Quoted from sohchx:Many thanks!! I've looked through both of these manual links on ipdb and don't see them unless I'm just completely missing it??[quoted image]
Go back to the schematics and scroll down to pg. 38-39. All of your circuit boards have a blueprint reference number. Your transformer is called A2 (see 1st pic). A2 has three connectors that represent what you are actually touching in your pin. Those connectors are J-1, J-2, and J-3

Down lower is the color code legend. This pic is of the Solenoid driver, also referred to as A-3. Down at bottom of this page you will see "Plug Connectors".

Go to connector address A2-J3-8. That is A2 transformer, connector J-3, pin #8. Next to pin #8 you will see a key plug in pin #7. To the right of A2-J3-8 you will see A3-J3-12. This is the address for Solenoid Driver A3, connector J3, pin 12. To the left of both of these address you will see the number 70.
70 is your color code. The color code table is at the bottom of the above page. #7 = red. #0 = no trace. So, the color of wire at A2-J#-8 is red. and the color of A3-J3-12 is red.
*******************************************************
Look at A2-J3-14. The color code is 58. #5 is white. #8 is black. So, 58 is a white wire with a black trace. And travels from A2 to A3.
Look at A3-J3-25. Color code is 64. #6 is brown. #4 is green. So, the wire is brown with a green trace. This wire travels to A3-J3-13. Again, color code 64. All this BRN-G wire is is a jumper wire that travels from pin #13 to pin #25 on the same connector.
Do yourself a favor. Go to Marco Specialties and get a nicely printed reproduction manual with the schematics.

A1= the displays wiring in your back box.
A2 = Transformer
A3 = Solenoid driver board (SDU)
A4 = MPU/ CPU
A5 = Lamp Driver board.
