The right flipper has no power at the coil; power is present at its fuse and at the power board connector but not on the far side of the interconnect board.

Right flipper dead after a coil cooked: burnt trace on the interconnect board

Cause: A badly adjusted EOS had let the flipper coil overheat; the overload burned a trace on the interconnect board and the coil.

Checks

• With connectors unplugged (so you don't read through other coils), check continuity across the interconnect board from input pin to output pin for that flipper.
• Look at the back of the board for a burnt trace.

Fix

• Repair the trace with wire, replace the cooked coil, and adjust the EOS properly.
