My Who Dunnit pinball has an error message (check fuse f16 or 12v opto power) first turn it on about 30 seconds f16 fuse blows now if I unplug the three stepper motor boards the fuse holds. Now hears where it gets strange if I plug in just one of the stepper motor boards it doesn't matter which one the fuse blows.
I have already swapped out the power board and the cap on the opto board which was leaking
Can anybody help me out
