Hi
So I've gotten everything working, except the sound is very muted, and overlayed with static (both game boards give same result).
I tested the wiring between the connector in the CP and up to the speakers, all four wires have continuity.
From the JAMMA harness the grey has continuity to the speakers but not pink. I followed the pink wire and it goes to the PSU to the plug named SOUND OUT. Does the grey one also go from the harness plug to the PSU and if so, how do these and the blue striped pink and grey that also go into this plug relate? As in I know four go up to the plug in the CP but how do these fit in with the harness?
Tldr; is this pink one not showing continuity between the harness pin and the speakers my problem? I'll stop typing, it feels like I'm rambling.
