Quoted from ChrisHibler:

O. OK. Now I think I know what you mean.
But first, what do you mean by "errors".
Are the switches reported to have an error when you enter diagnostics?
You can try this.
Get a jumper with alligator clips on both ends.
Game OFF.
Connect one end to the white/gray wire on the rocket kicker switch.
Connect the other end to the white/gray wire on the lower right 5 million target.
Make sure those connections are correct and not touching anything else.
Power on.
Test the switches.
Report back.

Quoted from ChrisHibler:

We all start somewhere Rick. And we learn by asking questions. Good for you.
The test I prescribed will connect a known working on a switch in that row to a problematic switch in that same row. If the problem has been caused by a break in the daisy chain wiring for that switch row, this test will tell us. If the switches (or at least more of them) begin to work, then we know that there is a discontinuity. This is an old operator hack.
An equivalent test would be to set a DMM to continuity and "buzz" from a known working switch to a problematic switch. If no "buzz" the wiring chain is broken.
