Thanks for the replies. I've searched ad nauseum but I'm still unclear, so I'm asking.

So, would it be OK to run the alt. output wire to the B+ side of the starter solenoid? The plan right now is to run the initial alt. output to the Mad terminal block on the firewall, then take another larger wire (8 ga.) and run that back to the B+ side of the Ford solenoid. As I understand it, the B+ side of that solenoid will act in a similar way to the insulated connector on the firewall. At least that's how he (Mad) suggests doing it in his diagrams.

Also, since I bypassed the ammeter, he (Mad Elec. guy) said I might want to run those main feed wires back to the cut off switch to kill the power to the dash (i.e. ign. switch, lights, etc.)

And, do I need to run a second large cable from the B+ post to the cut off switch or can it come from the + side of the solenoid? I'm gonna have to cut and crimp some cables either way,just want to make sure I don't have to re-do it.
