I just loved the mad electric dissertation. I think I finally understand the three wire alternator.

To Frisco: Yes, your jumper wire works fine, but you loose the advantage of running the sense wire to the central junction. If your wiring harness has no voltage drop, then it's not an issue.

I do like the idea of having the 'charging cushion' for recharging a weak battery. Say, on the ride home after you left your lights on. Done that more than once.

I gotta rethink the wiring on my 64C10. ( one wire ) I have a heavy guage wire from the alternator to the battery, plus the stock charge wire. I did that primarily because my electric fuel pump, HEI, and fan all go direct from the battery.
