Ok, my sister has a 90 dodge caravan. Lately it has been dying, especially at idle, but even sometimes in the middle of driving.
I just fired it up and it was idling fine. I put a voltmeter to the alternator and battery and got:
Alt: 20v DC, ~43v AC
Batt: 19.4v DC
Both of these DC volts seem a little high, and I'm also wondering what the AC voltage could mean.
I cranked the vent fan all the way on, turned on the headlights, turned on the radio, then rev'd the engine a few times and then let it fall back to idle, at which point it died. During the reving I could hear what sounded like a relay kicking on/off at the right side of the engine bay (where most of the electrical is).
Any ideas? Bad alternator?
