Looks like the FS relay only triggers while the score reels are resetting. Do you see it moving during reset?

Quoted from BethlehemBill:Did you ever figure out the why the special lights are too bright/burning out? I also have this problem. I put in LEDs and they don't burn out but I would like to correct the problem. IIRC, they had like 20+volts at the sockets.
Good thread, thanks!
Measure the AC voltage across the bulb when it is active - one meter lead on each side of the bulb, if it is not around 6 volts then check out the resistor.
With the power off, un-solder one end of the resistor (to isolate it from the rest of the circuit) and then measure its resistance.
Those sand resistors are supposed to drop the voltage *across* the bulb to about 6 volts. The resistance of an incandescing (hot) 44 bulb is about 25 ohms and the resistors are supposed to be 75 ohms, so the bulb should have one quarter of the 25 volts across it. The resistor should have 19 (ish) volts *across* it when operating in-circuit with a hot 44.
