I’m no expert in this stuff but doesn’t this path that I marked look bad and needs a jumper like the pins next to it that they jumped already?

It looks like they connect from the source at J6. Pins 1&2 and pins 6&7

Quoted from Flynnyfalcon:

Trace jumped, board replaced and problem still there

Maybe you need to re-pin all your connectors or give them a close examination to make sure there’s no breaks at the wire. You did mentioned you fiddled a connector here or there and got intermittent success on the lower Playfield lights. You said you have continuity throughout board and fuses are all good. You might have a loose connection at a harness.

I know what your saying but I had similar problem with my early solid state. Every once in awhile I would lose power to something and I would wiggle a connector and nothing would happen. Then I would turn the machine on and off and it would be fixed. Played several games and all was fine until it would fail again probably from vibration. Once again I would wiggle harness and this time it would fix it. Even pulling the harness off and reseating it would sometimes fix it. Finally put new pins on the end of the wires and it seemed to fix the issue for good. I’m not sure if the wires were actually broke or frayed but I’m thinking my problem was that the pin connectors were just stretched open from being pulled off the board over and over and were not making good contact to the actual pins on the board. I hope you get this baby up and running. I’m jealous, I really want a whirlwind of my own badly.

Also, my tech guy said that the connector in first pic doesn’t like to play nice all the time in earlier machines for some reason. He prefers the straight pin to pin crimp connection in second pic versus the punch in connection. From your earlier pic of lower GI relay board it appears you have the latter? Can’t tell for sure. But then again he could be referring to machines older than yours

Quoted from GRUMPY:

Your tech is saying that he prefers Molex connectors over IDC connectors. I believe most if not all solid state machines came with IDC connectors for there speed in assembly.

Thanks for the clarification Grumpy as I wasn’t sure of the proper terminology. But since the IDC connection is essentially a wire being pushed thru razor blades to cut thru the insulation and make connection, is it possible that Flynnyfalcon could have a wire that broke at this point from time, vibration, heat, someone being an animal and setting it too hard, etc? And by the way, my Orr Power Play is all molex so the tech could have been referring to early solid states.

Thanks for the info Grumpy. Always welcome learning new stuff

Quoted from Flynnyfalcon:

Powered back up...!!! And all the backbox lighting works!!! But the lower still doesn’t

How many hours have you spent trying to figure this out? This has to be killing you! I assume once you get it figured out she's getting bolted to the floor until the day they bury you in it
