s2000 board gurus I need your input please

[Nepa Coin Op]

I have a 2k board here rotted but not horrible Ive fixed worse, Ive done the mod on it to eliminate the door issues by adding the switch. I sill get door open B, can someone please tell me what traces or connections to look at that would cause that. I used to have the info on doing this mod and did it by comparing it to another here I could be of one pad or have a trace busted somewhere, any help is greatly appreciated

Thanks

If you did the mod door b should have been jumped directly at u69 if your still having the error with it bridged at u69 the varta killed u69
