Skip white distributor wiring

12--13 is not charging. If the battery is near up, running the engine RPM up a little should show near 14V

Your regulator and alternator field hooks into the original ballast wiring. If you cut any of that OR the wiring was in poor shape, it could have broken connection. It all junctions at the ballast connector(s)

The regulator connector may be nearby and you may have moved/ jogged it, not making connection. Remove the regulator connector and push it in/ out several times to scrub the terminals.
