I'm working on a Williams Fan-Tas-Tic and have got everything working except for the 50 pt relay circuit.
When engaged, it only counts 40 points, so I guess one of the pulses from the score motor impulse cam is being cut off at some place. Other circuits fed from the same impulse cam switch are working fine.
Cam 5 switch A is supposed to cut power to the 50 pt hold-in relay after 5 pulses. Is it possible for this cam to go out of position so that it cuts power too early?
