Homemade Alternator Test
Hey, I went to a friend of mine and he said that if you want to test your alternator, turn your car on and then take off the negative terminal wire. If the car shut off, your alternator is shot. So I gave it a try and my car just kinda putters like its about to stall, does this mean my alternator is sub-par and about to bite the dust? Thanks

I won't let go
It means that you should put the ground back on. When you disconnect the ground, you lose a good ground path. All the other little grounds aren't going to do squat unless you have that hyper grounding thing going or your contacts are really clean. Just go to radio shack and get a $20 voltmeter.
You could also just grab the contacts too to see if it's working well.

he probably thought that taking off the neg. off from batterie was a homemade test to see if alternator is bad..
which is true.... but not sure why you call it home made... it should be something everybody knows... just like changing tires..

That is a very bad way to test an alternator. Most cars will stall out whether or not the alternator is bad, since as Railgun said, you are disconnecting a main ground.
