My idol on my IJ Will not stop spinning checked all optos,wiring and plugs.i'm thinking it's the 8 driver PCB bored.there are two LEDs on it a 12 v & 5v only the 12 V is lit. Is the 5v supposed to be lit ????. I checked the 5v coming from the power driver board it's showing 5 V going into The 8 driver PCB ( at the plug )but again LED is not lit. Any help would be appreciated thank you
