I have a 2008 Streetglide that I recently replaced the battery. I've replaced the battery multiple times but this time I'm noticing that my voltage meter isn't acting correctly. When I turn on the bike the voltage meter shows 0 but when I start the bike it creeps up to 16-18v, then it bounces around sometimes going back to 0. I went on a 2 hour ride yesterday with this happening and every time I started the bike the voltage showed 0 then creeped back up. I've checked the battery connections and made sure everything is correctly connected. I'm confused on where I should start troubleshooting this issue so has anyone else had the same problem?
On the other hand going passed 15 volts is also bad and possibly signifies a bad connection to the battery. The battery is itself an excellent regulator to hold the voltage steady.
Congratulations on your first post to HDF,
to the Forum.
1. Make sure your battery is fully charged.
2. Get your battery load tested at a local parts store to ensure it is a good battery.
3. Go here for troubleshooting guidance instead of guessing:
If you are using the voltage meter in the fairing to get these readings, get a real voltmeter to determine if it is accurate before trying to diagnose.
But an initial impression would be a faulty voltage regulator.
You'll need a good volt meter to diagnose correctly.

100%. Just replaced the voltage regulator in little brother's '19 ultra -- it was acting similarly.
