Not good to pull cable off batteries to test alternators an yes could be alternator or u may not have power to the alt.meaning the wire on top of alt or may havy bad plug wire boyh easy to check

The car is having power drained somewhere. Check for an electrical short or some kind of "on" power source. Good Luck!!-----------------------------------------------------------------------------------

their is a shout in one of the wires running from the alternater start at the alternater and work your way back from their. the alternater will test good as it shuts down for safty so the car will not just keep produceing electricity and start burnning wires.

Just cause its a new alternator does mean it should work. I would check the charge when running cause it could just be a bad alternator.

When you say the fuse is good, do you mean the fusible link. 140 Amp? See diagram below. The link is the only thing that can prevent the battery from charging. Check the voltage at the battery with the engine running. It should be at least 14 volts if the alternator and circuit are good.

If the vehicle stalls when you pull the battery cable loose from the battery the alternator can not be good because the car would stay running. You have an issue with the charging system, Possible voltage regulator which is in the alternator. Have the alternator taken of the van and tested a the parts house.

Try re-doing all connections, check your alternator at a national parts store chain, and if the alternator passes, replace batt.

Drive the car to the auto parts store and have them test the battery and alternator for proper charge.  You probably just bought a dud, even though they are new.  Doesn't happen much but does happen.

start the car,, leave the car on and disconect the battery if the car still on the alt is good but if the car turn off Replace the alt

Mazda Mpv 2000 I also have the same problem, the alternater is testing good- 14.12Amp, so what is the problem the battery light will not go off.
