Fixed one problem and another surfaces. Slam tilt resets on the Getaway.

Oh shit forgot to mention. Unplugged the bottom cabinet slam tilt. Still slam tilts. The one on the coin door I bent so far apart its literally impossible to slam tilt. So definitely not either of the switches.

Quoted from sixsixtie:
It seemed to me like it was always when it was in the pop bumpers.

It sounds like the common WPC reset issue with BR and Caps,But I would first locate the slam tilt switch on the switch matrix chart in the manual.Put the game in switch test and activate each switch that is in the same row as the tilt switch on the chart and see if any of them trigger multiple switches.You might have a bad/faulty diode or a loose wire on one of those switches.

Sorry. Just want to make sure so I can be extra focused next time I go out.
But I should go through and test all of these switches in single switch mode and if any of them activate two switches then that's the problem?

That's correct,Test each one all the way across the chart in Switch test to see if each switch registers properly.

I'll bet it's that top jet. if you say it happens in the pop bumpers.

If we listen to the symptoms carefully, it is clear this is definitely not a standard wpc reset problem. The game is not power resetting. It is not a BR2 or whatever problem. Instead, the slam tilt is triggering and a slam tilt game reset is occurring. This is the report we are given. The two are extremely different and diagnosing the two problems are totally different.

If it is a slam tilt reset problem, I would physically disconnect both slam tilts just like you did. Next, I would run a switch test and trigger pop bumpers and every switch and see if any of them also trigger slam tilt. If so, you can trace it via normal switch matrix debug. Could be a bad diode, bad u20, etc. the switch test is really your friend here.

The problem seems to be in the Streetlight targets in the pop bumper section. When the lock is lit, and i press the green light target, it slam tilts 100% of the time.

sincerely the guy who has sixsixtie's machine at his place.

So switch 51 triggers switch 21? But only if lock is lit? I think if it were a diode / wiring problem it would trigger all the time with lock lot or not. You verified this in switch test mode by pressing switch 51 and seeing 21 trigger? You see only 21 trigger or you see 51 and 21? Or more? Might be a bad row chip U18 on your CPU board or even U20.

If you can reproduce it in switch test mode, I would remove the switch wiring connectors from the CPU board and manually short the switch 51 row/col and see if the sw21 triggers then. This eliminates playfield wiring.

Of course I have enough games that I usually swap CPU board from another game to eliminate the wiring but you may not have such a luxury.

Ok so I was just on the phone with CDT. He was in the switch edges test and he says when he presses the top green it flashes Green/red before going to green/black. So that's definitely the problem. But he says that during game play you can press 51 all day and it won't slam tilt UNLESS lock is lit.

Could this at all have to do with my up/down ramp too? Its always been going up and down when lock is activated. (lock being activated is the same precurser to the slam tilt reset)

A while back I noticed a real hodge podge diode on the up/down switch. I replaced the diode but it didn't fix the ramp problem and now Im questioning if I got the polarity right.

Could either of these issues be related?

Sounds like classic switch matrix issue, start with the same row and column the slam tilt is on, then move onto other switches.

Switch wired wrong, diode on backwards, short to switch wiring.

Yeah but thing is its never had the problem before so how can it all of a sudden be a switch wired wrong? And the only diode I've ever touched was on the up/down ramp.

Did you test any diodes on those switches with a meter?There is one switch that is an opto on the same row as the Tilt switch,Did that opto register in switch test?

Yes I just replaced it to fix the supercharger problem I was having. SC now works fine. I havent been out to check the diodes on the other switches.

It could be a transistor failing. That's why other switches in the row will trigger the wrong event.

Bit of an update. Got a chance to go out there today. I'm definitely going to have to have someone come in. In over my head just can't figure it out.

Basically the only thing I figured out for sure is that if the ramp is in the down position as soon as you press the top green it slam tilts. But the ramp HAS to be in the down position. I have no idea how or why it's related because it seems like it's in a different column on the matrix but it slam tilts 100% of the time when the ramp is down and top green is pressed and 0% of the time when the ramp is up.

Outside of that I'm basically lost.

The ramp down triggers a switch, which one? What is its row/col compared to slam tilt? Is it somewhere in column 5? (52, 53, 54 etc)? Or column 2 (22, 23, 24 etc)? Sounds to me like a diode related issue. Perhaps you bent the a diode to short across a switch pin or such while you were installing the new part.
