Dear fellow Pinsiders,
I'm in the process of rehabbing the slot reels and assembly on Who Dunnit. When I got it, the owner said the slots needed new reel motors. Well, I order the new reel motors from sparkfun and installed them today. They still do not work. the left reel does nothing, the middle reel vibrates crazily, and the right reel does nothing. All 3 reels have been repaired with the 3D printed collars and new set screws, and the motors have had a flat spot grinded onto them so the grip the motor shaft perfectly and spin nice and free. When power on the machine is turned on, though, the right reel will NOT spin freely, but if I unplug the power connector to the PCB for that reel, it will spin freely.
I've read somewhere on Pinside about the IC chip on each individual slot PCB may need to be replaced
Any help would be great, this thing is driving me bananas.
Was wondering if the power driver board has anything to do with this.
Thanks in advance, Dan
