"Test Switch Return 2-6" error on Freddy machine

so after frying some boards and getting them repaired, I now have an almost functional Freddy machine. before me swapping two connectors, everything was working fine on the machine.

now, when the machine boots up, i get a "test switch, return 2-6" error. i checked the schematics and this is all controlled by the A1 main board. if I unplug the P5 harness, the errors go away.

that is as far as I can get on my own.

any thing that a noob like myself could check?
 
any ideas? I'm thinking that since I plugged a Power Supply harness in to the Driver Board (and vice versa) that its probably a bad driver board?

also, according to the manual, it says that if some switches arent working, to check voltage <0, the main board OR the DRIVER BOARD so it would make sense to me that the driver board is likely the problem.

any thoughts or ways to verify this?
