I have a POTC that I have been working on. I put LEDs in the machine way back when I bought it. This must be ten years ago. I was having a lot of ghosting issues with the original LEDs so I went through the single lamp test to replace the problematic bulbs. I cannot find lamp 47 Tortuga. The manual has it listed in the wiring diagram but there is no actual playfield location. Oddly enough there is a cut out on just behind the Tortuga-Port Royal ramp and there is nothing in it. Can anyone tell me where this missing lamp (#47 Tortuga) should be?
