Hi all
I’ve spent over 5 hours trying to figure out what’s wrong with my MB original Drac.
The game was working fine though Drac was moving a bit slow.
So I decided to clean the motor, stupid mistake because now it doesn’t work and there seems to be no solutions online.
The grease inside the motor was quite gunky. I’ve put it back together and when plugged into the board it spins on startup.
However I keep getting errors about Drac position 2 in particular but seeing other positions too error out.
The motor spins on Drac test but keeps trying to spin at the end or beginning of the cycle, it won’t move during Drac test unless I manually move it.
I checked the switch edges and all 5 optos register fine.
I’m pulling what little hair I have out, what am I missing here????

Had a similar problem. Tried all the things you did. Turned out to be a problem with the opto board.
