Yakers,
I may be opening pandora's box here, sorry Dennis, but the Auto-spark plug conversion kit that Bill Blackwell and all the DVT guys are using has a very cool machined part with individual holes for each plug wire where they enter the mag. Each plug wire then has a tight seal as it goes through this block prior to entering the mag. This eliminates the possibility of water entering the ignition system at that point.
I lost a good friend years ago flying a Beech 18 after he had a dual engine failure flying through a heavy rain storm. The NTSB found that water entered the ignition systems of both engines and forced him down. I was supposed to be on that flight...after that, my CFI-Dad told me no more flying night cargo...

Jeff,
Bill Blackwell's conversion is also an excellent conversion. If you take a close look at the original Russian harness paying particular attention to the braided shielding that surrounds the mass of plug wires exiting the magneto and also the braided shields on each individual plug lead, you will note the braids are porous. Moisture can surely penetrate these braids. (Spray silicone spray on the braided shields when you have a misfire). If you look at the 90 degree elbow end of the Russian wiring harness where it connects to the spark plug, you will see a rubber hose abutting up against the 90 degree elbow. There is no seal between the rubber hose and the end of the 90 degree elbow. That rubber hose covers the braided shield on each spark plug lead and also helps protect the lead from chafing when passing through the engine baffling. During a driving rain storm, moisture can easily find its way under that rubber hose on the front spark plug leads and penetrate the pores of the braided shield. Try washing down your engine with a water bases solution and you'll find out if moisture can penetrate the braided shields or not. If you look at my conversion kit plug ends, the security of the fitting over the spark plug virtually eliminates any possibility of moisture penetration. Finally, when you look at the magneto cap end where each wire enters into the magneto cap, it is no less susceptible to moisture penetration with the Russian wiring harness than with the automotive plug conversion kit I sell. If there is concern as to whether moisture can enter the magneto cap through the tightly packed 8 mm wires, RTV/silicone sealant around the opening and in between the wires will remove that concern and any potential moisture penetration.
Either conversion, Bill Blackwell's or mine, removes the "Achilles heel" of the M14, which is the Russian wiring harness and significantly reduces operating costs for the long term.

Dennis I can confirm that experiment, I was draining moisture out of the lower plug shrouds for weeks.
