The regulator is in the engine computer not the alternator.
The computer only resets when the battery is removed. The alternator just charges the battery, so if the battery is left connected when the alternator is replaced, the computer should not reset.
If the battery is sulfated (or otherwise faulty) to such an extent that it calls for a continuous charge, the alternator never gets a chance to switch off. With the resposibilitiy to run continuously the alternator overheats and eventually fails. Never replace a faulty alternator without also checking the battery.
We replaced the alternator on 2 different vehicles. It was around $175 for each.
Inside the alternator, some are easily replaced and some are soldered in place.
