I've been working on a Space Invaders pinball, bringing it back from the dead. I was almost finished with it, when the left upper flipper (smaller one) stopped working. The larger left lower flipper still works.
I cannot find any copies of that great repair document that used to be on the web.
So any ideas on where to start? The coil is a three lug style with a diode. How do I test to see if the coil is good or not? I should mention that I have a new Alltek solonoid board in the game.
One more question... what size are the small connectors on the main board? I mean they're small! I reseated those and the game will no longer start a game unless I move some wires on one of those darn connectors. It also has a Alltek MPU replacement, so I'm sure it's not a cracked solder joint, just an old connector plugged into it.
Thanks
Tom
