Hi. I have an Addams Family Gold Pinball machine with some issues. I'm fairly new to fixing pinball, so please pardon my lack of expertise.

The original problem was the machine was indicating to check F114 and check F115 (a common issue from what I found out). I did properly test, diagnose and fix this issue (the connection from the 7812 to C2 was broken somehow, so replaced C2 and hardwired a new connection between the 7812 and C2). Unfortunately, during my diagnosing of the problem I made a rookie mistake when checking voltages on various boards and created a temporary short on the flipper board (which might or might not have caused the issue below).

So, with the F114 and F115 fixed, TAF now as the following problems:
* the main flippers won't work, but the flippers on the playfield do work (I'm guessing this is because of something caused by me creating a short condition during troubleshooting)
* I'm getting the following switch errors
- Bookcase Opto 1 -4
- Thing Opto Up (switch 85 I think)

I've checked all fuses and all fuses are ok. I thought fixing the WPC was hard but I don't even know where to start on this one!

Help

Yes, I checked all voltages on WPC and they seem ok. All lights on WPC are lit appropriately per the manual.

I checked the fuses (on the WPC board...that is where they are for the flippers), and all ok

Go into diagonostics-switch edges, and when you press on the flipper button slowly, the right flipper button should activate, then as you push in further the UR flipper button, and immediately the UR flipper End of Stroke. Same thing on the left side.
If your flipper cabinet switches aren't registering, it is likely to be the 339 chips on the fliptronics board, but it could be that the optical flipper button switches aren't getting +12v power.

The flipper switches are registering ok (although the UL flipper end of stroke doesn't always register, even though both the UR and UL flippers work fine)

The other optos - on your 7-opto switch assembly board under the playfield, the LED should be lit.

Yep, the LED is lit

When you go into diagnostics - single switch and use the + and - buttons to move over to switch 53, there should be little boxes around 53 (Bookcase Opto 1) through 56 (Bookcase Opto 4), and very importantly 57 (Bumper Lane Opto).
If Bumper Lane Opto has a nice little box around it, that tells us something, so check that, and get back to us!

When I go to Diagnostics, single switch, the following switches are CLOSED
15,16,17,24,45
53,54,55,56,57
82,85 (thing is up, bookcase is open)

Also, if Thing's hand is down, there should be NOT be a box on 84 (Thing down opto), but there should be a box around 85 (Thing up opto).

Thing hand is up and there is a box around 85

If all seven of the seven-optos run by this board are all out... well usually the game complains and tells us to check F114 and F115! The seven optos it runs are Bookcase 1-4, Bumper Lane Opto, Thing Up Opto, and Thing Down Opto.
Finally, check on the lower left corner of the Power Driver board, all four plugs should be plugged in (J116, J117, J118, and J119).
Let us know what you find!

Yes, all four plugs are plugged in

Other ideas?

btw...I also tested the bookcase switches and they register when I hit them. And tested bookcase and thing functionality via the tests and they also work.

Thank you! So is there any way to test the fliptronics board?

And I assume my problems with the bookcase opto 1 - 4 are a completely separate issue?

I created a different topic on this, but does anyone have a picture of the WPC board (12697-1) on The Addams Family Gold, that shows all of the connections to that board? I recently removed the board to fix it and did label everything, but didn't note which connectors were empty so I'm concerned I put some back in the wrong place (i.e. mislabeled). PI just am trying to rule out that I might have put connections back incorrectly.

Basically, I show the following connections are empty on my board once everything is connected:

J104
J128
J129
J131
J123
J124

I'd love to also get something that says what each of these connections is for if that exists as well!

so....after a good nights sleep after a day of frustration...

I unpugged the WPC board again, replugged everything, replugged the flipper board, etc., everything worked! So it appears that my only problem was the original F114 / F115 fuse issue (which I did have to fix on the board).

Thank you LTG and PinRetail for your help! My machine is as good as new now!!!
