8V92 alternator questions

[Don Bradner]

I've got a few questions after I describe what I'm seeing on my dual-alternator
8V92:

After starting, the voltage is somewhat below 13, and alt2 is running about 50
amps. Alt1 is essentially zero, although there is a slight upward blip when
changing the display from alt2 to both.

Voltage slowly rises, and after quite a distance (100 miles or more) the voltage
is in the 13.5 range. At around that time, the Fault light comes on. Alt2 at
this point is running around 25 amps, and there is no apparent increase in the
both position.

What do other 8V92 dual-alternator owners see for charge rates, 1, 2, and both?
I'm presuming the zero/near zero is telling me I have a bad alternator, but is
the 50 amps from Alt2 also low? If it is, what does that mean?

Does anyone know, on theirs, which alternator is 1 and which is 2? Front top, or
back by the bumper?
