Title: Generator woes - not charging back to battery
Post by: jjwithers on December 18, 2017, 02:02:40 PM
I have a dual bridged rectifier set up that Stuart in England sent over to me with his tried and true wiring diagram. 

With the bike running, i disconnected the 3 generator wires, one at a time, and measured the volts between the 2 wires and the rectifier, and the brown wire connection.
The brown and blue wire had bouncing readings between 10-14v and then occasionally dipping down to .04v
The yellow wire had only between .02-.04volts. 

Seems like my generator is dead due to that yellow wire reading?

Is there a way to jump or bypass that yellow wire somehow so I don't have to tear the whole frigging thing apart... AGAIN.

Or...Does anybody have a known working one to sell with the points 180 degrees apart?

I was able to take a generator that was known to work, but it had the incorrect points plate on it and rusted bearings.
I was able to take my bearings off my rotor, and swap all the parts around by putting my points plate and good (new) bearings on the rotor and stator housing.
I used the SQL 100A 1000V 3 Phase Diode Bridge Rectifier, the bike's battery, and 'bench' tested the generator with a drill.  Success video is here:
