The legs of the relay driver transistor responsible for flipper enable were pushed together. Probably from when board was laid down to reflow solder. Separated legs and works as expected now.

Closed Problem: Flippers are on even when game is over. The flipper ground relay is for some reason now active even without a game running. Since I recently reflowed its output pins, it's worth checking those first.

Closed problem report

Closed Problem: Rubber Pad should be replaced. Worn down, metal exposed. Ideal temporary fix: Rotate the Pad 180⁰ Problem: The arm would not budge from the rod. I did not want to force it Plan B Temp Fix: Electric Tape was added to prevent exposed metal

Closed Problem: Pressing the left flipper causes the machine to say “mission completed”, doesn’t award points 🧐

Closed problem report

Closed Problem: Upon completion of flipper rebuild i hit the right flipper and it got “stuck” drawing high power. Subsequently, flipper died. Im pretty sure the continuous high power draw to the solenoid shorted something upstream, but i didnt have time to investigate thoroughly. One additional note, i desoldered some wires on the solenoid on the flipper assembly switch stack. Im confident I resoldered them in the right positions, but it was getting to the end of the day. Attached are pictures of the wiring before i unhooked any of it.

I realized that the soft coil problem was because the EOS switch wasn’t right. I cleaned and regapped the switch and everything started working. I properly mounted the new coil, resoldered the wires, and adjusted the flippers. Everything played properly, except that the flippers are active even when the game is over.

Desoldered coil to check resistance. Was a little low. Jumped to other flipper and it worked fine. Incoming voltage on blue wire is fine. Incoming ground on blue-violet showed no connection, as does orange-violet to right flipper. Traced problem to 2J12 pin 1. Reflowed solder on pin to create reliable connection from relay.

After putting the board back, the right flipper would twitch but not work fully. I tried swapping in a new coil and discovered that the flipper had been installed too tight to the playfield. Loosened that.

Currently the right flipper twitches. I tried a variety of jumper wire combinations and I can’t isolate the problem with the left flipper. Maybe the next step is current measurements?

Locked power off in Juice to prevent accidentally blowing the fuse again. Next step is to compare left and right power wiring and coil resistance to find why the left flipper is blowing fuses.
