Changing flipper coils, diode direction?

[AE35]

Hi all

I'm thinking about changing the flipper mechs in my Xenon, to get rid of
the linear mechs and installing a pair of System 11 I have lying around.

However, both coils seem to be parallel but have their diodes pointing
in different directions. Should I reverse the diodes on the System 11 mech
coil? I've attached two pictures of the coils. It didn't escape my attention that
new coil strength might be too much

Thanks!

If I remember, the banded side of the diode should be installed towards the power wire.

I copied this from the TOP repair guide hoping it might help:

----------------------------
When Replacing a Coil Diode...
Remember to always install a coil diode with the banded end of the diode to the power wire coil lug! The power lug is the the one with the thicker red or purple wire connected to it. This is usually the lug with TWO wires connected to it (because the power wires "daisy chain" from coil to coil). If you install a diode in reverse, it will instantly short and be ruined when power is applied.

Diodes Mounted on the Coil...
Sometimes a diode lead breaks on the coil from vibration. When replacing a coil, the repair person can install the coil wires incorrectly (the power wire should always be attached to the coil's lug with the banded side of the diode). To prevent this, Williams moved the coil diodes off the coils and onto the Auxiliary power driver board starting with Big Guns. This isolates the coil diode from vibration and eliminates the possibility of installing the coil's wires in reverse. This was done on most coils except the flipper coils.

One of your coils must not be correct... which would make one of them weaker... which would make you suspect the crappy linear flippers

The flipper coils have two sets of windings, that connect to the three lugs. Unless the coil was somehow wired backwards than how it's traditionally done, it's hooked up wrong which would make 1 of the windings likely not even work and the coil be weak. Even if you swapped the wires to where they should go you'd have to swap the diodes too.
