Default Automotive Electrical Connectors

Friday was our Plane Day this week. We got some major electrical behind us,,,however when we powered up the board and tried to retract the Jack Wihelmson nose lift,,,,,NOTHING!! What has been working fine for us for years since initial installation was now doing anything! After about two hours of tracing and testing,,,,Thane located the problem(s). The first was the electrical connection Jack made on the assembly. The crimp on the blue auto splice connector he used was ever so loose and power was not going thru unless you wiggled it. The second problem was the second auto splice connector which was doing the very same thing!! Both were replaced with a soldered splice and shrink wrapped. I know the subject was recently discussed,,,so a lesson was learned first hand is to keep away from them. Overall, it was a very productive day with many loose ends cleaned up!

Those butt splices are an accident waiting to happen.

I'd advise STRONGLY for everyone to not use those.

Not only is there no stress relief, but I've never seen anyone use the correct tool to get a gas tight crimp.

Oh gawd those butt splices look awful. I have the right crimper for them, and use it, but man, doing it without the $150 tool is asking for disaster. Literally.

Solder and heatshrink and real live connectors and proper crimp tools are your friends (but not all at the same time). Anything else is a mistake.
This is not a sig. This is a duck. Quack.
