Trying to do alternator conversion cannot seem to find how to bypass this model of regulator
Do I just tie in the green and blue, leave the brown ground alone but then where do I tie the red wire into as all others had 2 in the regulator?

The above pic would be for an internally regulated Alternator.
Sunbug, please post a pic of the alt you are installing. Then we can advise you on the correct way to wire your new alt.

Then bypass that regulator you posted and fallow the diagram above or search for a conversion wiring diagram online. I think J-bugs has one on their website.
