Hi Tim, yes this is Mike. I can not find any help near where I live, so I am still trying to resolve my issues. I believe your 100% correct on the contacts I need to look at. I have been finding these relays on my schematic, and then following the path to the switches, then matching wire color to switch to see its state.
what is happening right now, is when I plug in machine, before coin up, all 4 contacts on the game over relay are closed, when power is applied, the lock relay does not energize so this makes the game over coil drop out and the plate goes all the way to the rest bar, see picture.
In the picture you can see the 4 contacts. when I make the top front contact open on power up than the lock relay coil energizes, but does not always make its contacts correct, it has a really weak spring and a little stronger spring makes it worse. I can make contacts by very lightly touching the coil plate. I measure coil resistance with the machine unplugged and get .88 there is the same coil in the game regulation relay which measures the same, so I was debating on swapping the two for testing. So I am not sure, if it is a coil, or maybe another switch like in your response that is not quite adjusted correctly.
I have seen some older posts with members here that have very, very similar united shuffle bowlers, in fact posts with partial shots of there schematics seem identical to mine. I was hoping someone with a machine like mine could jump in here so we could compare some switch settings and other items in machine to get me up and running. I can manipulate the contacts and switches discussed here to get it top reset on coin up, then nothing happens on the lane switches. I seen another post where someone else had the same issue. https://pinside.com/pinball/forum/topic/tech-help-needed-1#post-3612264
