If you click on the pictures and make them larger you will see the pin numbers I put on them. Are you using a computer or a phone? You wanted to know the pin numbers on the switch, so I numbered them and gave their destination
I used the pictures you provided, and numbers the pins as per the service manual
Pin 6, To Board 15 (Left Output) goes to the amp board, pin 15
Pin 5 goes to Left speaker "A" + positive (Red terminal)
pin 4 goes to Left speaker "B" + positive (Red terminal)
Pin 3 is not connected (n.c.)
Pin 2 goes to Right speaker "B" - negative (Black terminal)

R_J, are you saying that the numbers are on the white circular thingys in the center? I do seem to see what look like faint markings on them. I will check this out further.
Thanks much, you could be a life saver because it never occured to me to look there.

Can you see these numbers? the switch pin numbers count around the other side up to pin 12

Oh heck, I thought you saw the numbers on the switch somewhere. I'm sorry, instead you were telling me where the pin numbers are, geeez, I'm such a bonehead. Now it looks like I may have been wrong in my assumption. How could you tell what number the pins are? I mean the switch has a notch but is #1 pin to the right or left of it or not at all? I'll need to know so I can work with these in the future I have 3 more of them. Thank you very much I really appreciate it.

Well I should say I hope you are right because none of th wires you picked were in the right place on the speaker output terminals, so I'm going to rewire the speaker output terminal section just the way you listed them. You were dead on with 15 and 16 going to the relay board so I guess everything else aught to be okay. I had been thinking for a while now that somebody got in here and messed up this wiring, mainly because there were no wires on B negative left or right just the jumpers for the A + B which if I am correct should go from A- left to B + left and A- right to B + right? Thanks very much for the help R_J.

[DrDos]

After studying what you gave me I mapped everything out and found the only wire missing was B + right and A- Left and I assume those are the jumpers from A- right to B+ right and A- left to B+ left to complet the A + B speakers selection. If I am right then you were sent to me by God J_R. Thanks. I am learning so much. I may even take a short beginners class course in this tuff to get better at reading resisters and stuff. Thank you.

[DrDos]

Sorry to bother but I thought that the notch on the wafer meant pin 1 to the right, but that is not how it goes so how do you know? I mean where is the benchmark for wafer switches so a person can find pin 1? Your wiring is totally different than what was there which explains why I had music coming out only one A or one B I guess once I got it up and running. Teach me how to tell where pin 1 is located on any wafer switch please?

[R_J]

I went by the schematic, and the one giveaway was pin 3 which is not used and is not connected to anything. I am not sure how alps numbers the switches, but in this receiver, this is how they are numbered. It looks like this switch has the mounting bolt between pin 1 and 12. This switch was likely custom made for Kenwood

[DrDos]

Wow, that pin 3 did not even come into my head, amazing. Well, at least I did learn something. I'm going to print out the pics with the numbers you put on just for future reference. I really do appreciate the work you did for me. Thank you very much. I will post a pic of it in the lets see your Kenwood thread and gice you credit. Cheers!
