Help with stator connections  By  natedoggaz (Read 635 times)

I had a 150 once.  If the 3-wire connections are different, and there is not more than one 3-wire connector on your harness, you probably have a different stator than what was original.  

The different connectors is one way of telling a half wave stator from a full wave. They are also soldered at different points at the coils.  If you wire it up to the old connection, it should work, but you might wind up with a "speed sensitive" headlamp.  

There are plenty of YouTube videos on the subject but you might wind up connecting the headlamp to the battery (DC) via a toggle switch.

Good Luck.

I went through it the reverse. I'm thinking your original uses an ungrounded stator and the new one is grounded. this blew all and i mean ALL of my bulbs after running it a few minuntes (again, the reverse of yours as my original was a grounded stator) and attempting figure out why my headlights would go on only at first then dim down to nothing. after a few trouble shooting starts no lights at all. look up diagrams for the two styles and use a meter to check grounds. on one you will get a few ohms between the 2 power windings and the ground wire on the connector to the stator, the other style will read open (no continuity) to ground. also be sure to replace the the r/r with the one that came with your new engine to ensure they match, something i did not do because they looked the same but the grounding circuit for the ungrounded stator is in the r/r and that was ultimately what blew my bulbs.
