It is not. It uses phase cutting (or just call it PWM). Hence the
absolute need for a large capacitor at the output.

Agree with your points about the battery.
That's why I recommended to test the voltage without the battery
connected. If it reads a correct voltage, we can assume the alternator
is good, we can fairly assume that the regulator works (although it may
fail under load, but is less likely). If the voltage does not read
correct, we can pinpoint our trouble shooting to the alternator and
regulator and don't have to worry about faulty wiring or batteries.
Regardless of the outcome, we can narrow down our search significantly.
