Generally, alternator output voltage is consider OK if it is in the range between 12 1/2 volts to a maximum of 16 volts.
Therefore, although the output is at the maximum, you do not seem to have a problem.
Usually, if the battery has had a lot of drain, then the alternator output will run at the maximum until the battery is fully charged.

1996 Taurus battery charging light came on replaced the alternator and the problem seemed to disappear day later light back on battery not getting charged bad alternator?
you may have a bad battery or a bad voltage regulator
Replaced the battery on your 2000 ford explorer and the battery light is still on could it be your alternator?
Most likely the problem is your alternator....the battery light actually does not monitor battery condition, only the charging system. I'd check the voltage regulator and the fuses first. The fuses are the cheapest fix and the voltage regulator will run about 25% less than an alternator.
Why would your battery light stay on after you have put in a new battery and alternator?
The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.The battery light comes on when the alternator output voltage is too low or too high. You have a wiring or regulator problem.

Obviously check the battery. Anyway, if the alternator, battery, and wires connecting them are good the voltage regulator is next on the list.

The battery light comes on when the alternator is either over or under charging. If the alternator tested good you have a wiring or computer problem. The engine computer is the voltage regulator.

Sometimes an alternator with a weak diode(s)can test out fine, but can still trigger the light. I believe the problem is in your alternator. Good luck.

2 new alternator battery well discharge while engine is running eventualy engine well shut down 0n 1990 GMC Safary?
If you know the alternator is good and wired correctly then take a hard look at the voltage regulator. If the voltage regulator is built into the alternator then look carefully at the battery cables. I would bet your problem is the battery. If it is out of warranty just replace it. A trip to your local Auto Parts store where they can check the entire system, is in order.If you know the alternator is good and wired correctly then take a hard look at the voltage regulator.
