Bad voltage regulator in the alternator.

Look at the 2 terminal plastic connector on the back (non drive end) of the alternator. Probe the red wire terminal with a multimeter, putting the other multimeter terminal at the positive terminal of the over charging battery. Measure the voltage. You are looking for faults in this wiring circuit, could be dirty connection or fusible link.
