65 Dart Alternator Not Charging

You need to add one wire for the 70/ and later system. Hook the new "flat" VR up like the old one, make sure it's grounded.

Hook the green to either of the two fields on the isolated field alternator, then the remaining field, you run a new wire up and around and tap it in to the blue, which is switched 12V run voltage from the key switch
That would be if I kept the newer alternator correct?

Earlier in the thread it was mentioned that I could get a solid state replacement for the earlier alternator. I may be mistaken, are there solid state versions of the older style VR? If so I misunderstood, I could look for one of those solid state older style VR.

Edit: I found a solid state older style voltage regulator here: 100% New 12V Alternator Voltage Regulator FOR Chrysler Dodge Plymouth | eBay

I wasn't able to find a solid state one on summit or other usual sites. This one isn't too much, so I may grab it and see if it'll work.
