Hopefully someone has already had this problem. I hooked my headlight back up the other day after not having it on for a few weeks and it wouldn't come on. I pulled the bulb out and used a 9 volt batt. and it worked fine. I checked the switch with a volt meter and it is working properly. I checked all of the connections on the wiring harness, no problem there. All the grounds look good. I tested the voltage at the bulb connector and I got a reading of less than a volt, so I pulled the flywheel cover off and it seems as if a lot of condensation has been forming inside so I cleaned it out with electrical cleaner to no avail. I know that the flywheel had a lot of corrosion on it so I'm figuring that the stator probablly isn't looking all that great either. I'm figuring that I have either a bad stator - corroded one, or a bad voltage regulator. Any advice would be greatly appreciated. Thank you and God Bless.
