Question Atomic 4 Alternator Failure

I have an Atomic 4 Alternator Failure with symptoms below:

-Engine starts and runs with no noticeable issues.
-Engine runs until Battery 1 is dead. (3 to 3-1/2 hours)
-Engine runs with combined 1+2 Battery it will run until both are dead. 7-1/2 hours.

No measurable output from the Alternator (Less than 2 years old)

The alternator was a Single Wire Internal regulated unit.

Is there a fuse in the ignition/exciter circuit?

What would cause this?
