Regarding terminal crimping:

 

I gave up on crimped terminals decades ago, and now any wiring I do on anything mobile get soldered.

 

Yeah, I know that every factory terminal is just crimped and they have been doing it that way for 100 years. I just don't seem to get a good crimp 100% of the time, and I can solder 100%. Maybe it's the quality of the crimper, or the precision of the terminal or the exact position of the wire, but they just don't seem really secure to me.

 

Anyhow, crimped terminals can vibrate loose, corrode easily & they look cheap, and frankly I just like to solder.

In the early part of my career I spend a little time in a factory that was building things for the military and nearly all connections were crimped. But the crimpers were not the type you'd buy at your local store as they had dies for exactly the connector they were to be used with and they were sent off for adjustment/calibration on a regular schedule to assure the crimping force was correct, the dies weren't worn or miss adjusted, etc. I suspect the auto industry is using specialty tooling and keeping it calibrated just as we did way back when.

 

On the other hand, a bunch of the electrical problems I had with my '82 Plymouth when it was a few years old were due to bad crimps on the big bulkhead connector that took most of the wires in and out of the passenger compartment. So they weren't always doing a great job on crimping.

 

For myself, I use a cheap hand crimper to get the terminal to stay on the wire just long enough to solder it. And I try to make sure that the solder does not wick up the strands of the wire which could stiffen it and make it susceptible to a fatigue failure.

Yes, I'm afraid that neither my Cal-Term crimper, my K-D crimper, nor my Globe Tools crimper were ever calibrated to anything at all, ever.

 

I never did much professional electrical work, but we made a lot of double flares and crimped a lot of hydraulic hose fittings at Manlift Inc, and those dies were checked and replaced routinely.

 

My '69 Evinrude outboard has one of those big multi-pin rubber plugs for the whole harness, and I went through that thing from both sides, one wire at a time, de-crimping and soldering on new wires. What a PITA that was.

Here is an interesting tune up package that includes the pesky little wire . The wire in the photo is actually a used one as you can see that the insulation is starting to fray on one end . Since the wire is included in this package , i am thinking that it must have been common procedure to replace the wire . I bought this package on ebay a couple of years ago and it may not be available anywhere . P1010191.JPGP1010192.JPGP1010193.JPG

 I recently found four of these packages , a woman had them in her unlighted barn . A true barn find . So there might be more out there .
