I thought I knew how to use a volt meter

On my 01 I had issues. I pulled the connector from the stator to the regulator off and had zero VAC, if I remember correctly the service manual says it should be about 21VAC at idle, and increase with RPM. The stator makes AC voltage and the regulator converts it to DC voltage to charge the battery. If your getting 0 VAC off the stator replace the stator.

Advanced
That`s because the alternator has a built in circuit that changes A/C volts to D/C volts as well as dropping the voltage to a usable level to charge your battery. You can`t read the generated A/C voltage, only the output D/C voltage. You can read an A/C voltage drop to ground from the positive battery terminal, which will read very low (something like .3 volts) to indicate if your alternator is functioning properly. But this has nothing to do directly with the final D/C voltage output. In other words, there is nothing wrong with your meter.
for the the heck of it I changed my meter to AC and put the leads on my battery terminals. It showed 30.1. So I am pulling AC to my Battery? Possible regulator failure ??

yep, went from generator to alternator. the early ones were dual wound units with a special regulator. there was a main output winding and a field forcing winding. this worked similar to the old generator which had main output from arm winding but field forced by the shoe and coil arrangement. the newer ones are single phase series wound bobbins. the three phase would be the same but with three series wound coils(alternating). since the form is insulated from ground, all measurements will be between leads, any measurement to form shows shorted coil form.
you can actually re-wind them yourself if you have a hankering to do so, very easy and you can build a better mouse trap since the HD unit is engineered to do the job with less cost and is borderline.
