Hey I’m new here and have had my 06 Vulcan 900 for a few months now. I noticed about a month ago while riding at night my headlight appeared to dim out slightly then get bright again. When it first started I thought my eyes were playing tricks on me. Fast forward you tonight, it became very noticeable so I bought a new bulb think the low beam side was getting ready to fail. I put a new bulb in and went for a ride and 5 min in it blew both sides of the bulb. I got the bike home and put a meter on the battery and at idle (slow) I’m getting about 12.98V but under acceleration the meter climbed to 18V!!!! I shut the bike off so I don’t blow anything else. Thoughts? Regulator? Stator? Short? Any help is appreciated.
