Most likely the bridge rectifer, that is what usually goes bad first.

You know what Alt it is or what car you have? It isn't to hard if you are at all mechanically inclined.

f-ing 09ers would have this **** happen to them. kidding. How many amps is your alt, and how many watts are you running, cause im thinking a possibility that your alternator has now just gone bad.

What made you check the alternator in the first place, did you find that your battery was running low on juice? Could be that the dmm is wrong.

Personally I would get in touch with mechman. I am sure you paid good money for it. And you F***ing around with it will void any warranty you have.

Make sure the terminal on the back of the alt is tight and terminals tight on the battery as well. Hopefully its just terminals, but sounds like the alt is completely shot and now the car is just running off the battery.

i touched the DMM to the tips of the terrminals so i cant be that. and yes the car is pretty much just running off the battery
