I was having problems with my 10 point scoring reel not working all the reels would reset but the 10 reel would not change score well I was looking at all the points relays in the back of the head and I notice that some other relays had solder jumpers from switch to other switches on the same relay so I notice that on the 10 point that one of the switches only had one wire solder on the top of the switch so I ran a jumpers to the next switch down and it works and scores when you hit a switch on the play field I never seen nothing like this before by the way its on a 1963 gottlieb gigi I am new to EM machines is this normal
