Quoted from iluvak9:Pretty sure it was caused by replacing a bad coil with a brand new replacement coil that turned out to be bad as well.
History: Game was working fine and then GAR drops stopped resetting. Fixed a lose wire in target assembly. All good. Then, a few days later had fluttering right flipper. Could see coil wires in middle lug had separated from lug and so I ordered two new replacement coils. Switched bad coil to one of the new ones and game was working again. A day or two later I encountered the issue with the right flipper causing “Gorgar” to be spoken each time I released the flipper button. Spent way too much time diagnosing the target assemblies, boards, and looking for possible spilled solder on the wires. Finally, I thought could this be a problem with the brand new coil as I was desperate. Switched to the other new flipper coil and now game is working again. Two days later, and still working, but I am not yet past the “nervous” stage.
Do you remember which wire was loose? I'm having an issue where the Gar targets aren't resetting when I start a game and they do not reset when I manually raise and then trigger each to go down. Score works, its just the coil is not firing. I replaced the coil, but still same issue. I saw this post and thought maybe I'm encountering the same thing. I did blow a fuse recently because I hooked up the old coil wrong against the diode, but with the fuse replaced all the solenoids seem to fire except this one...Gor drops seem to work fine...
