Long story short, I need to splice some wires together for an adapter harness for my car's head unit. I am also terrible at soldering. I see McMaster carries "Sure-Connect Sealed Butt Splices", which look to be a butt connector that you crimp on, then heat to simultaneously melt some enclosed solder and melt the heat shrink. Is this something that I would want to use?

Just get a cheap pair of ratcheting crimpers and a box of blue butt connectors.

Personally, I'm terrible at crimp-on butt splices. These are my favorite: http://www.mcmaster.com/#catalog/118/765/=kh3wau (No-crimp twist-on for stranded wire). I exclusively use the water-tight version on my motorcycles.

I am always suspicious of the solder ones - get a box of sealant lined heatshrink crimp butt splices. Also, get a decent ratchet or hydro crimper. The reason most people can't get a solid crimp that will pass a pull test is that they are using $7 lovely stamped sheetmetal crimpers that are about half a step up from mashing the crimp with a pair of pliers. Crimpin ain't easy, guys. Not without the right tools anyways

Use one like this at the very least. I have an AMP branded one and it's leagues ahead of the pliers-style type.

I've just got my hands on a bunch of cheapish Ni-Cd cordless tools that don't have chargers (ex-display stock, not stolen!). They have quite a range of battery types - 12v, 14v, 18v and the ones with the same voltage, don't have the same dimensions. I have a feeling that buying a complete set of chargers is going to be bad value for money - is there such a thing as a 'universal charger'? Something with croc clips or the like to connect to the battery packs?

This harness has been giving me nothing but problems and I'm way over thinking everything related to it at this point. Where's a good place to get quality butt connectors from? Would McMaster be alright (my mom works there and gets a huge discount)? All I have is some that came with a $10 "electrical kit" from Wal-Mart, which I don't really trust to hold.

Uthor posted:Is the HF tool "good enough". I really don't do electrical work and don't want to drop $40 on a tool that will just sit in my tool box. I have this one. I kind of suck at crimping wires, but I can manage good solid crimps with it, even with lovely terminals. Before that, I was using either the stamped steel type (worthless) or mashing it with pliers. Mainly because of this, I always preferred soldering + heat shrink tube on my wire harnesses. I did one this way in 1996 that I'm still using today in my beater, and it hasn't skipped a beat yet. The other thing I dislike about using crimped butt connectors on car stereo harnesses is that you end up with this big bulky pack of them in the middle of the harness that you have to wrap up and stuff out of the way, unless you think ahead and offset them so they don't all end up at the same point in the harness. If you will be crimping everything though, the best way to do it is to strip enough insulation from the wire to allow you to fold the wire back over the insulation, then feed the insulation + folded over wire into the terminal and crimp on that (if that makes sense). That way, you don't get a wire that breaks off just behind the terminal after a couple weeks.

The harness I have is supposed to be plug and play, but the ground wire and another get flipped between the two ends, causing a short and the fuse to blow. I will only need to use two connectors, unless there are other mixed up wires that I missed...

I saw a lot of arguments for both when I searched online, but the consensus was that a mediocre crimp is better than a mediocre solder joint, and I think I can figure out how to crimp correctly easier than I can learn to solder correctly.

I got one of the ratcheting crimpers from HF and the dies were garbage. I could crimp better with a pair of dikes. I splurged and got the Ancor ones that HF copied and it's a night and day difference. I like HF for a lot of things but their crimpers are not worth it. The Ancor ones were like 60 bucks but so, so worth it.

gently caress y'all. Just braid both sides of the wires together and make it look like a ponytail. Then wrap it in masking or painters tape.

Sir Cornelius posted:I somewhat really doubt properly soldered wires protected by a fitting heat shrink tube will crack from stress before a crimp gets loose. Both are valid options, and most people sucks at both. Properly soldered with real (high lead content) solder works fine. Low lead/no lead solder work hardens from vibration and cracks in many situations you'll be stuffing automative wiring. Even with a proper mechanical connection, proper solder and technique, proper materials, and stress relief on the joint (heat shrink, properly sized and applied) a proper crimp is well recognized to be a better choice in general. All of this depends on the quality of the work and tools, and even at that depends on exactly where the connection is going to be (location, vibration, environment). In general it's much faster and easier to get a good solid connection for your average mechanic or garage tinkerer with a selection of appropriate sizes and types of high quality crimp fittings and a good quality crimping tool. Solder if you like, but know that it's not likely to be a better solution. It's just going to take a lot longer to do well enough to equal the quality of a crimp. The only times I typically consider solder on wire splicing is for exterior items in the middle of a run that won't be disconnected again in an environment where any tupe of plugged fitting is likely to corrode and fail over time due to environment without using much more expensive weatherpak type connectors. Think under hood/under chassis wire repair.

It's just easier for wrench-monkeys to feel good about a lovely crimp.

Ouch man c'mon E: I've always twist-and-soldered my car stereo wires and never had one come loose, though I'm willing to play around with crimping. Won't be the same without the smell of burning wire insulation though.

I didnt read all the posts but people are talking about crimping. I am a senior in mechanical engineering and know a bunch about manufacturing and used to work in engineering at a milspec crimp tool manufacturer. I can answer literally any question about electrical crimping. To sum up my advice thus far in this thread: -For the price, HF's ratcheting crimp tool owns, the manufacturing quality isnt good but it can crimp stuff well. -It is dangerous to use HF's butt connectors. -ONLY USE UL LISTED TERMINALS. Autozone/Cheapest at Walmart/HF are not UL listed. -ONLY USE UL listed WIRE. This is very important.

Ferrules and terminal strips are where it's at. None of those goofy screw down terminals either, good ol' fashioned spring loaded friction grip type. Honestly, if room wasn't an issue I would love for my whole car's electrical to be done with cable trays and terminal strips. So pretty in control cabinets... Like Lord Gaga was saying, spend the money on your connectors and odds are the tool will be the least of your concern.
