So I was working on my 1981 Stern Lightning, replacing a flipper coil on the upper playfield. I got it in and turned on the game tested it and blew 7amp fuse, thats when i realised I put it in backwards! AARGH! I thought no big deal just take it out flip it & replace the fuse. But after doing that the displays and the game still wont start up .... which way do I go now?
