That's easy to check: When you turn the key to ON, does the Gen light illuminate? Then when you get it started, does the Gen light go out? If so, the light works and is feeding current back to the alternator. Then check the running voltage. That should be around 14V.

If the voltage to the CDI is around 6.7, instead of 12.6, then you probably have a poor connection in the wiring harness. Pull apart the connectors and clean the pins and spring the pins so that they make better contact.
Thanks so much for your reply, Pete. I have a dual battery set up, as original using Odyssey Batteries. They are only a year old and for some reason don't seem to be charging. Or there is a parasitic draw on the battery, as they lose charge over a day or two. I am really struggling to identify what is going on, very mysterious. 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
