    What brand is good? And who stocks em?

    Sick of shitty terminals falling apart as you sqeeze them up. Have taken to putting shrink wrap on the wire to slide up onto the terminal connection to cover where the shitty blue or red plastic breaks apart.

    I always solder the wire ends before crimping them and have got good quality tools to do the crimping.

    Input appreciated.

    Try bursons, they have smaller connectors that fit into blocks. I have these and covers I got from an online parts supplier. "Z1 enterprises"

    you dont normaly solder the crimp type ,if you need to i normaly crimp then cut the plastic shielding off, a lot of the crimp does depend on tool i use the double crimp wurth locking type proffesinal ones , as far as terminals ,narva, alanco, wurth ,evan the supercheap ones work for me but even than you still get the odd dud one .

     G'day Burnzi, I work with these thing every other day, so this may bore you a bit, but it's with the best intentions.  While soldering all connections gives the best contact, its very time consuming and not practical thats why the red/blue/yellow crimp lugs are convenient. but they're not designed to have the wire soldered first and then crimped. Sometimes they will fall off because the terminal end you crimp cant squash in enough and provide enough compression to grip the wire. Crimp lugs rely on gripping and squashing the smaller bare copper wire to work effectively. I also twist the bare end first before crimping as this makes it harder to pull the joint apart. ( I liken it to decking nails).

    We use both wurth and narva brand crimp lugs and toledo and cabac crimping pliers. Never usually have any dramas apart from the occasional defective one.  any way thats my  $2 wurth. Ha ha. See blackwoods or wurth reps to buy from.

    Hope this helps.

    Part of the problem with soldering on a potentially vibrating/moving wire is the solder heat, depending on the wire gauge, may affect the heat affected zone just right behind the solder.

    If vibes are present they might work harden the wire and come apart behind the soldered connection. Having sad that heat shrink should help keep the wire rigid and vibe free provided it was a straight and not a bent or curved connection.

    I'd go with FLHuTChUu on this. Quality crimps only, no solder. JM2C <img src=" align="absMiddle" border="0" src="/DesktopModules/NTForums/themes/_default/emoticons/smile.gif" />
