Hey guys, need some of your expertise here.

My SW data East started needing a while to register drained balls. It got worse fast and then this happened after tri ball...

I left it alone so you guys could see and tell me what to check next so I can find root cause. Thanks!
 
There is a coil that kicks the balls over a hump to the coil that kicks the ball to the plunger. In the diagnostics, check the switch you took a photo of, then check if the coils fires (also in the diagnostics). Report back what you find.
 
It could be as simple as the metal tab on the switch needs adjusted so the ball rolling over it will fire off the switch. I seem to recall mine having a similar issue a long time ago where it would always think a ball was missing because that switch wasn't registering the last ball draining.
 
Check your ball trough....... Looks like a misaligned switch or foreign object is in there.
 
So I think the switch is bad, looks like a solder broke on the rear tab with the solid wire coming from the white wire.When I hold it against it the switch test seems to work better.

That wire going from where the white wire is first soldered to the rear tab has a resistor? on it? Why does this switch need the ground soldered in two spots? Why does it need a resistor? Sorry, clearly I am electronics challenged.
 
That "diode" is supposed to be soldered on both terminals like that. Keeps the 50V from spiking back.. Reflow the solder back on the switch and all should be fine.

Not a resistor, but a diode. It is in a switch matrix sharing the same wire as other switches. Without the diode blocking out signal from the other switches on the same line, all the switches would just register as one switch all the time.

Your switch looks fine. Resolder that diode and you shoud be good to go.

So the solder joint was definitely cold, but the switch is not great either. I couldnt find this switch on marcos, anyone know where I could order one?
 
the white wire is atleast soldered on.....I would have more concern with the green wire that is just pushed on. I'd pull that green wire off, clean the lug, make sure the green wire is crimped tight and put it back on and retest it in game mode. Hard to see in the picture but is the diode attached at both lugs?

So I found the switch on marcos, but it doesnt come with the diode. I assume I can reuse the same diode or get the same one at radio shack. And it just connects between the pos tab and the ground tab closest to the pos tab? Then the wires connect on the same tabs? Sorry if I sound stupid.
 
Thx all! I understand the wiring now too, i was wrong about the way it was soldered, the diode is just inline with white wire which makes sense. Thx again!
