The mystery hole scores as the coffin ramp and the coffin ramp scores as the mystery; switch test confirms the two switches are reported the wrong way round.

Mystery hole and coffin ramp score each other: two under-playfield connectors swapped

Cause: Two connectors under the playfield had been plugged into each other's mates. Their wire colours matched, so the swap was easy to miss.

Checks

• Check the switches in the same rows and columns work, to rule out a matrix fault.
• Compare the wire colours on both halves of each under-playfield connector near these switches, including any position with a doubled wire.
• If possible compare against another game of the same title.

Fix

• Swap the two connectors back to their correct mates and recheck in switch test.
