Hello Everyone,
I recently purchased my first pinball machine a 1990 Bally Dr. Dude and was installing a trough light kit from comet pinball. I had the machine turned off and connected the alligator clips to a GI light below the playfield and when I turned on the machine the bank of lights I connected the trough light to with the alligator clips does no longer turn on, even without the alligator clips on them. It's odd becuase when I tried the other side it worked fine and the GI lights still turn on. Did I blow a transitor by chance? Any advice is appreciated on how to re lite these GI's thank you so much for any tips![quoted image]
