Jamma Harness Player 1 Start wire not registering

[BOGOmargaritas]

I was wiring up the buttons and joysticks today to test them and I noticed the player 1 start wire was not registering anything. I have tried grounding the wire multiple times & cleaned the contacts. I stripped the heatshrink for the wire on the jamma connector and tried grounding the pin, but still nothing. Is it possible that the jamma harness connector is bad? Really hoping its not an issue with the board.

Thanks in advance for any info!

Probably not, but to make sure you could try grounding the edge connector on the board.

Sounds to me like a board issue.

Hey Nem. Since my post, I have tried grounding the contact on the edge connector and even following the trace to a resistor network and soldering a wire to the pin the trace leads to.. still no luck. Any chance you have experience with something like this?

Not really. What board is it? Hopefully it's not a custom that's faulty.

meter between the start1 pin and ground while the button is being pushed - just to confirm you only have 1 problem
