In the middle of a game it just went dead, no lights, flippers, or anything.
All fuses verified with a multimeter, all the correct voltages coming out the transformer. I replaced the fuse holder and the lock coil, verified continuity of the switches on the lock and game over relay but still dead
If I manually trigger the lock relay it lights up again but it looks like it is still on the game it was playing when it died. I'm a little stumped
Quoted from currieddog:Check all the Tilt switches?
I may have but I'll check em again.
I pulled out the playfied and it still does it
Quoted from HowardR:At the risk of asking an obvious question, what does it do if you press the Replay button?
And I don't know what symptom you're diagnosing.
I was playing a game and for no apparent reason it turned off like it was unplugged and stayed like that. The only way to get it to show any signs of life is to manually push the lock relay and then the head and playfied lights up like it was still in the middle of the game it died during. Pressing the replay button does nothing when it's dark or when I'm holding in the lock relay
Quoted from HowardR:Does pressing the Left Flipper button activate the Lock relay?
When you push the Lock relay, does it stay activated?
No to both
HowardR for the win again
Jumped B-Y-W and - Black- at the 15a fuse and it came back to life. Weird part is its a new fuse holder and new fuse that tested good out of circuit
It resets and plays mostly fine, occasionally the score motor makes an extra rotation during reset, and, the captive ball kickers don't work. When the ball goes in the space I can hear the score motor running continuously but it doesn't kick the ball out
Quoted from Action53:When the ball goes in the space
What does this mean?
Quoted from Action53:The to spots I scribbled yellow

Simple circuit to troubleshoot assuming both "shooter" coils are good ( they really never go bad) and the wiring to them, including the common wire to them is intact:
There is a "Shooter" relay. Find it and make sure the contacts on the switch with the Blue=Red wire are clean and adjusted properly. On the score motor, Cam 4 (5th Cam away from the motor itself) the switch at the bottom of the stack needs to be verified as clean and properly adjusted to make when the cam is rotated and at the high spot during a motor cycle.
Only other possibility is a corroded or not fully inserted Jones Plug between the Playfield and bottom board or broken wire. Best chance for a broken wire is the Jones Plug or the common Shooter coil feed which I recall comes off of a Flipper Coil.
