Trying to get a Bally mystic gate running but my EM troubleshooting knowledge is t the best.
It was working at a 2019 show, then was stored in a climate controlled area for two years, now setting it back up.
Took care of everything obvious I could find, all steampunk octopus units (relays?) seem to be functioning correctly, they all step forward and reset when the respective coils fire. A few playfield switches we're stuck and I took care of those. replaced the old fuse holder block, and a wire or two that had popped loose.
When I turn the game on, lights come on, backglass lights are as pictured, the coin unit (middle of rear door on the far left) advance coil is locked on. It pulsed a bunch of times first then stuck on. I had repaired a loose wire on that before hand.
I disconnected the coin door switches thinking there might be a coin switch short but it didn't matter.
I've never been great at getting these running though I can usually troubleshoot once they show signs of life.
