Quoted from Palealbino:My Demo man says check fuses f115 and f116, j112 and opto 12v supply. I checked fuses 115 and 116 and I'm good not sure where 112 is located and opto 12v supply. Any help would be greatly appreciated. I'm far from a tech on this stuff
Check your ribbon cables to all boards and reseat. I had this phantom problem but it seems like one of the boards isn't reporting the 12v back to the mpu and it thinks the fuse is blown. my claw moved back and forth a lot as well. I didn't do anything but reseat the cables and it went away.
