Is that what you need? These were all taken when the machine is on.

Only the LED 3 lights up, as shown in the first picture here.

Also, I had just recently unplugged the part below the power supply. It has the same effects if it is plugged in, I just forgot to do that.

All three of those LEDs should be lit... did you check the fuses?  Take each fuse out and use use a multi-meter to check them for continuity.

JODY:
Williams machines often have bad connectors.  Are there any connectors that are burnt or broken?  By broken, I mean an individual wire may be loose or broken with a connector.  The ones going to the power supply board are especially bad at doing this.  I have a Sinistar with one bad now.  Have not gotten around to replacing it yet.  Also, had a ground wire go bad within a connector on a Joust machine.  There is a lot more detailed information on the KLOV site.  You would need to check voltages on the power supply board, check voltages going to the RAM chips, various connectors, etc.  The ribbon cable going to the ROM board also goes bad on these.

Now just why do my posts keep disappearing? My recommendation to replace the electrolytic caps on the regulator board is *very* valid. The 3 supply voltages need to appear at the ram banks in a specific order. With caps on the way out on the reg pcb, the order they "come up" at can get altered and cause all kinds of goofy errors.

Do this now, or you can be chasing yer tail for a long time trying to track down a fault that doesn't exist.
