Fred, you are awesome! Going to that much work to test a theory.

The reason that the blocking diode is in the circuit is that if the 8 gauge alternator output wire were to fall off, the alternator would attempt to charge the battery and operate all the electrical components in the car through the W/B wire and the warning light coil. The diode prevents this.

The 11.5 Volts is not normal at all. The L and S terminals should both be reading somewhere near the alternator output voltage.
