Another EBD switch matrix issue..

Just brought a beat EBDle back to life and am dealing with a few things... I will happily ship beer of choice in the mail (like I have done for others here) for help!

-When the 2x3x4x5x bank resets it fires the 2,10 drop coil.

-Roll over/trigger 'C' OR 'D' and they both count, but it will score properly for just the one lane.

-When I make the saucer and it pops the ball out, the game tries to eject another ball. (Maybe I have the only multiball EBD on errf?)

I have replaced the disk caps and/or cut a leg off to test based on other posts I have read. I have not messed with diodes yet but did look everywhere and made sure they were not touching anything, all original and no resoldering on any. - I'm sure thats where the problem is but I have no manual and a very low IQ.

Things to mention. The coin door innards have been removed, wires cut. There is a rigged switch with diode (matches my Centaur coin switch wiring) that you press to add credits (with or without that connected, the same issues occur). All other wires are separated and are taped up.

Lights.. The 'L' on Deluxe on the back box, the 4 insert near the drops, 50k near the Bankshot and the 2x by the flips, all dead yet there is power on the braid, all solder good. - I assume this has nothing to do with the matrix issue, but again, I'm not too bright.

Hopefully someone can push me in the right direction. Thank ya!

I think you might have a bad diode on the 2,10 drop coil or a wrong coil (without a double diode).
(see the image below)

This is an option which can be set via dip-7 on the MPU board.
(see second image below)

This might be the same kind of problem as the drop target, but then at the outhole coil.
Again this outhole coil has to be a coil with a double diode. (also visible in the first image).

The lights have indeed nothing to do with the switch matrix.
You are brighter than you think.

Check the voltages at the lamps which are off.
You said there is power on the braid, but do you also have power at the other wire comming from the lamp?
This would indicate a lamp (or socket) being bad if there is no power on the colored wire.
If you have power on the colored wire, you may have to look at the print header(s) of the lamp driver board.
Most of the time they are cracked.
Reflowing the solder joints at the print headers solves 95% of the problems with Bally SS machines.

I hope this helps.

Thanks for the tips! Here are a few pics of the coil/diodes. - Also, I noticed the brown/orange wire was taken out of the harness so posted pics of that too. Is the outhole coil wired properly (I will hunt for info on that now)?

I am following that 'solenoid misfire' post, just seen it this morning.

I spotted your problem with the drop target.
There is a wire in the wroung position.
The red arrow is the wire in the wroung position.
It should be at the green arrow.
Just look at the wires in the green circle.
Those are correct.

I can't tell for the outhole coil....
I need to see the diodes and the wires connected to it.

It WORKED, fixed all issues (but the few lights which I can monkey with)! - I owe ya! Can't ship beer of choice that far safely but would happily make a donation in your name?

Thanks again! I'm borderline neanderthal when it comes to matrix issues so appreciate the detailed help!

Spoke too soon like many others with this damn switch matrix crap! - It worked great for hours, now every time a game is started the 7 drop switch is triggered, the drop itself doesn't fall...just the switch. It's like it takes the machine being on and played for a while then the phantom 7 switch begins. I didn't notice any other issues while playing..

I will check out everything inline before it and hopefully figure it out before I fix it with a sledgehammer and a full bladder of urine.

BTW, you now have a little heart next to your name.

Check the diodes on the drop targets.
See if there is a splatter of tin on the switch stack.
