1) why are you taking the battery cable off the car while its running?
Never do this to a computer controlled car.... I don't even care who says what its supposed to do... This is bad for any Car with a computer... So please don't let anyone do that to your car again..
Ok now, Is there any amount of voltage supplied to the connector at the alternator? Also is it a 1,2 or 3 wire connector?
The PCM on these cars supplies the alternator with a Positive voltage to produce power... Generally, you get a couple of seconds from the time you start the car to the time you see the voltage gage go to 14 volts...
If there is no power being supplied to the alternator from the wire the Alt will not produce any power at all...
