Hello Everyone,
I'm having an issue with my 2000 Fatboy killing batteries. I read the previous articles posted here about testing the stator and the voltage regulator and to the best of my abilities checked them over. I followed the procedures in the service manual and which was pretty much the same information that I found here.
I pulled the Voltage regulator off unplugged the harness to the stator and checked the voltage output of the stator while revving the bike, the output was what the service manual said it should be. I then took my test light and checked the pins on the voltage regulator and the test light didn't so much as flicker, which supposedly indicates the regulator is okay.
Put a new battery in the bike and rode it all day numerous stops on the ride and cranked like a champ every time. I get home put on the battery tender and the thing doen't turn green showing a full charge for over 14 hours.
In the past the charger would go green within a couple hours at most. Now I'm thinking there is no charge going to the battery while riding.
Question I have is there another component that could be stopping the battery from getting charged? OR do I need to remove the voltage regulator from the bike and take it to a HD dealer and have it tested by them.
I plan on getting into the service manual tonight and going through the wiring diagrams to try an find another possible point of failure.
Any help would be greatly appreciated.
Thank You
