I just received a replacement motor assembly for my Abra Ca Dabra. The original had a chewed up fiber gear. The replacement installed easily and the switches were all cleaned and checked for proper gap. I used a small amount of Super Lube on the edge of the drum where the dogs contact it.

Fast forward, after playing the machine for a day or so, now the scoring will just stop in the middle of a game and the ball remains in the out hole. Power continues to flow to the sling shots, pop bumpers, drop targets, and flippers.

Should I look for a score motor fault?

I played over a dozen games yesterday on it, and it now plays perfectly. FM...
