Stop by auto chain store and have them check actual readings at battery. They do it for free. Your gauge may be wrong.

If your gauge reads discharging and its really reading 14.3 volts then the gauge is wrong.

You thru me when you said battery was 12.6 since I assumed you got that reading while car was running and checking voltage at battery.
