Hey all,

Rookie here... my Mary Shelley's Frankenstein suddenly gives out two balls in the shooting lane instead of just one. How is that possible?

I'm not sure if the problem lies in the sensor/contact parts the balls lay on or the opto board.

I removed all balls and then reload them, which had no result. How can I find out if the six sensors below the balls work?

Thanks!
Steven

Hey Steven,

That usually happens when there are too many balls installed in the game, but I don't think that's the case here.

Have you run the switch test yet to see if all switches near the ball through work correctly?

The title of this thread is awesome.

You'll get an answer to the question tomorrow I am sure. Just an opto issue. Does the ball end when one ball drains when two are in play?

Go into the switch test mode in the settings. It will show a picture of the switch matrix on the DMD and lit squares will correspond to active switches

Just did the swith test (all the six balls are in) and the only thing that the display shows is:

ACTIVE SWITCH TEST
6-BALL THROUGH #2 (#3, #4, #5, #6 (F))
GRN-RED WHT-RED (ORG, YEL, GRN, BLU), #10 (#11, #12, #13, #14)

So it doesn't show #1. Does this mean there's a problem with #1? On startup of the machine it says one ball is missing, while all six balls are already in.

I didn't see a picture of the switch matrix.

Thanks again, guys!

My IJ (Williams) done the same thing , the opto ball trough , the 2 PCB's get a lot of abuse and vibrations from the draining balls and the optos can just crap themselves , or get cracked soldered joints , I did use a camera to check the optos for proper operation , some we're very dull ... Sometimes it's just the best to replace them ( The 2 PCB Boards ,remember these original boards are like 20 years old) as the new hardware is much more reliable ..

Okay, thanks! I understand what you're saying, but I'm afraid I don't know how the parts look like you're talking about.

So, I have a few rookie questions: how do I recognise an opto ball through and how a PCB?

I think Frankenstein trough will be considerably different, but basically this is what Buzzbee is referring to.

I think Frankenstein uses regular switches to account for the balls in the trough.

Williams/Ballys, like Indiana Jones and my STTNG (I replaced these boards this morning) use optos (beams of light) to account for the balls.

I would imagine this is more of a switch issue than a board issue personally. Then again, I don't know shit for the most part either, lol.

Wow, thanks for the pics! Aha! Now it starts to make sense. Indeed I have switches the balls lay on. So probably one of the switches is bad?

Does this has anything to do with my active switch test result, that #1 is missing in the list?

Here's a pic of the switches Frankenstein has!

Remove the balls and trip the switches by finger.
#1 will not register, look if wires are all soldered on, not loose, or if the solder is not cracked or dull (re-flow solder).
See if the actuator-arm on the switch is not bend proper.

Veel succes, maar dit moet te repareren zijn

Okay, thanks a lot! Een beetje solderen moet wel lukken!

Cheers,

By the looks of it, the first switch is most likely not fully pressed down.

I just had to replace the last switch on the Frankenstein I'm working on. Switch lever was bent and the ball sometimes wouldn't register, which would lead to 2 balls being ejected at times.

Thanks for the pictures to clear that up , yeah I hasn't sure either if it was Optos or switches ..... Now I know .

Okay, I did the switch test and at first, the most left switch didn't react. I pressed it down a few times and then it worked again. When I looked more closely, I felt its middle metal move a bit, so this it it!

Thanks a lot guys. Another part of the machine I understand!
