Solderless connectors (crimp) or solder connections for electrical repairs?

[Scot Minesinger]

Working on a 1970 troubled Cadillac that ran the battery dead in a few hours.  The former owner cured it with a battery disconnect in the glove box.  The #2 cables intercepted negative battery to ground and switched it off every time the car was not running.  I don't work like that.  There were about 100 crimp connections under the carpet.  I replaced them all with proper wiring harness and the battery lasts (has not died yet).  So not a fan of crimped connectors unless they are done correctly.

That’s a typo. It’s not “sodder”. It’s solder.   

I was referring to the way it sounds when people talk about soldering on the TV shows.

as i am a railway signal electrician i believe that a properly crimped lug is the best. our australian standards do not allow soldered joints . we have to supply a sample crimp for every 50 lugs we do these are then subjected to a pull test to breaking point and the breaking strain measured. our work is safety critical so quality is an utmost. this is what we use https://www.tradesparky.com/tools-and-workwear/hand-tools-and-blades/cable-tools/cembre-hp3-ratchet-crimping-tool

And we cannot forget the accents.

Bloody well right (from Supertramp)


I use both types of connections and have not had any issues with either method.

I just bought some of these. They solder and heat shrink at the same time. I haven't used any yet except to test and was not able to pull apart.

That looks like what we used for shielded leads.  The shield is there to reducer RF noise.  The solder ring solders the shield and the hot melt glue rings glued the outer covering at one side and the leads on the other.

Plus, be good for waterproofing joints.

Maybe it was 1989 or 1990. We, as GM DSMs, we had a 5 week technical  training in the USA. To repair wiring for the air bags, the instructor showed us similar "connectors" which had to be waterproof.
