Jeff, you may already know this: The Gen light must be an incandescent bulb, NOT an LED. It initiates the alternator field by sending current back through the bulb to the alternator. Too little resistance would not be a problem, but rather too much would be a problem.

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.
