Replacing a sound board with a chime box
Steps
- Mount the chime box on the lower cabinet side wall beside the knocker, near the power switch.
- Take 25 V coil power from the knocker's banded-diode lug and run it to the banded lug of all three chime coils.
- Move the orange/black/black wire from the sound board connector to the free lug of the 10 point chime.
- Move red/brown/yellow to the 100 point chime and red/green/green to the 1000 point chime.
- Take the sound board out of the game.
