Should your 2002 ford windstar keep running if you disconnect the negative battery cable?

Probably not. That is a very dangerous test. You create a voltage spike when unhooking the cable with the engine running. This spike could damage any of the computers on the car. The proper way to check an alternator is by it's output voltage when under load.

How do you reboot a car computer?
Disconnect the negative terminal of the battery Leave it disconnected for an hour. (The amount of time it takes to replace the battery). Reconnect the negative terminal of the battery. This works because a transient (voltage spike, noise) is generated when the terminal is reconnected. This is not necessary when the battery is replaced because the negative terminal is normally the last connected. However, when a car's battery dies in storage for example and is recharged with disconnecting the battery, the car might not start because the computer is not running.
