DrDave. Excellent information.

Lately I've been pursuing an issue with the P lead magneto filters.

Sure enough, there's not one to be found on the plane. Looking at the wiring diagram (page 18-27 in service manual) for the ignition system its either a filter is needed for each mag or shielded 18 gauge wire per note #5. The plane has neither...just plain 20 gauge coming off the P lead. I'm crossing my fingers this is the smoking gun. Mag filters to be ordered.
The Bendix mag filters seem pretty vanilla to me, any recommendations appreciated.

Cessna is also very specific about adding shrink tubing to the ends of the connecter to the mag filter...again...I'm hoping the little details matter.

btw: Mags are fresh out of OH, probably 50 hours. I had a 'Leroy' tell me mag filters not needed if the mags are fresh/fault free....is there any truth to this? I countered that Cessna put filters in the parts manual for a reason...
