    Well the number of factory crimped joints I have had fail on my Norge would suggest crimped joints are not so reliable.
    Though it's not always the cripm of the terminal on the wire, it's often the spade terminal fitting loosely.

    Yet I have a 1999 Toyota Tercel that has ( as pretty well every auto and motorcycle on earth has ) crimped
    terminals that are still fine , relays have failed and even a couple of batteries , but no electrical connections !
    Industry standards seem so variable . Certainly all the responses here seem to verify that . Does anyone else here think
    a registry dedicated to specific failures (electrical) would give us a heads up on what to check and possibly
    replace before failure occurs might be an idea to pursue ? Peter

    Peter, crimped connections work fine until they don't. Crimp connector is by physical contact which may in some cases be sufficient for good conduction. When you don't have good conduction (resistance) you get heat build up. With a solder connection you have good conduction and thus you don't get the heat build up. In the case we are seeing here, heat was generated most likely from poor conduction. Soldering the new connections will prevent that happening again. In many places I will use a crimped connection, but where necessary the soldering iron comes out.

    LaGrasta -- I concur with JZ's recommendation -- individual connector for each wire, soldered and adhesive shrink-wrapped. I also recommend Honda's 08798-9001 grease for oxide protection and moisture blockage but this is controversial.

    Connectors: https://www.amazon.com/gp/product/B07FCFH84Q
    Heat shrink: https://www.amazon.com/gp/product/B06XDYQ4ZT

    Due to the heat damage you will probably have to cut the original wires back an inch or two to find un-oxidized copper so extending them will be necessary. I suggest replacing wires on both sides of the regulator. Use #14AWG stranded -- solder and heat-shrink. For the connectors use the 6.3mm (0.25in) size -- sockets on the alternator and battery ends; plugs on regulator ends. Use color-coded heat shrink to distinguish functions: alternator windings (Yellow), battery positive (Red) and battery negative (Black). Crimp the connectors on the wires; solder; and heat shrink -- covering the solder joint and extending at least 0.25in past the connector. Having the proper crimping tool, soldering station and heat gun is very helpful.

    Soldering the wire to the connector provides two benefits: oxidation protection and mechanical strength. But without a soldering station it can get messy. The adhesive heat shrink provides both those benefits to a lesser extent but should be good enough for a few years of riding.

    WRT KD's trinity, a punch block provides a sealed welded connection; a wire wrap provides a welded connection; and a soldered connection provides neither. Soldered connections also have a failure mode due to the solder traveling past the connector into the wire strands where it is susceptible to vibration breakage. My solution is ... you guessed it ... an extended length (0.5") of adhesive heat shrink. But I only do this for a friend's SCTA roadster, not my MG.

    One preventative step I would always suggest is to spray every connector you can find with some electrical contact cleaner and lubricant. Stop moisture getting in and causing corrosion.

    The main problem with crimped connections is they need to be properly crimped (including proper stripping of the wire) and properly seated in the connector. Then then most need routing for stress relief and tied down to maintain a stress free position.

    I didn't work on rockets but I have wired entire aircraft from nose to tail. Crimp connecters work fine but they need to be installed properly and precisely.

    Something to consider. If the aircraft has a problem, you don't take off. If you have a problem the missile better work!!

    Guess it depends on where the missile is pointed?

    This is almost as exciting as an oil thread. ;)

    Solder, crimp, or spade?

    And no one’s even weighed in with strong views on Posi-locks and Posi-taps! :giggle:

    It's bordering on painful . No one's brought up how every house in North America uses Marretts connectors
    for their houses :) . Kinda like a crimp connector with a twist ( Get it :D:D:D) Peter

    Not quite, if you ask 50 people about oil you usually get at leat 70 different answers.
