Quoted from CreepyTom:Just got a Premium Refinery Edition. The Sparky switch seems to be going off without being hit a lot, really affecting gameplay in a big way. Any clue how to fix this maybe how to make it less sensitive. Also is there a way to set the music louder than the callouts and sound fx? Also music doesn't seem to get too loud even with the flipper fidelity speakers in it. Where in settings menu can i go to maybe fix these things? any help would be greatly appreciated, looking forward to the club!!!!
Mine started doing the same thing and the opto sensor was off that is in front of Sparky. I ended up having to bend the metal tab a little that holds the opto sensor. The bad thing about it is, that its hard to see and get to because of the left ramp and other things being in the way. I ended up taking the left ramp off of the game and the plastics around Sparky so i could see what i needed to do better. It actually wasnt that big of a job but after about three failed attempts of trying to get it adjusted I said F it and took the ramp off so i could have some room to work and so that i could see what to do.
I was getting sparky hits just by flipping the flippers and yes it does ruin the gameplay for sure. Maybe someone else can Tell you a better way to fix this problem but thats how i fixed mine. If you look in front of Sparky you will see where the opto sensor shines from one side to the other. There will be a round red circle of light that is supposed to shine into the hole on the opposite side of the opto and mine was way off and barely shining into that hole. I suspect that this may be your problem also. Its also possible that the switch that sits between Sparkys legs may be too close together and registering way to easy. If thats the case you will need to gap that switch open a little more. Check that switch first and then the opto. If the opto is off center though i would say that is your problem. Good luck!
