Alternator Failed - 2006 F350

[Black06]

kinda sounds like MINE...friend of mine says that w/ TODAYS systems
the alternator / regulator will charge as needed...im not sure i believe
that.

i used my cyberdyne in bartmans truck (7.3L) and saw what i would
TRADITIONALLY expect...that is to say i saw a charge voltage (truck
running) of 14.3 and a battery voltage above 13v.

Just ran a test:

Conditions: Air conditioning on/ radio on/ headlights on = 13.0 V whether idling or 2,000 rpm.

Alternator is 3 days old. Would this be considered normal ?

Thanks

for idling that doesnt sound bad...
