As a few have you had mentioned, since the generator was passing the bench motor test it would likely produce a charge. This turned out to be true.
I had ordered a voltage regulator as it seemed likely that it was acting up. I also decided that I better trace the wires to be sure that everything was wired correctly.
It turned out that the F and GEN wires were backwards on the VR :roll:. I corrected them, then tested with the old VR. The old VR didn't seem to work, but I could get 18V at the A post if I manually grounded the F post to the chassis.
I replaced the VR with the new one, and then tried again. At this point I was getting 15V at the A post, but only 12V at the batteries. I then polarized the generator and then I started seeing 15V at both the generator and batteries at around 1/2 throttle.
Thanks for all the help. I was ready to consider a generator rebuild / replacement, but the wiring fix + new voltage regulator did the trick.

In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
