Believe it or not, ...as I understand it ...and could be wrong, on a lot of the newer alternators, if the battery is not charged it won't be a high enough voltage to excite the alternator to put out a good charge.

When I installed a new alternator from the parts store the instructions said to charge the battery fully before trying to start this thing.

Charge the battery for several hours, then try running the engine again and see if that helps.

Also, verify good, clean, connections. I like to use a wire brush to clean up the area on the block the negative cable attaches to, clean the terminal on the cable, and make sure the bolt is tight. A star washer helps here. Same thing on the battery end. Same thing on positive cable. Clean and tight.

Whoever the "they" is they are full of poo-poo. Max out of the back of the alternator should be around 14.75 volts. 16 volts is too high. The test should have been run holding the alternator within regulation.
