The alternator light is green and does glow upon start up. With 200-300 rpms, the light goes out. I am going to go through all connections to ensure good contact. Good news is, I have a beautifully restored CDI box from Bob Ashlock arriving Friday and looking forward to having that piece of mind. Cheers
Hopefully, you are aware that this indicates the alternator has entered the charging mode, right?
At this point, your voltmeter at the battery should indicate an increase in voltage, e.g. 1-2 volts.

By the way, the Bosch 3-pin CDI unit rarely if ever fails, not like the 6-pin ones. Why waste your money?
The 3-pin CDIs typically fail when the battery is jumped in correctly, or a tech shorts the ignition coil to ground while troubleshooting.
