In the club! My System 11A collection is almost complete. Anyways, the wires for the beacons and fuse were cut, does anyone have good photos of how the wiring looks for them? I have a molex connector that seems to be wired wrong?

The unused fuse block should have the white and blue wire from the relay board ground point then to the pointed side of the molex connector running up to the lights. Here are my pictures.

Thanks! The photos + your description is helpful. Now to figure out why my upper ramp diverter won't work. Totally stumped. Wiring is correct. Driver transistor is good. The diverter will fire when I ground the transistor. But it just won't work in test or game.
Quoted from GRUMPY:Use your logic probe on U-49 pin 1 and pin 2 in coil test. Do you have pulses? Yes, the check U-50 pin 1, do you have pulses? Yes, then replace Q-76. Let me know what you find.
It’s a Rottendog board. So that would be U11 pin 14. Tests solid low. The input side (pin 6) is solid high. This is during upper diverter test.
I actually tried another System 11 board in there with the same result for the diverter. The other board has an issue with Speech not working otherwise it would be in there.
Quoted from GRUMPY:What happens when you briefly ground J-18 pin 8?
If I ground the transistor, the diverter coil fires.
Quoted from GRUMPY:Where was this board from originally? It wouldn't supprize me if it's from a F-14. From what you describe, both boards are damaged in a similar manner.
If was originally in an F-14 also. I have a Pinbot and Millionaire board I could try.
Quoted from GRUMPY:You will have to install this board and troubleshoot it too.
So the Millionaire board works fine. I’ll enjoy F-14 for a bit before resuming the troubleshooting with the Rottendog and original boards.

The Rottendog board has a bad PIA (U_11D) that was causing the upper diverter to not work. Rottendog is back operational. The other board will be troubleshooting in a High Speed. Multiple special soloniods don’t fire so I’ll get out the logic probe again.
Quoted from GRUMPY:I think this is the part you would need.

That one looks a lot thinner than the F-14 one, plus the F-14 one has a bend in it. That being said, you might be able to bend this one so it is at a perpendicular angle to the playfield. "01-8772 Ball Deflector" is the part number in the manual, but Marcos does not have it listed.
Quoted from topkat:I took all the fuses out on the power supply. They tested fine and when I put them back... now the beacon power comes on. Don’t understand that..
Bad connection on the fuse clips / cold solder joint?
