I posted this over on engineering/tech.....

need help with theory. 84 cavalier has 78 amp alternator. Voltage light keeps coming on so I'm trying to test with a multimeter. Volts check okay.

But my multimeter has DC amp setting of like 50M (micro amps) 500M 50u etc and a single 10A (I think the max. )

If I connect between alternator grnd and alternator battery out terminal, how many amps should come through? I assume at this point its DC right? THis multimeter won't measure 78 amps.
