I bought a nib IMVE on Friday. Soon noticed opto not working on war machine. Opto lights but switch doesn't register. Light board LEDs only glow red when power on/off game, or wiggle connector at tip of pins. Will not respond if seated. I've placed a new connector on with the same results. Used an ohm meter and seem to have good connections on all 4 wires. Readings are 1.6-2 from connector to back box. Not sure what that means. Took my board to the guy I got my imve from and he plugged it in and worked fine on his machine. I called stern tech and they had me leave a message, not sure how long that will take. What am I missing? I'm relatively new to this so I hope it is something simple.

Any ideas?
