I picked up an Abra Ca Dabra on Monday and got the match system and half-moon replay counter working with help from great sites like this.

I’ve been playing and have thought, “Man, this thing is tough to beat on score” and this morning I realized why. The 10,000 digit does not rollover all the time. I was just playing with a score of 19,000 and when I looked up as approaching 20,000 the 1000 digit changed to 0, but the 10,000 digit stayed at 1. As I continued to play it did rollover to 20,000 the next time though. It can happen at any 10,000 score level, not every time, but just enough to make it nearly unbeatable.

I’m not a technician or schematics whiz, so any detailed suggestions would be appreciated.

On a side note, what is the randomness on the 1000 point bumper? Mine light up and score, but sometimes they seem to stay on for extended periods, as compared to other times when you hit them for 1000 and they go out

Came home from work and cleaned up the L relay contacts and it’s working normally. I’m not a tech by any means, but I do follow directions well. Guys like you and DaMoib are a credit to the hobby. Thank you both!

Thank you to you and @woz. Everything working normally now after clean L unit.
You a both are both a credit to the hobby.
