I'm pretty new to this site and a few months back purchased my first pinball machine. I'm hoping somebody can help me with an issue I am having.
I recently removed the ramps and plastics from my pinball and waxed the playfield. I also replaced all the bulbs with new LED bulbs. I ran into an issue with the flashers always being on. I found the thread https://pinside.com/pinball/forum/topic/removing-warming-resistors and soldered the ground from the flash boards. This fixed the flashers always being on issue.
My next issue was that the slingshots and pop bumper did not work. The game displayed error 57 which linked me back to the left sling. I went through and replaced all the fuses on the game even if they were good. Error message 57 no longer displays, but the pop bumper and slings still do not work. I confirmed that neither slingshot nor pop bumper fire during the coil test. They also do not provide any points when I test them.
Any help to resolve this issue will be greatly appreciated.
