My new-to-me bike was not charging the battery.

I googled on this website www.electrosport.com a nice flow chart that helps us, the mentally challenged, to diagnose the origin of the issue.

After half hour of testing I found out that an hidden connector between the stator and the RR was the culprit. A quick cleaning and voila the RR is charging the battery.

Here the link to the document: fault-finding-diagram.pdf

It is mainly directed towards japanese bikes (wire color code) but the diagnostic method should applied to all bikes.

Electrosport sells different electric/electronic products to repair or improve your bike. I'm not affiliate in any way with them.
