well is ur batt light on when the key is in the run position?if not wiggle the regulator connector and see if it flickers at all. if it does u probably have to replace the regulator connector(like $13). also make sure that the grey wire in that plug and the single grey wire have continuity, then make sure the oragane one is hot all the time, and the green/black wire is hot in run. the regulator plug was my prob. only took me 4 alternator removals to get tested and all good. after 3 mo i finally figured out that it was that connector. hope this helps..
