Looking at the top of the (Slick) magneto I removed the nut and star washer and found an insulating fiber washer. Looking under the washer, there is the threaded stud which projects from a piece of white plastic that is in turn surrounded by a shiny piece of metal that looks like a large nut. My question has to do with grounding the P lead out on magneto which is what lectric Bob recommends for lowest system noise. I assume that the fiber washer is there to keep the P lead terminal from grounding the threaded stud to the "shiny metal nut" that surrounds the plastic that the stud projects out of. If so, can I use two ring terminals on the coax, one with a much larger ring placed under the fiber washer which will serve as the return grounding path and then place a smaller ring terminal (connected to the other wire in the coax)on top of the fiber washer (which is on top of the larger ring terminal contacting the shiny metal nut) under the nut that goes on the stud and not have to worry about magneto grounding somewhere else on the engine? I'm just trying to not have to strip a whole bunch of shield off the P lead for grounding at a separate location and this looks like it should work but I know nothing about magnetos so I'm not sure if my hypothesis is correct. I hope you can decipher what I trying to say. Thanks. Dean Psiropoulos RV-6A N197DM Stringing wire (still)
