Whether that's your charging problem will require some trouble shooting, but it could be.

Id look at doing the 3G upgrade and getting rid of that voltage regulator. Do a forum search and youll find the thread. You can do it cheep by going to the junk yard.

1981: Ford replaced the points style regulator (D4TZ-10316-A [replaced C3SZ-10316-A]) with a solid state regulator (1990: FOPZ-10316-A replaced 1981's E1PZ-10316-A).
