EM green horn here with a start sequence issue. Summary: sequence starts, score reels reset, no ball release, no playfield activity (besides gi).

History/work so far: game hasn't worked for 40 years. 0-9 unit had a melted coil and missing plunger - those have been replaced. Found a broken wire on the coin door for the replay button- fixed. New power cord, fuses checked. Tightened up the switch stack on the bank reset and score motor and inspected the movement of all the switches.

When pressing the replay button, the hold relay is working, the S and SS relays work, the score motor starts moving, score reels reset, the bank reset and the D relay activates, and the process stops. The ball release never energizes and there is no activity from the playfield.

I have schematics (that i struggle to understand) but at this point I'm a little lost and looking for tips.

Fred - thanks for the response. You also helped me fix heat wave about a year ago - that game wouldn't end. Bank a ball doesn't want to start

I checked that the primary switches all run the score motor (manually moved). I was still hung up on the fact that the playfield solenoids were "dead" so I recleaned the switches on the tilt, game over, start, and reset relay that have solenoid power through them. Each individual switch was making it, but on a whim I buzzed out the jumper wires between each relay and found a wire that was broken inside the insulation. Sneaky little bastard! New wire installed and she starts up and plays! On to the next issue

My best theory to explain the failure: the 0-9 unit coil overheated and blew the fuse. A previous owner over fused the circuit (I can't remember what was installed when I received the game, but it was higher than spec) and that caused the the bad coil to melt and the "new fuse" for solenoid power was the small jumper wire between relays. The two wires pictured above took some serious heat and both were replaced. When installed and the reset bank flipped up, the scorch marks couldn't be seen until the wires were removed. Sneaky sneaky.
