I?ve been down for many months now, tiring to finish up all those little things that have been bugging me about my Cub ever since I bought it.
One of the last items on the firewall forward part, are the mag wires (P-leads). As is typical with my jalopy, they?ve botched up this item too. I?ve been burned a couple times with the ?monkey see?monkey do? thing (read Teflon tape) so I need a quick lesson on the proper way to wire the P-leads. Note: I don?t have any filters, but there also doesn?t seem to be much interference, so I?m guessing that I don?t need any filters?
I?ve got the schematic for the system and it?s so simple that even I can follow it, but, I can?t find anything to direct me as to where to ?land? (place/attach) the final ground. I?m talking about the wire that goes from the ground stud on the switch to ????? Where are you supposed to ground the mags??
What is the proper gauge of wire?
Can somebody please explain to me why the P-leads, which are subjected to the most vibration that the aircraft can make, always consist of super small wires?
About the terminal connections at the studs on the mags. When I was disconnecting the right mag, I discovered that the nut had vibrated off and was laying in the terminal boot, the ring terminal was just barely hanging on the stud. The insulating washers don?t allow you torque the nuts very tight, so what trick are you doing to keep the nuts from vibrating off? Are these supposed to be all metal lock nuts? Doesn?t seem to be enough stud there.
