Quoted from Seamlesswall:I understand that. But these two are not reading zero. they are reading open. Why? My question is if I jump them what will happen?
W1, W3 & W5 should be jumpered for +25v & +50v coil operation. They should not read open. If W1 & W3 are open, replace with a wire jumper.
I am guessing your 0 ohm resistors may have just cracked, and your problem behavior is due to not having a spikeback dump available to it. These would not likely blow open like a fuse unless they were really cooked, in which case you'd have a lot of other board issues, blown diodes & transistors on aux board, etc. But please take this info with a grain of salt and make sure you probe and test components on those +25v & +50v lines. I don't want to be the guy that gave you the go ahead to blow up your game.
