Sanwa JLF-TP-8YT back and up switch are linked

for some reason whenever i do back or up it registers up+back. i don’t know how to test if it’s the wire harness or the switches on the stick itself (it’s in a modded madcatz SE stick).

i plugged in the stock stick and it’s doing the same thing, so it’s definitely the wire harness or the PCB. where do i go from here?

after a bit more testing it’s definitely the PCB.

i think your ground is wrong, it happened to me.

worth checking out anyway

Have you tried flipping the harness?

i found the issue. there was a teeny tiny piece of wire laying across some tracers on the PCB. no idea where it came from or how it got on the underside of the PCB, but whatever, problem solved.
