I took out the playfield from my Sorcerer to install new leg brackets. After the job was done, I put the playfield back in, checked all connections and turned on the game. The game now shows error code 7 and the right flipper is locked on. I'm not sure what happened, as it's a pretty straight forward job to disconnect and remove the playfield, then reinstall the playfield and reconnect.
I'm not the greatest schematic reader. Am I correct in suspecting Relay Z1 is bad (closed?) but if that were the case, wouldn't both flippers be locked on?
I did check the lugs and wiring on the right coil and they looked ok. On the left coil, it looks like the diode was replaced at one point since the leads were long. I did see that (maybe during the move) that a lead on the diode might have been touching the center lug on the coil. I moved it out of the way. I haven't checked to cabinet switches yet to see if I might have bent the switch tabs and now they're touching, but I'll do that when I get a chance. What is 8L24 on the schematic and could that be the culprit? What are your thoughts? Could it be as simple as replacing the diode on the right flipper?
The other issue I'm coming up with is Error code 7. I've seen this come up before and the steps I took were to reflow solder on the header pins, and re-seat the game ROMs. I played a couple dozen games since then with no issue, and now it's appearing again. Do you think the two problems are related?
