Picked up a Gorgar last night, brought it home & all was well - played over a dozen games on it. All of a sudden the start button & flippers went dead & did nothing when depressed. Went into the adjustment menu & reset #18 to free-play, that worked, we can now start a new game with the start button; however, flippers are still dead. Ran diagnostics, all the solenoids fire as they should. While I couldn't find/get the 'switch test' to activate in the diagnostic mode, I did start a game and depressed each rollover/switch/target by hand and all work fine (except flippers). So, the ONLY issue at the moment seems to be that the flippers are not doing anything.

Leaf switches all look fine, open/close when manipulated manually. Coils don’t look burnt or anything - ideas?

No difference following reseating/tapping

Reseated 40-pin, no go.

F4 is not reading good, so I suspect this is the issue - unfortunately I don't have one lying around & our radio shack has gone out of business so I’ve ordered some that should be here Monday - will post back after. Should F4 be affecting anything else, as it seems everything else is working?

Did a quick online search, auto parts store had 10A, but not SB

Fuse fixed it, go figure/thank goodness. Appreciate the help!
