Just to be sure.
The two white wires, are they both the same color stripe ?
The diode, are the wires soldered to the black end of diode and the silver band end goes to the top lug ?
Thank you.

Yes, both wht/brn on the left target and wht/red on the right. Wires are soldered to the black end of diode and grey end of diode to top lug.
Thanks for all your help, Lloyd. I'm pretty much out of gas myself working on this. I wish I had another board to try.
One other question. Is the game capable of correcting itself for the whirlpool exit error and diverting so as not to give that lost mine hit every time the ball goes thru the whirlpool? Because it's not doing that anymore.

Lost mine hit was something else.
One switch triggering another generally hints at a common switch matrix issue. Switch wired wrong, diode on backwards, or a short to switch wiring at a switch or elsewhere.
After a break and some rest, may as well look over your other switches in the game. something somewhere is being a real pain.

Should he start with the switches on the same row and column as the optos are on?

Doesn't matter, could be anywhere.
I even wonder if there could be a short internally or across fiberboard spacers on targets mucking things up.

I have checked all switches on the same column/row. No issues that I can see. I would also have to think that if it were another switch causing the problem, I would see an error with that switch. I need to learn the theory of how these optos, opto board and main board work together. Pinwiki doesn't offer much info as far as optos go.
Fix this yet?
If not, I suggest unplugging the J212 on the bottom of the MPU board and plugging it back in. If it works, then you will need to repin this connector. You could plug it in at an angle to make better contact if it plugs in loosely compared to other 3 connectors at the bottom of the MPU.
