I bought a used 2014 Bashan sports bike a couple weeks ago, not realizing it was going to turn into a bit of a ‘project’ bike. The problems seem to be related to the charging system.

The battery is good, and holds a charge.
I just replaced the rectifier/regulator, because it had a 4-wire (single phase) unit installed, but the wiring harness has a 5-pin connector.
At this point I need to figure out if I got the wrong part, or if I have a wiring problem, or a stator that’s gone bad.

And that’s just what I know so far.

I don’t suppose there’s anyone in the Cincinnati/Dayton, OH area that might be willing to give a new rider/ novice mechanic a hand?
