Ok, I start the car, I pull out of Napa, start heading down the road, and I saw that my voltmeter read zero! I kept driving coz there was nowhere to pull over... I look down again, and now it reads 10 volts, and by the time i got home it read 10.5-11 volts... What does this sound like to you guys?

I gotta hit up the neighbors and see if i can find a voltmeter :eek:

How do I test the alternator for proper function?

Always check your battery first, then check:
1) Alternator fan belt still in place.
2) ALL main electrical connections, battery cables, power lead off alternator, junction block, etc. Obviously you want good solid connections and wires that are not all broken up
3) Use your volt/ohm meter to check output at alternator, at regulator if external regulator.

Your problem is going to be in one of those three areas, good luck.

phew! neighbor luckily had a voltmeter. here's the results:

Battery: 12V
Battery / motor on, headlights, rev, 30 secs later: 14V
Alternator: 16V?

I'm thinking it's just a bad/funky voltmeter gauge at this point... Interestingly enough, the gauge is reading o.k. right now.

Sound good?

You might of lost connection with your gauge wiring. Check to see if it's not broken or loose
