Am I understanding correctly that Y = continuity and N = no continuity? If so then switches 54 and 57 and stuck closed. The diode on switch 52 is shorted. Also the diode on switches 54 and 57 are installed backwards. Maybe when the diodes are reversed the switches 54 and 57 will not show closed all the time.

Then remove the diode on switch 52 and retest it, then replace it. Its only .05 cents. Check the diode band on 54 and 57 and see if they are going the correct way.

A pic is worth a 1000 words!^^^^

Looks OK to me... what am I not seeing?

If you look closely each tab on the switch is an individual piece of copper separated by fiber insulator block. The white wires are connected to a tab that doesn't have switch contacts at all, its there just for a connection point for the diode and the wire so not to be floating in the air.

You can put the green wires on the left, but then you would have to move the diode lead to where the green wire is now. Just look back at Terry's pic of the switch, white wire---diode non band---switch contacts---green wire.

Maybe the problem is with the other two.

There is 2 cut wires I see.

This is wired correctly. Check switch as Terry said and check the diode too.
