Would it be possible for the voltage regulator to be no good on two brand new alternators?

Probably not. You might do well to take the vehicle to an automotive electrical shop. They can track down problems quickly, no guessing. It IS possible, but VERY UNLIKELY. As answer 1 recommends, you need a qualified auto electrical technician/shop.

What causes a 99 Mazda 626 to ruin alternators?
Probably you are getting inferior alternators. If this model has an external voltage regulator, then possibly it is the voltage regulator instead of the alternator that is causing the problem. As a mechanic, there is nothing in the car that would cause the alternator to be ruined. Alternatively, some people suggest that if your battery is weak, this causes a strain on the alternators, but in 40 years of wrenching I believe that is not the case.
When 2 alternators are connected in parallel what is the resultant terminal voltage of the two alternators?
Since the alternators are in parallel, the resultant voltage should be the same as either alternator - exactly as it would be if two batteries are connected in parallel. Voltage remains the same but current capacity is doubled. I would recommend connecting the alternators through a network that will balance the load between them.
Why would an alternator charge too much?
Alternators have two parts, one is the armature that generates electricity and the other is a voltage regulator. In most cars the typical output for an alternator is 13.2 to 14.4 volts. If their is more or less than this being produced, the voltage regulator may be faulty or the bushes may be worn. another issue that some alternators have is the failure of the bearings inside the alternator leading to noisy running or the bearings inside the freewheeling pulley fitted to more and more modern alternators. these can often be replaced independently.
Does a 1997 Sunfire have a voltage regulator and where?
A 1997 Pontiac Sunfire would have a voltage regulator and it would be found inside the alternator.
Why would a 12 volt car battery give off 22 volts?
it won't. The most you will see from a stationary battery with the engine not running is 12.6 volts. If you are seeing 22 volts with the engine running then the voltage regulator is defective and it will ruin the battery. Most modern alternators have the voltage regulator built into the alternator. Replace the alternator.
Why would your alternator fluctuate on a 2000 gmc sierra my alt crapped out and i changed it twice and both times the voltage fluctuates and the battery light flashes connections and battery good?
voltage regulator, sometimes its in the alternators, advance auto parts doesn't replace them in remanufactored ones.
Why would the alternator over charge in a 1986 ford F250 I have replaced the alt. and the voltage regulator?
defective voltage regulator
What would cause the battery to overcharge?
Defective voltage regulator.
Where is the voltage regulator on a 1995 ford areostar van?
If it's like my 1987, and I imagine it is, the alternator is internally regulated, so you won't find a voltage regulator box like you would on some older vehicles. In short, the voltage regulator is in the alternator.
Does 1969 gto have internal or external voltage regulator?
Original equipment would have had an external voltage regulator. Internal regulators came out in the 1973 model year for GM.
What regulates the voltage to the battery on a 2001 1.6 focus and what would cause it to cook at 17v?
Bad voltage regulator
Transit has too alternators and the battery light stays on which one would it be?
check the output at the hot stud on the back of each alternator, if they are both reading charging voltage (about 14 volts), then unplug the regulator on one alternator and then the other to isolate which one is charging. If you have no or low voltage on the hot stud, you could have a bad cable or ground to the alt.
