2004 fatboy. Getting an intermittent battery/check engine light with a no charge. May ride it for 2 weeks with no problems and then it may happen daily. What is the most common problem? Regulator or ????
Simple charge system diagnostics before throwing parts at the bike. Check all connections and obvious stuff.
Check the stator for shorts or open circuit and AC output with a multimeter. If the stator tests good then it's most likely the regulator.
Thanks Schmidty. All connections are clean and tight. Just hard to test an intermittent bad part. I have a regulator on the way. Cheaper and easier than the alternative. Hoping it will act up so i can test while having a problem.
