Baffling Charging System Question

Wow, thats good stuff there guys. Daliant, I do have 12V at the second added field wire, and I'm assuming resistence at the other, but no voltage, so I'm assuming that the regulator is functioning properly and the ground to the firewall is good and clean.

That leads me to inspect the alternator according to 67Dart273's excellent post. This alternator is an "off the shelf" model, meaning I picked it up off the shelf at the shop and slapped it on when my good one went bad on me. I can totally expect foul play with this alternator, and will inspect it and check for continuity, and a few others I have for the correct dual isolated field model in which to use.

Thanks guys for your informative posts!!! Geof
