I just purchased an EBD and some of the drop targets are not reseting between players. When I do the solenoid test, 5 of the 7 memory solenoids are not firing. I removed the case holding them and the wiring looks strange. Can someone tell me if it's wired correctly? The two with the sloppy soldering on the end are the two that are working.

I checked the connections and everything looked good. So, I swapped out boards with my mr&mrs pac-man and same results.

I know it looks like there is a wire off, but it's actually attached to the diode on the underside (see pic). The strange thing is the two with the jacked up diodes are the only two firing.

Thanks everyone for all the help! I will dig out my volt meter and see what's going on.

The problem has been resolved! I traced the power wire back and found that the solder joint had broken and the wire was hanging. I soldered it back and everything is working! Thanks again for the help, much appreciated!!
