From our phone conversation, it appeared you had check or replaced everything in the charging system. Verified wiring connections, grounds, battery condition, alternator output voltage, etc. You also stated that you are not having any starting problems...But the charging light persisted...
I may not as familar with your manufacturers wiring design, but they all work similar. Sometimes waiting for something to outright fail is the easiest thing to do...at worst you'll need a jump to get the car home...and the problem will then be evident. Did you have the battery load tested off the car? The black tape comment I made was an attempt at humor...(you could also remove the bulb from the indicator light for a cleaner look on the dashboard)
