Electrical connectors
« on: April 15, 2015, 07:48:53 AM »
Hi Everyone,

Can anyone recommend what wire connectors to use when making my wiring harness from scratch?  I have a buddy who recommends the andersen connectors but it seems to be overkill to me...  Im also wondering what to use in place of the bullet connectors that plug into the 4 female bullet connectors in the headlight bucket.  I mean I can use the standard male female spade connectors etc but im wondering what works well for everyone?

Cheers,

James

Thats great and all but the prices are not.  Im also not doing a nut and bolt restoration.  The price of those connectors plus the cost of wire far outweighs just buying a new stock harness...

Other places also sell the connectors.

vintagecb750 (Canada)
cb750supply (USA)

These two are the same, really... just where their shipping originates from is different.

I didn't think their prices were that bad. but then again I restore a lot of bikes so it's handy to always have what I need on hand. and those crimped connections are superior to the parts store stuff.

What is wrong with the 4 way connectors? They seem to work very well and do minimize the number of connections a person needs.

The price of those connectors plus the cost of wire far outweighs just buying a new stock harness...

The connectors everyone is referring to are designed for a "double crimp" that actually rolls the edges of the connectors into the wire. It also does the double rolled crimp on the insulation at the same time. Of course, they do require the $35 crimp tool, but the finished connector looks and performs as well as the original connectors. My experience with the single crimp "squash" connectors is that they are not very reliable and tend to wiggle loose and or fail at the most inopportune times. Peace of mind is priceless when you're accelerating onto the interstate as opposed to having intermittent electrical gremlins rearing their ugly head just when you most need your electrical system to perform as expected. Troubleshooting electrical problems is also much easier when you can eliminate as many variables as possible. Another perk is that you can get the right size connectors to match the stock connectors that remain, such as turn signals, alternator stator coil, handlebar control switches, coils, ignition switch, etc...

What is the motivation for the custom harness? Was the original damaged beyond repair? I have refurbished several stock harnesses that were in pretty rough shape:

http://forums.sohc4.net/index.php/topic,137351.msg1549191.html#msg1549191

and I only replaced those connectors that couldn't be saved. I too was uncertain as to whether or not to go this route, and looked long and hard at replacing the complete harness, but after I made the first crimp I was convinced I had made the right decision. I don't even use the single crimp "squash" connectors anymore, even the connectors on my automobiles get the Vintage Connections treatment.

Very very true. I've often been tempted to rebuild my Brit bike harness with these connectors, but I'll keep the true to Lucas form.

I understand your points...  But its just a simple system with a birds nest in the headlamp bucket.  It would be nice to clean that up and also throw a headlamp relay etc into the system.

Im looking for a way to replace the female bullet terminal connectors (1 into 4 type of connection in the headlamp bucket) with something a little more streamlined.

In regards to the crimp on style of connectors, they can aways be soldiered afterwards.... 

I also found cycleterminal.com as a source of OE type connectors...

Cheers,

James

Ok so this is what I ended up doing.... 

I went to http://www.cycleterminal.com/  They have a lot of great stuff and the guy is in NJ (Im in NY so shipping is fast) and he responds to emails in a timely fashion.

I have to use 3.9mm bullet connectors to accommodate my 14 awg wire (So all connections will be using that). 
Honda used 3.5mm which he has as well...      http://www.cycleterminal.com/bullet-terminals.html

He also has a honda rectifier plug...  If you scroll down 3/4's of the page to just past where it says system specific in red, you will see it.

and I picked up a few other 250 series connectors...  http://www.cycleterminal.com/250-connectors.html

Thanks for talking some sense into me.  Its a boring day at work and I was driving myself a little crazy trying to get all my parts ordered to get here by Saturday... (The gf is on a business trip and I have all weekend to myself with the bikes)  so I want to get a lot done.

I've used cycle terminal also. Great fast service (I'm in CT). I got the 3.5mm bullet connectors for my 550, crimped and soldered them. I didn't get the special crimper but you can make do with a regular set of crimpers and solder. I also sprung for the adhesive lined heat shrink, awesome stuff and it's like a 4-1 shrink ratio.

Easy Dave, I wasn't bashing yours!  ;)  It actually looks pretty good. The purpose built tool for the "double crimp" looks like a factory crimp when complete and there's no need to break out the soldering iron(s) to finish it. I don't mind soldering, I have more than one soldering iron and have soldered everything from roof flashings (BIG iron!) down to printed circuit board components (little iron) and I keep heat shrink tubing within reach. But I'm more lazy than I am cheap (and I'm pretty cheap)! If I can eliminate a step, I'm all in!   8)

I am a cheap arse myself - i.e. I did not buy crimpers - but you can do it  with good needle nose pliers.  I lost few before I learned though.

James, did you spring for the crimp tool? I cringed when I bought mine but I'm glad I did. I'll post some picts this evening of what the crimp looks like when using the right tool.

Haha, what? That's no good!?

Easy Dave, I wasn't bashing yours!  ;)  It actually looks pretty good. The purpose built tool for the "double crimp" looks like a factory crimp when complete and there's no need to break out the soldering iron(s) to finish it. I don't mind soldering, I have more than one soldering iron and have soldered everything from roof flashings (BIG iron!) down to printed circuit board components (little iron) and I keep heat shrink tubing within reach. But I'm more lazy than I am cheap (and I'm pretty cheap)! If I can eliminate a step, I'm all in!   8)

Haha, just kidding around. This was actually one of the better ones. But they're all strong and I don't think I'll have connection problems any time soon. But yeah, the right crimper tool is a sure fire way to get a good crimp every time. But not for those of us who are cheaper than we are lazy!

Alright, picts as promised:

Strip it. I usually strip about a 1/4" to 5/16". Three-eights is a bit much and not necessary:






Don't forget the insulator! (ask me how I know):




I finally figured out (after about three tries) that it's easier to load the connector in the crimp tool first. Note the stepped jaw. The trailing end has a higher relief so as not to over crimp the insulation:




Ratchet down on it just enough to hold it:






You only need about a 1/4" of insulation extended into the connector. Too much and you get into the part of the crimp that should be catching wire only. The jaws are pretty wide and hard to see inside, so I use my thumbnail as a guide when inserting the wire:






Crimp it!:




Viola':




And finally, the insulator:




Procedure is the same for other types of connectors, just be sure to use the right insulator. Here we have the insulator for the female bullet:




Load the tool:




Crimp it... crimp it real good... and viola'!:




Slide the insulator into place:




Dang! This is how they must of looked when the bike was new!:






Give the wire a tug when you're done. Occasionally I will get a loose crimp, but most of the time it is a result of smaller gauge wire. In those cases I will strip 1/2" of insulation and double the wire back on itself to mimic a heavier gauge wire. These are my go-to connectors for all things automotive.  8)

For really small gauges of wire, like those attached to LEDs, I'll even fold the bare wire over the insulator itself thus allowing BOTH sets of wings to crimp onto the insulation.

Long story short, I started doing the wiring, then stopped and just used the stock harness for now...

So I have a bunch of wire and connectors for a project at a later date.  I started with the points wires going to the coils and stopped.  I had took off all the original electrical tape from the harness and realized it really was in good shape.  For now....  Till I have lots of time.

I couldnt find a crimper like the one shown locally and my buddy didnt have the right one, nor did the IT guys at work.  I went to Sears though, who apparently was closing down for good... and got a 1hp crafstman buffing wheel/grinder for $55 !  So im glad I was out searching for the dang crimper!

I did buy one of the automatic wire strippers from my local hardware store and it works great.  Ran me about $25

And this is the crimper I bought for $20 at my local townie auto store thats been around since like the 20s...  The sad thing is I think I have one at my dads house in his tool box already....  :(  http://www.amazon.com/SK-7703-Ignition-Crimping-Plier/dp/B0009WRL1U/ref=sr_1_18?s=hi&ie=UTF8&qid=1429546457&sr=1-18&keywords=automotive+wire+crimper

This does the same exact crimp...  Its in the top part of the tool.  It handles the inner crimp perfectly.  Its not perfect when doing the outer crimp that helps secure it to the plastic sheath on the wire...  This causes it to be harder to put the plastic weatherstripping part of the crimp connection in place due to it not being a perfect shape.

Maybe use the inner crimp portion of the tool for the outer crimp on the insulation, just stop short and don't "drive it home"?

Yea I see what your saying.  The first two I did came out great.  The part of the outer crimps that actually get crimped looks fine, its the back side that gets jacked up, sort of doubles over on itself as the crimper isn't as thick as the outer crimp is and it sort of ends up making an L shape if that makes sense, on the back side.  So when you are pulling the plastic clear weather strip over it to get the outer crimp to fit in that grove in the plastic, you have to really force it to get there. 

Anywho, I could make it work for sure, just at a later date.  lol

Ok quick question...  On the multi crimp too that I linked to in my last post...  I was using the smaller crimp to do the inner part of the crimp that physically crimps to the bare copper wire, then I was using the larger crimp on the tool for the outer crimp that goes to the plastic part of the wire...  I havent tried to the smaller crimp on the tool to do the same thing.  It might work...  I will report back for posterity of this thread.  Hopefully
