I have been slowly restoring a Subway I picked up a few weeks ago. I have a issue with what appears to be a 1s scoring issues. If the 1 point reel is on any number except zero the machine will reset fine, as soon as I score anything from a 1 point switch, the N relay in the backbox will lock on with a loud buzzing and the score real will not increment to the next number.. If I manually press the plunger on the 1 point reel to increment the reel, the N relay will reset. This will continually happen.. Note that 10 points and 100 and 1000 points are not affected at all.. only the 1 point switches.
Also, if the 1s reel is at the zero position when the machine is powered up, everything will reset but the N relay will be locked on until I manually press the plunger on the 1s reel to increment the number, but like i mentioned, if the 1s reel is on any number EXCEPT the zero position when powered up,the reel will reset to zero and the N relay will not lock on until I press any 1 point switch, then it will lock on until I move the reel to the next number.
Just a note, I replaced the flippers and pop bumpers with high powered coils, but I dont think that should be a issue. I also moved the power from Hightap to normal as it was on Hightap when I got the machine.
Thanks for any help you can give..
