501e control board diagram needed

[Hangry Vendors]

Hey guys, I have aninternet copy of the SBC control board wiring, but it is impossible to read. Image attached for reference. Does anyone have a high detailed drawing of this board? 
 

If not, I’m looking for the pin on the board that is the common wire location for the sold out switches. I can figure the rest out from there.

 

thank you!

If you have the machine in front of you grab a multimeter and test the harness. If the pinouts aren’t in the manual we don’t have them either, sorry.

It should just be the common wire from all of the switches.

The problem is I believe this wire is shorted out somewhere so this won’t work.

Yes it is the common wire I just need to know which wire it is

All of the wires are blue.  You need to go to the left side of the stack where the wires exit and look for a damaged wire.  They are fragile wires and the metal edges there will cut the wires if they aren't treated with care. There are probably numbers on the wires so if you are determined to find the common then just look for any common from the s/o switches that has a number, then you will look for that number.  All the commons will have the same number.  The NO and NC will be different numbers.
