Quoted from tpike:I don't get how the switch matrix works. I don't know how that relates to the wire schematic.
This should help you get started in understanding the switch matrix.

Unlikely it's a transformer issue. Could be a high resistance in the circuit, which will draw too much current. Check all of the grounds and make sure they're clean and tight. Check everything on the left flipper supply and control lines.
If you still have the head out I would replace the part that was super glued. That type of adhesive really doesn't like vibration and will likely not last long. If the part is not available and you must glue it, there are much better choices than any of the super glue versions.
Quoted from Jkush18:Total noob here please elaborate
Page 3-11 and 3-12 in the manual. Check the +50 volt wire going to the three flippers. Check the switched circuit (labeled power, not hold) from each coil to the fliptronics board. Check for loose or frayed connections. Remove J902 and J907 and check the male pins for corrosion.
This could also be a soft 50 volt supply to the coils since 3 coils are on the left side. Check the 50 volts going to the left coils with a meter.
