S-2000 Nightmare

[Incite Panic]

Good day to all:

      I'm completely stumped, and would like to kindly request any advice please.
      I have an S-2000 with a Coin-in-jam, and no functions on the player panel. I found it with an improvised coin in optic jumper. So I made sure it was the proper pin out, took out the player panel harness, and tried it in another game. It worked. I then tried the door senet harness. It works in another game as well. I have tried another MPU in the game, same problem. I have tried another backplane, same problem. I have swapped the power supply, same problem. I have disconnected everything except the front door harness, same problem. The harnesses tests good in other games. The I/O's test good in other games. The MPU, and backplane test good in other games. The meter board tests good in other games. I have ruled out the ballasts, printer, and BV.
      I would really appreciate any ideas on this.

Thanks in advance, and Kind regards:

Could possibly be a shorted button switch on the player panel

It's possible, but why would it work in another game?
I put it in another game, and there is no tilt, and the switches function as they should.
I should mention that I have also tried another VFD, and seven segment display.

So you're moving the microswitches along with the harness? How about the cabinet IO board? Might swap that out to

The "Improvised" coin-in optic jumper....
Can I see a picture of this?
I've made some of these for people and it's possible that yours is NOT with the correct pin-outs?

If you take a good high resolution photo of the jumper housing where
the wires are tied together - I may be able to spot something.

Do you have an actual coin mech and harness to plug in to try for now?


ADD>>>
I re-read your post and it looks like you've tried the jumper plug in another machine.
I'd still try sticking in a coin mech and full coin-in harness to see if that will clear the error message.

you might want to try unpluging your candle and other lights I had a machine once where i replaced all boards and wireing and the problem turned out to be a short in the candle I was so f'n pissed I almost broke the glass

Hello:

   Thanks very much all, for your advise, and your time. As for the candle that was discounted early off, as I too have seen that.
   I finally got this game solved after nearly giving up. I was using three bad MPU's. All three had the same symptoms. When I finally got a new one I tried it out of desperation, and viola.

Kind regards:

I could see one bad MPU but three of them? Holy Moly!
Thanks for the update! 
Karma to you!

I had the same problem and it was the I O  board on the door
