0 120 489 882 993 part no I believe
K1 14W 65A 21 electrical description
070 903 023 E I do not know.
I am not installing in an auto so colors etc are not applicabe. It is being used on a demo unit ie make power with bicycle for use in school training.
What I need to know is how to hook it up. Which terminal does what? Not even sure if it used external regulator. Wiring diagram and photo would be great.
Thanks for help

They give instructions on how to identify and wire the different alternators. | | | | | Joined: Nov 2005 Posts: 6,061 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,061 | Hy leitmotif, I think the original application for that alternator was 1980 - 83 Volkswagon Vanagon, hope that helps. | | | | | Joined: May 2010 Posts: 20 New Guy | | New Guy Joined: May 2010 Posts: 20 | That is an externaly regulated aircooled vanagon alternator. Here is a wiring diagram but it will not help much as the terminals use plugs for the reg. B+ is output D- is the charge light There should be 2 or 3 more terminals that accept a plug to the regulator.

There are only two terminals to hook up to, as Toolbox said B+ is output connected to battery positive, and D or D+ is for the no charge light. Of course for there to be a complete circuit you will have to run a ground wire from the alternator housing to the battery negative terminal. I have never seen an externally regulated alternator with only two terminal connections, hope that helps. | | |
