Common places voltage can 'leak'...

The Vulcan one might fit.

Here's a good site for any info on alternators. They have several good technical articles too if you dig around enough.

Well isnt 92 the year of the lower output alternators? Coupled with my UDPs can't help either. If I get it tested... what kind of amperage should I see @ say 1500-2000 rpm?

No idea. I know how many volts you should see but that's about it

Well.. I just came back from 2 different places, both say my alt is fine. Maybe I just got a bad battery after all.. time will tell, going to put it back in here in a few minuites. I could get 90-100 amps out of it, so it must be ok I suppose. Who knows.. lol
