Molex is the scourge of a wiring system, they have no excuse for existing. Radio Shack featured them, what more can you say?

Default $400-$500

Molex / AMP connectors are kind of the GA standard. The problem is getting the correct crimpers which cost $400-$500. The $30 crimpers worked ok, but The single action, ratcheting crimpers that are specific to the gauge of wire/pin/plug made me laugh the first time I used them. There's nothing better.

I've seen bad Molex connections on components that cost $800,000 that were done with the wrong crimper in the part 135 realm. When I called the company and spoke with their DER about the bad crimps, he was unaware of the FAA requirement to use ratcheting crimpers designed for the specific connector.

The pictures in the first post are really sad - I wouldn't have that on my lawnmower.

Default Molex

I've used Molex connectors for some 30 years and never had a failure, but I solider every wire to the Molex pin after I crimp it. It's a pain but it works.

I don't see the original pictures (or any indication that there is a picture) with the chrome or the new edge browser. They show up in firefox.

To be VERY clear, these are sample photos of the type of connectors I'm referring to, not photos of my project!

Just curious what's the scope of your maintenance activities, a couple aircraft or hundreds? I do agree that if you take extra care with them it helps, but it's still a 2 cent connector prone to failure.
