Just replaced my mini playfield and I believe I swapped the two six pin connectors under the playfield. When I went to play the the mags did not work so on inspection I checked and swapped the connectors and now the mags work but the optos do not. When in battle the power mode the flippers are still working when just the mags on the upper playfield should be. Is there a fuse for just the mini playfield optos? Did I cook the optos by reversing the plugs? Is there a way to check the optos to see if they are still good or bad? Any help would be great. Thanks in advance.

Already checked switch edges and all other switches and optos on the game work as they should just the ones on the mini field.

Problem solved. I had an extra set of optos and that did the trick. Thank you all for your help.
