Pictures are super helpful, thanks! Not stupid at all haha. But, I actually did already try with the 4 balls, no luck. I'm going to attach a few more pictures here that will hopefully help. Basically:
I have the four balls aligned like your machine. As soon as I hit the power, the right solenoid engages and never releases after that. I'm working under the assumption right now that it's some sort of grounding issue since I just sent the driver in to be serviced (he said it was tested fully and no mention of a replaced transistor. Hopefully that's good unless I somehow blew it again). First picture down below is machine completely off (lane is open...solenoid disengaged....second picture is as soon as I hit the power....solenoid engages...closes the lane...never opens again)
Also, as you can see in the pictures, previous owner (actually previous, previous owner...guy I got it from picked it up as a project and it came with me as a project) did a ton of upgrades but also what makes this so tough to diagnose. Weirdly, found the wire on this solenoid was cut by the last guy...I reconnected them and immediately had this issue...so I'm thinking whatever problem I'm having right now is a problem the previous guy had too and his solution was to just disconnect the solenoid.
Also, cabinet ground mods have been done, but assuming the backbox mods haven't because a majority of the connectors have new molex?
Do you think doing the ground mods would help here? (Also, I'd have to email Swemmer to figure out where the best place to ground to these new boards is)
A side note that I'm also noticing - the GI is working on startup but goes out (and never comes back on) either when I start a new game (which looks like the GI is supposed to go off until you plunge the ball from gameplay videos online) .....or also goes out when in attract mode as soon as soon as the flashers go on for the first time (as soon as the flashers go on...kills the GI)
Again...thinking some sort of grounding?
