Upon receiving my Mata Hari, I noticed the previous owner had cut out the knocker. I am hooking up a new knocker, and would like to verify the correct wiring.

There is a black/yellow wire - schematics have it labeled "knocker"

There is a white/yellow wire - schematics have it labeled "solenoid bus"

Correct me if I am wrong...

The black/yellow (knocker) wire gets hooked to the anode side of the diode.

The white/yellow (solenoid bus) wire gets hooked to the cathode side of the diode.
 
Answer:
The wire that goes from the power supply board (+43 VDC) to the knocker goes to the cathode (banded) side of the diode.

The wire that goes from the driver board to the knocker goes to the anode (un-banded) side of the diode.
