 |
|
Hey guys,
I'm currently un-mounting a Rotax 912 ULS from my Kitfox. I noticed a couple of annoyances in the process of unconnecting everything ...
The magneto wires on my Kitfox feature a braided coaxial shield. I'm not too enthused about the way these were handled by the original builder. The shield is basically bunched together and soldered to a ground wire. One of the solder joints was hanging on literally by a thread .. so what do you guys recommend for tying the braided magneto shield to a ground wire? I'm considering bunching the braid together, applying a dab of solder, then butt splicing to the ground wire.
Also, my Ducati regulator plug has wires leading both to the engine and the instrument panel. It looks like each wire inserted into the plug is terminated in a female spade lug. However, they can't be pulled back out of the plug .. I'm guessing there is a plastic locking tab somewhere. Anybody know how to yank wires out of the Ducati regular plug?
While we're on the subject .. does anybody have advice for unmounting an engine for the first time? Things to avoid, etc? Thanks!!
Carl

Hah that's pretty clever! Thanks for the tip.
Anybody know how to yank lugged wires out of one of those black Ducati regulator plugs?

Never use solder on any joint that has to endure vibration. The solder
wicks up into the strands of the wire and causes metal fatigue where the
wicking ends. That is what happened on your present wiring.
Places where you can expect vibration (read airplane, car , motorcycle...
Etc..) should be connected using decent crimped on connectors.
