Can someone post a photo of the top center vuk from the underside of the Playfield? I need to see the switch and coil wiring.

Thanks

Thanks for the help. Mine doesn’t have two black/orange wires just one. Any chance you can take one with the direction of the diode on the coil for the center coil. I have one orange/black on one terminal and one red/orange on the other terminal. I’m having the fuse burn out in test mode and the mosfet keeps burning out also on the driver board. I bought the game like this so not sure how far this problem goes.

Lol...the second photo is close. The center VUK coil wiring and diode direction is what I need...the photo cuts off the wiring colors at the bottom the photo, and I really need to see the diode direction.

So I bought a Stargate with an issue that in WPC and DE games I would have fixed fairly quickly.

Fuse 28 and Q11 MOSFET on the driver board keep blowing as soon as I test them. Coil is new (top center kicker) and I’ve swapped the wires to the coil a few times (replacing the coil diode, MOSFET and fuse each time). I’ve tested for continuity and shorts and no issues there. Is there another coil or diode in-line that I’m missing? The Driver board is a new Rottendog board and the (top center kicker) coil is also new. I’ve tested the switch in the switch test and it works.

Yes sir that is exactly the photo I needed. Thank you!

So I got ‘er fixed...with a lot of photos provided by the member FtrMech which I greatly appreciate and couldn’t have fixed it without his help. I hope the solution helps others fix Gottlieb system 3 pins. So center kicker kept blowing the fuse, diode on the coil and Q11 MOSFET. I think I looked at everything and replaced all three of the above components at least 4 times. Then I looked closer at the fuse block and removed F26-F27-F29 and kept in F28...guess what it worked. I then replaced F27 and it still worked, then F28 and it still worked and lastly F26 and it didn’t work. I really don’t understand it but the coil that serves F26 still works and the diode is good but has a small short in it enough to blow F28??? Not sure why?

If you come across an issue where the MOSFET and diode are replaced and blow, take out the fuses that serves the same group of fuses and see if it resolves the issue
