the converter would not be a likely problem under those conditions.
It really sounds like the 12 VDC is not getting from the battery to either ground or the +12 VDC distribution panel. Since he said he can hear the relay clunk it sounds like time to get out a meter and start checking for where the power is lost. The relay actuating would seem to indicate the ground is not open as it passes enough current to run the relay. That would have me looking for a fuse or connection or faulty relay. They can clunk but not make connection.

I pulled the 12v power switch and it does not have any 12v power to this switch. so this being the finding this switch can not be connecting 12v power to anywhere. I've traced the wires from this switch and they go to under the refreg. There is so many coils of wires in this area you can not trace where they go. I do not see them going to the converter unit. Again thanks to you all for your ideas.

If you are talking about the actuator switch for the disconnect relay you are wasting your time if the relay actuates. You said you are hearing the clunk. If you do hear it you should be looking at the voltage on the heavy wire path from the battery to the relay to the DC distribution panel bus connection. There should be a fuse or breaker in the path somewhere. Figure out where the power stops and then we can help you fix that. Measure the voltage from the heavy wire to ground and toggle the relay. Between the relay and battery nominal 12 VDC should be there and stay the same level. After the relay the voltage should be there and change to the converter voltage assuming it is plugged in or just be there if not plugged in. Post some numbers.

The disconnect solenoid being discussed back in reply 5,6 & 7 is the one on the RIGHT (not the left) in the diagram linked to. There are fuses mounted on that solenoid that should be checked.
