Quoted from johnboy1313:The new board says "5A FB" for the same circuit. This was supposed to be a direct replacement. Did I get the correct board?
5 amp fast blow at F4 was the default for Bally/Stern games that had two flippers. For games with 4 flippers a larger rated fuse was needed. I guess Stern stuck with the larger rated fuse for lower B.O.M. I can't see any other reason.
Since Quick Silver is a two flipper game I imagine a 5 amp fast blow is plenty sufficient.
Quoted from johnboy1313:I got the new replacement rectifier board in the mail today and installed it tonight. Prior to installing it I was attemtping to fix a weak left flipper by adjusting the EOS switch and blew the 7a slowblow fuse on the rectifier board. Right before it blew I noticed the EOS switch itself was too hot to touch.
Sounds like the EOS switch might be wired wrong if it's getting hot and the solenoid fuse on the rectifier board is blowing. Post clear pictures of the wiring at both flippers.
