One more thing I need to be clear on. My drawing above shows the Alt terminal #2 jumper wire, just as everyone and his uncle wires the SI alternator, which is incorrectly.

The purpose of the voltage regulator is to control the Alternator OUTPUT, based on what the Battery needs to maintain the correct charge. The best place for terminal #2 to get that information is directly from the battery. The battery junction block is the place Alt terminal #2 should be connected to.

One more thing. If you are going to use an HEI distributor, DO NOT use that yellow wire on the "R" terminal of the starter solenoid. Leave that terminal unused.
