Check wires on J6 at the coindoorinterfaceboard, Wht-Yel and Grn-Brn (2x)

The break was mid-production. So samples and first-half of production have one switch there at the coin door ('memory protect'), while later half of production have two. ('memory protect' and high-voltage cutout.)

I'm quite sure there should be a 2nd Grn-Brn on J6-7, can you follow the one from the tilt-bob assembly to J6 and see where it goes ?

Ok, my TZ does not have a coin door switch. So where does this machine fit in?

Means it was made before sometime in September, I believe. (Don't quote me on that, I'm running on faded memories.) In effect, your game was made about in the first half of the games that were made.

NO coin door switch? That doesn't make any sense. Coin door switches had been on tons of titles since well before TZ. Why would his game even get one?

Maybe it's just not mounted? Could it be hanging just inside the door?

High power interlock switches aren't on all games, especially pre TZ.

First third of TZ's didn't have high power interlock switch, only memory protect switch. Middle third of TZ's had high power interlock switch, but not wired in, last third of TZ's had high power interlock switch - wired in and working.

Right, but no matter what, there should be at least 1 coin door switch, correct? That was my point.

No where are there switches, high power interlock or memory protect.

And he has one. In post #6, you can see a picture of it. White switch, two wires to it.

I apologize. You were responding to apc7654 and not the original poster. Since you didn't quote him, I thought you meant the original poster.

Ok, some more questions,

in switch test,
-does the start button sw#13 work ?
-is sw. 24 'alway closed' present in the switch matrix ?
-does it trigger 'plumb bob' sw#14 if you put a wire from Wht-Yel to Grn-Brn ? (careful ! don't put it on the red wire !)

If it does trigger sw#14, the problem has to be found in direction of the tilt itself, maybe a bad connection to the assembly.

No worries! Sometimes I forget to direct my responses by using the quote features properly. But yes, I think it's extremely odd that apc7654 doesn't have ANY kind of coin door switch.

Well guys, I feel like a complete idiot not noticing the switch was located down and around the corner from the door. I was looking for the switch where others have pictured it at the top left of the door. It was the above quote from Miguel351 that made me take a closer look, and this is what I found....

Yep, you have a Coin Controls door on that game, not an Entropy door.

The switch is low on that door because it was designed for a top-entry bill acceptor/stacker.

Clean the corrosion off the plumb and ring. The dirt is keeping it from making an electrical circuit.
Short the wires on the top and on the ring of the plumb to prove the wiring is good. then you know it is the dirt on the plumb and ring itself.

This sounds correct

Has to do with the opto interrupters. There are two different lengths on the interrupter for the two different opto circuits of the two different flippers. The one for the bottom flipper "uninterrupts" the beam first, then the one for the upper.

Same operating principle as the more mechanical version of the double flipper switch found in a TAF.

The pros practice finding that spot(where the upper flipper engages) on each machine they play in a tourney to be able to trap a ball below, but still use the upper for the jackpot shots. It's quite the thing to watch!

You can see the step in the interrupter. The top opto will conduct first slightly before the bottom opto.
