I'm trying to figure out why double bonus doesn't work when my Top Score is set to 5 ball - it's supposed to give double bonus on the 5th ball but it doesn't. When it is set to 3 ball the normal scoring is 1st ball is standard bonus, 2nd ball scores double bonus and 3rd ball scores triple bonus. All bonus scoring for 3 ball works so I at least know double bonus works.
I have a schematic but can't figure out which relay or switch to look at for the last/5th ball to score double bonus. Any suggestions? Thx.
