Firepower right flipper switches sit close to the pawl: a short kills the switch matrix
On Firepower the right flipper has two cabinet switches side by side: one carries flipper coil voltage and the other is a low-voltage switch matrix input for lane change. Both sit very close to the metal flipper pawl. If both touch the pawl at once (for example while working on them with the power on), coil voltage goes into the switch matrix and can blow several chips on the board, killing the switches. Never adjust these switches with the game on, and keep them well clear of the pawl.
Switch the game off before adjusting any switch.
