Why are you disconnecting the battery with the engine running? Never mind, you've probably already figured this out by now, but there's a good chance your alternator is fried and your spark plugs are running on battery power. Get your alternator checked out. New ones aren't that expensive (approx. $50) and can be changed by anyone handy with tools.

Why do people keep telling others to check their alternators for cars by removing the cables as it is running when they know it will cause the voltage regulator to be ruined?
This will not work on many OBD (compterized) cars. The engine will die shortly after disconnecting the battery cable. The computer must be power by the battery.
Which battery lead do you disconnect to check your alternator?
You don't. Disconnecting a battery cable to "check" the alternator is not a good idea. The removal of a cable with the engine running cuases a voltage spike that can damage the computer system on the car. The proper way to check the alternator is with a volt meter.
