Hi all, just purchased my first pinball a couple of weeks ago and having a great time playing and learning about it. I thought I would try an led conversion which was going great until I installed the new led flashers in the playfield area which failed to work. The guy I purchased them from said that as these flashers are 12 volt items, I will have to reverse the polarity to get them to work. As I am totally an amateur with any sort of electrics, just wondering if this advice is correct and if this means I have to switch the wires on each flasher housing. I would have thought there were direct replacement items. Anyone know where I can get plug and play led flashers for this gottlieb classic. Thanks Anthony - australia
