One my system the "What voltage is the battery at" wire and the "Battery charging wire" is one and the same. if yours is seperate then you may have a bad connection between the Alt terminals and/or the battery itself. Maybe the previous owner has a splice in there somewhere?

John, the regulator is internal, and the voltmeter was used on the battery and ground. My voltage gauge also reads exactly the same. I have MSD 6A, MSD coil, and MSD billit distributor. Also, both alternators were painted prior to install. I was careful to mask the post and plug, but I fully painted the alternator and the pully attached. That's all I know about that. Thanks for your help. Wes
