AHA! you weren't talking about an alternator filter . . .
but an ignition module filter . . . I'll learn how
to read one of these days!

Greetings from the right 'rabbit hole' . . .
Okay, I peeked at the mounting bracket and the 36D
series capacitors and ran down the wrong rabbit hole.
I don't recall the source data for LOM magneto
wiring . . . Z18 was crafted many moons ago! However,
I'm pretty sure we're working with legacy magnetos.
Therefore, those filters would be of the type
recommended for magneto p-leads. These are generally
a series inductor paired with a shunt capacitor.
Try flying with no filters. These were generally
needed only for low frequency AM radios. I'm
presuming you won't have these installed!
Wire the mag switches as shown . . . ground the
switches through the p-lead shields with no
other connections to ground at the switches.
I think you have a good chance of experiencing
no magneto interference.
If you DO notice some on your VHF comm radios,
we can craft some filters to try. They're
not complicated. But to be sure, fat
electrolytic capacitors are not part of
the solution!
