old shade tree mechanic trick is to take a screwdriver and place it at the back of the alt. right in the center. if the alt. is charging there will be a magnetic force "suck" the screwdriver to the alt. i've done this on good alternators but have never had a bad alt. to try it with so i can't be absolutely sure that it is a valid in car test. try it and let us know if it's true or not.
ok- got the charging working again by removing the ground wire that came off of the v regulator. turns out the ground terminal to the reg shared the post with the brown wire going to dash and gen light.
ok- battery now sees 14.5 volts at ~2500 rpm. 13.8 or so at idle. seems like it's ok.
the old reg didn't have the separate ground strap- used the reg body instead- i surmise.
