WMS Model 400 Wiring Schematic
« on: November 24, 2022, 07:22:13 AM »
I have recently aquired a WMS High Speed Slot Machine with issues. I thoroughly cleaned everything in the machine and found no indication of problematic wiring or boards. When it powers up the lights come on, no sound, and the board shows 1 red LED lit (+18V). The battery is also bad and needs changing. From limited info found I will change the PS to an ATX 400 watt and replace the battery. Am I headed in the right direction?

So...does anyone have or know how to get the wiring schematics for a WMS Model 400. There is an image of a publication titled "WMS model 400 Slot Machine Drawing Set", but I cannot find anything anywhere. I even found the person that wrote the manuals and he didn't know where to look. He did provide some very interesting history into the development of the model 400.

Happy to find this site!

Desperately seeking schematics for the Model 400,
