unplug connector from regulator. the wires from the stator housing, usually 2 or 3 yellow wires should each have a/c voltage output when engine is idling. check them all 2 at a time and you should see min 20-30 volts a/c current and when slightly rev engine voltage should increase, more it revs more voltage should increase. when this a/c voltage gets to regulator it turns to d/c voltage and then stabilizes it to max of 14-15 dc volts. if you don't have strong a/c voltage that's whats wrong. make sure to check each combination of the 2 out of 3 wires while you test. also can check resistance of each yellow wire to ground. 1 at a time. resistance should be infinity or OL. if not that means yellow wire is grounded or shorted internally so in either case you need to replace stator wires.

replace the entire stator, not the wires.
