Not even sure how to describe what's going on here, but... Depressing either flipper button adds 500 or 1000 to the score. Sometime when you release the flipper button, it adds another 500 to the score. The inner outer right lane at the bottom (the ball rolls through it back to the flipper), isn't scoring anything, most of the time.

Ok, NEVER MIND. Fixed it (figure I'll leave the post here for if anyone else comes across this problem).

Turned out, the contacts on that inner outer right lane at the bottom were mashed closed. Hitting a flipper actually caused enough vibrations to momentarily open them, and then they'd close again...adding to the score.

Funny how I found it. As I was taking the balls out to raise the playfield I accidentally dropped a ball. Slipped about 2" out of my hand and hit the playfield, and the score increased. Tapping on the playfield, at the bottom only,caused the score to increase. Figured it had to be mis-adjusted contacts at that point, and something near the bottom...and since there were also problems with the lane switch, that's the first place I looked...now if only I could fix my eyes so I could see better
