Ahh... this might be because you didn't connect the sense wire.

Most of these "one wire" alts are really three-wire.

THe big stud goes to the battery obviously.

On the two-pin connector on the side, is idiot light and sense.

SENSE also goes to the battery; not to the big stud. It seems
needless, but running a separate wire from SENSE to the battery
lets the alternator measure the ACTUAL battery voltage, and
compensates for voltage drop in the wire to the big stud.

The otherone just drives the idiot light.
