I'm putting my WCS94 power driver board back in after service and a couple of my labels for connectors have rubbed off.
The issue is that they are identical: J116 & J118. They are not only keyed the same, the have the same wiring:
J116-1 Key
J116-2 Gray-Yellow, +12VDC to playfield
J116-3 Black, Ground
J116-4 Not Used
J118-1 Key
J118-2 Gray-Yellow, +12VDC to cabinet
J118-3 Black, Ground
J118-4 Not Used
I don't know how to tell which goes to the cabinet and which to the playfield.
Any ideas how to tell the difference???
