Hand of Fate lamps are wired together and are actually part of the GI circuit and not part of the lamp matrix. They connect to the white-violet and violet pair of J121 on the driver board. Like all GI, they are controlled by a triac on the driver board... which is controlled by the CPU. The test for these lamps is in the GI menu "Return Lane/Coin". The wiring is a direct shot from the driver board to the lamp on the left lane...the lamp on the right lane is part of the lamp board... you'll see there is a .156 3 position connector on that board right next to the lamp... that feeds that one bulb (white-violet, violet pair) and that connector is wired to the bulb on the left lane.
Can you control any of your GI?
