Quoted from Robotworkshop:After reading up on the scoring I think I need to double check the adjustments on all the contacts for the number 9 positions. If one of those contacts isn't making a connection or not opening then that could be part of the problem. Should have some time tonight to check them out.
Two reels scoring at the same time is almost definitely a 9 position switch. The 100s not carrying over to the 1000 could be a 9 position switch on the 100s or also a switch on the 100 point relay that supplies power to the 1000 reel at that point.
