Ok so I just picked up a WaterWorld the other day. When I started it up I noticed that the left upper kicker kept triggering. I went into the edge switch test and the switch 30 for the left ball shooter only registered when switch 31 for the outhole was open. So what I gather from that is that the switch is deactivated when all 4 balls are in the machine. I might be wrong on that. But the real oddity is that if I'm in switch test and I hit my left flipper switch 41, it says I've hit switch 40 for the wire ramp opto. I cleaned the opto and the leaf switch for #30 but still having issues. Why would that opto trip if I hit the left flipper button. No other switches on the play field seem to have any issues. If anyone has ideas I'm welcome to them. Thanks.
