Re: Alternate Alternator - Saabnet.com Bulletin Board
Not sure if you're still looking, but based on the connector you posted you may need all three of those of those terminals connected:
Ignition - likely goes to a switch 12v ignition source
Lamp - likely a warning lamp or small resistor
Computer - likely a signal from the computer to start, stop, or adjust charging
Most "newer" (like, not ancient Bosch alternators) have these terminals. Some alternators will start charging with enough speed, others require one, some or all terminals to be properly connected to produce correct output. On most alternators I've seen, the computer control terminal is optional (most alternators will have a failsafe mode) but the lamp and ignition terminals may not be.
