I can't seem to troubleshoot my issue. My output fuse for my left flipper on the Data East Solid State Flipper Board keeps blowing (the coil never fires). I thought it may be the coil because I disconnected the coil and the fuse didn't blow so I replaced it and right after I push left flipper button, the fuse blows. The leds on the board are lighting up indicating that it is getting the response from the trigger. Any ideas on what can be causing this?
