Quoted from JustLikeMe:
Hoping someone may be able to help me with an issue I just encountered. I switched the game on for the first time in a few weeks and got an error - I think it was something along the lines of Black Pearl access ramp switch stuck open or similar. I didn't pay much attention, thinking I'd just play a quick game in the hope that it was just a switch I hadn't activated in a little while.
I started the game and everything was going fine until I started a few multiballs and stacked in arrr frenzy. Suddenly the machine went crazy, constantly awarding me arrr frenzy points as if I was ripping a spinner at speed - and it didn't stop for the whole of the mode. I went from around 150,000 to just over 24,500,000 in less than a minute. As I clearly couldn't attribute that to skill I drained the ball and entered the service menu to end the game so I didn't end up with an undeserved GC score, but when I went to look at the switch tests nothing unusual was showing up.
I restarted the machine hoping I'd get the original error back so I could investigate properly, but nothing showed up - when there's clearly a problem somewhere. I'm annoyed I didn't take a photo of the switch error, but I figured it would either clear or still remain after the game. Can anyone point me in the right direction here?
Ok, I managed to work out what was going on last night thanks to eaglepin and zora, and thought I’d post here just in case anyone else has a similar problem in the future.
I started a game and all was fine until I started a couple of multiballs together, at which point my score started increasing rapidly again. As suggested I quickly went into the service menu to have a look at the switch history, which made the problem pretty obvious:
Out of curiosity I restarted the game which caused the error to return on startup:
Checked the manual and worked out this was the opto pair at the top of the Black Pearl access ramp - had a look and the transmitter on the left had come away from the ramp and was hanging by its wires. Obvious from a side angle but invisible from the player position. Clicked it back in and everything is working perfectly again.
