SOLVED - No Cabinet Buttons

[James]

WPC-S Game - WCS

Okay getting nothing on the Flipper grounded switches. This is on the opto side, will check EOS switch shortly and report back.

On the matrix I’m getting ROLLOVER 3 - Switch 63 triggering both that and TROUGH 3 - Switch 33

Everything on the cabinet is not working which I find damned odd.

That means nothing from:

Slam Tilt - 21
Magna Goalie Button - 12
Coin Door Closed - 22
Start Button - 13
Buy Extra Ball - 23
Plumb Bob Tilt - 14

Matrix says ALWAYS CLOSED - 24 and isn’t on matrix.

Closing EOS switch by hand does nothing. Jumping Start button (13) gives three noises but can’t see what atm whilst everything is plugged in.

Do you get an error message when you turn the machine on or go to switch test?

DO you have (or had) leaking batteries ? Do you have 12v at the opto boards.

Sounds like a broken diode (or a reversed one).....

14.6V at flipper bird one

 

[James]

Pins to ground testing them from the female connector obviously.

1 - 11.7
2 - 11.7
3-5 - 0
6 - 14.65

just hampering across matrix all is working so I’m guessing that but is off board

 

[James]

Yes has as battery leak but switch matrix seems to be ok...

Ignoring the rollover for a moment, all of those switches go through the coin interface board.

Try rows/cols on J1 then you can rule out the cable between CPU and this board.

I suspect it's that column feed to this board.

Which is where battery rot manifests itself. Clean and repair the battery leak first before trying anything else...

Sorted first issue, continuity from MPU header pins to cabinet coin door board not there, repinned all good.
