Ignition 'noises' will not be materially affected by breaking the p-leads with a connector . . . but it DOES introduce risk of discontinuity by reason of 6 new joints added to the magneto control system. Joints that add very low if any utility to maintenance of the airplane. The amount of wire from firewall to rear of mags approaches trivial . . . easily managed during engine remove/replace operations. Bob . . .

I just don't like to mess with cables that are beautifully routed and properly supported. Since my Rotax ignition system is designed that way by the factory (and I really like that!), I was considering that option. But you are right, it will affect the reliability of the system. It may not be a problem on the Rotax because it will not start if turned by hand with the ignition not grounded, but it may be risky on a conventional Magneto engine. Thank you for the advice!

Fabricio, Do use Bob's suggestion about using a solid connection. An added detail is wire it knowing that engine "Shake" is hard on the connection especially it you have used too short of a P-lead harness. Leave it long enough to secure well but tolerate engine movement during start and stop periods. The extra length will allow you to repair the P-lead in case future vibration breaks the lead at the mag. D On Fri, Apr 8, 2022 at 8:53 AM Robert L.

Nuckolls, III" Subject: AeroElectric-List: Wire stripper deal . . . Was in Harbor Freight yesterday and spotted an el cheapo wire stripper that was interesting. This QUINN product uses a solid rivet in the pivot point and a handier travel stop to set wire gage. Bought one and hauled it home. Does a really nice job and with the solid shaft, more likely to stay tight with age/use. The el-Cheeso design has been around for decades and I have a few of them . . . which I'm going to pitch and replace. The $5 HF offer is about 1/2 that of offers on eBay, et. als. Bob . . .
