Battery checked good, 850 amps and good load recovery. The alt checked good, 13.8 volts, it could have been a little higher but well within the good range.
I installed the battery and checked the amp draw. This is interesting, it had a 3.5 amp draw when I first installed the battery which dropped to about .2 amps after a few minutes. I am going to put the alt back on and start looking for the culprit. Seems like it may be an intermittent problem.
I will post more as soon as I finish tests.
