Double check the output of the alternator at the battery, with the lights on (full throttle) and with them off. If you aren't getting a good reading (13.6-14.5) then check the output at the rectifier. If output at the rectifier is good, then it is most likely the switch.... but could be a multitude of other places. Report back your findings and we can move from there. It is still most likely (most common point of failure) a connection issue either at the switch, or inside it.
Just curious..... does the switch get hot to the touch?
