Back in October, I finished the restoration work on Big Hit.  It looks good and plays well, but I’ve found a few minor issues cropping up in it.  The other night, I had the time to do some research…

The first item I looked in to was the left-side special light.  I have replaced it twice in two months.  I realize light bulbs can go bad at any time, but this seemed a little too frequent for my taste.  I inspected unded the playfield for any loose wires to see if anything was making any accidental contact, but I found nothing.  The only thing I did find was the wiring for the flipper coil wrapped around the light fixture wire.  I realigned all of the wiring, to make sure it was not touching.  I wasn’t sure if the higher voltage in the flipper wires were somehow increasing the voltage or amperage to the wire for the bulb.  Since these are wires covered with fabric insulation, not rubber, I’m assuming it is possible for something like this to happen.  We’ll see…

The next issue was the ball shooter.  With the wiring diagram in hand, I traced the problem to a switch on the score motor which was not making good contact.  I cleaned and adjusted the switch and that problem is now resolved.

The last two items which popped up were the upper right and lower left flippers not returning to home properly.  This problem cropped up as the temperatures outside dropped.  Now my game room is heated, but it is cooler than the rest of the house.  I know that at work, the pinsetters require minor adjustments as we go from warmer months to cold and back.  I’ll need to investigate this further…
