Hi there,
You can see my other post with battery troubles. They sold me bad brand new battery. It didn't work and I didn't want to believe that new battery is bad so I measured what's coming from alternator.
At about 900 RPM idle motorcycle is sucking about 1.5A out of the battery. Voltage is about 11.8V-12.0V. I have dual headlight mod so that may be a culprit.
Raising RPM to about 1200 -1500 RPM gets voltage up to 13.5V and some current charging a battery. 4000 - 5000 RPM or more gets maximum charging current at about 3.5A. Didn't see more than that.
That is all. May help someone when troubleshooting ...
