I was thinking CPU like PC. Figured it was on the face plate board. So I'm on the board that has tge ribbon cable and pin 22. Let me recheck 111 and 112

Yes, so I guess you were not on the same TR111 and TR112.

R170 has 4.78 on left ribbon cable towards front of unit. Other side is 4.77
Tr111 has 4.76 on left pin. 0.00 on both right side pins
Tr112 has .75 on bottom pin. 4.78 on left top towards front. 4.77 on top right towards back of unit

On TR111, do you mean the side with just 1 pin has 4.75 and the 2 pins on the other side have 0?

Ok, power is definitely not being turned on. I have to look over these diagrams for a little while to see whats up. In the mean time, if you are able to test at CY124 (12 pin connector) I need you to test the voltage of each of the 12 pins. Leave your ground where it is and just probe the connector and give me the list of voltages per pin.

I can but what board is that connector on so I'm in the right spot this time

The units still fully assembled so I'm having a hard time locating that connector. I see a few 12 pin connectors but none are cy124

You were already on it when you tested the +6v. It is on this same board we are working on with pin22 ground. It's in the middle of the board.

Where is it in relation to connector cy117

I think it's the one below it 1/4 and to the right an inch. Or it the one with the wire you had me cut

Think I got it. It's the connector that has the thin board that shoots over to the power supply. Everything is zero except for three pins. Pin 2 is 5.65. Pin 7 and 8 are 5.40

Go back to page 11. I already posted the picture of it. Double check and make sure and let me know.

Yes I had the correct one. That was how I found it on your pic

Ok, back to the connector on the top of the board, CY272. Test pins 16 and 15. 15's voltage may be fluctuating.
