Battery light on

My 2000 ZX3 had the Battery light on for 2 days (my son failed to tell me about it) and had to be jump started. Got the car home and charged the battery overnight. Checked voltage in the morning. 12.5 battery volts, and 13.6 with engine running. This I thought was on the low side of acceptable, so we threw a battery at it. Batt light still on. I started to remove the alternator and found the blue wire (the center one) on the 3 wire connector broke. Reinstalled the alternator, and replaced the connector, and it works like new. 14.8 volts.
