Well I still don’t have a pinwiki account but here’s my list of problems and solutions for POTC so far. I will replicate it there once I am approved.
Problem: Chest seems to reject shots that it should have captured.
Solution: Remove the chest mech from under the playfield (5 screws.). Tighten the two screws for the fork which are likely loose. This is a common problem.
Problem: Balls getting stuck at the top of the Black Pearl ramp.
Solution: Ensure the game is horizontally level, measured at the playfield. Next, locate the screw to the right of the ramp which compresses a rubber crush washer. Tighten this screw clockwise until setting balls on the top of the ramp always makes them roll away right. This fixed the problem for me permanently.
Problem: The Black Pearl rocking motion sometimes halts (especially during the cannon shot) or otherwise seems to struggle in the calibration test.
Solution: Put the playfield in the first service position, such that you can observe the motion of the arm. Run the ship calibration test. If the pin that controls the rocking of the Pearl contacts the top or bottom of the slot, loosen the two screws on the control arm and correct the height travel is unimpeded in both directions. This took a bit for me to find, but after correcting it the calibration was able to run all the way down to 4, and the ship rocking was much more playable.
Problem: The metal rails in the shooter lane are malformed, causing bad plunges
Solution: Take pictures of the shooter lane before removal, noting the angle of attack into the right orbit. Remove the shooter lane. It has 3 connection points, one hex screw near the top, the “stack” which holds the right strobe, and a small black screw near the bottom. With the wireform removed, gently bend the bottom two forks such that they are slightly down and slightly apart. The goal here is to make them hug the shooter lane when reinserted. When reassembling, take care not to strip the black screw. I was advised to put the screw in and gently turn counterclockwise until it rises up, to ensure it hit the threads correctly on reinsertion. This fixed the problems with the shooter completely.
Problem: Maelstrom exit ramp switch reporting stuck closed
Solution: This may be more of a “general pinall troubleshooting” thing. I removed the switch and found the plastic plunger in the microswitch was stuck down. Loosening one of the set screws on the switch itself freed it and normal operation resumed.
Problem: Game reports switch errors on the ship on startup
Solution: This is a normal condition that happens if the ship hasn’t been hit in the last N games and usually does not indicate an actual fault.
Problem: Game reports stuck MAP targets
Solution: In my case the targets were mounted too closely together and were physically stuck behind one another. Loosening from under the playfield and moving them apart resolved the problem.
Problem: Game reports stuck GOLD targets
Solution: In my case the L target was getting caught under the wiring harness on the Pearl ramp. I loosened the target and pressed the harness up and out of the way, then reinstalled. The Pearl ramp adjustment to stop the ball from sticking on the ramp also helped.
Problem: Chapter Select or Left Orbit posts fail to raise up
Solution: Locate the posts under the playfield. Adjust the position with the screw and lock into place with the hex nut.
Problem: Action button sticking during gameplay
Solution: Remove the lockbar. Depress the action button and apply a small amount of lubricant to the exposed plunger. I had success with WD40, others used silicon spray. Clean off any excess before replacing the lockbar.
