Thanks to all for the help. I finally sorted out the alternator. I removed it for the 3rd time and did my own bench test. It worked! Turns out it has to have battery voltage on the alternator + terminal as well as the ignition post. The battery isolator diode was preventing that. A simple jumper and it puts out 14.1 volts. Interesting that once it starts putting out voltage you can remove the jumper and it continues to charge. If you turn it off it needs the jumper to start again. Apparently once excited it doesn't need the jumper.
