Well, I'm guessing I have a regulator problem. I took the (new) regulator out and soldered a wire onto the sense terminal. I've got a VOM with long leads, so I connected to VOM to the sense wire and ground at the regulator, and when I race the engine I see just a tad over 15 volts *at the regulator*. From the MAD site, it would seem that the regulator should be regulating 14.2v.
Another interesting thing is that the instruction sheet that came with the new regulator went on about it being solid state, and thus eliminating moving parts and the big relays. I took the cover off it, and guess what. Relays and moving parts!! No semiconductors.
