Below is a picture of the top Out hole kicker switch( the one that's working correctly) note the locations of wire to the lugs.
This next one is the side Out hole kicker. There wired/soldered to different lugs. Is this the problem or is it just that they have different functions?
That diode in the second pic looks back to front, The banded side should go to the Lug with no wire attached i think . if you see what i mean . Try swapping diode around . Also the diode looks broken but is that just the lighting of photo? All other diode bands in your pics go to the unwired lug so hope this helps
In the 2nd pic it looks to me as though that yellow/red wire has been moved, in order to bypass the diode.. that diode would be doing NOTHING. I would be moving the wire back to the lug the opposite end of the diode (unbanded end) is soldered to, and replacing the diode.
the two lugs the wires are soldered to in that pic are the switch contacts, the 3rd lug is just an anchor point for the diode anode (unbanded end) and the wires, and just 'floats in the breeze' so to speak.
Solder the new diode back in just as the old one is, and move the yellow/red wires to the lug the unbanded end of the diode is soldered to. The original diode must have failed, and someone just said.."oh i'll just bypass it"
