PRO THC Not working

Setting up a new Pro. The THC during test only shows voltage sometimes. Sometimes it gives a error code. Also, during the test, the fire button in firecontrol doesn’t always work correctly, sometimes it tells the machine to fire sporadically. Finally freezing firecontrol and causing and needed reboot.

If I remove the THC module in the controller the machine runs flawlessly. I have went through the troubleshooting guide and done everything aside from attaching the raw leads. Voltage of about 1.5-2.0 at the divided ports and cables all the way to the controller …even to the white PCB inside.

any help here? Thanks.
