yellow wires

Postby GrimReaper86 » Mon Nov 03, 2014 2:10 pm



86 Aspencade

I noticed the other day the connector for the three yellow wires was turning a little brown. So, I decided to try to head off any problems before they start by cutting out the connector and solder the three wires. I have discovered though I have no talent for soldering. Does anyone think it possible to use solderless connectors and then apply solder to the wires and connectors? Maybe even solder the connectors together? I think I can do that little bit of soldering. I'm not happy at all with the way my soldering on the wires came out. Any suggestions would be appreciated.

Actually there are a couple of considerations when soldering...
First is that the wire should be clean shinny copper...The bike has a tendency to have black oxidization on every strand...I've had to scrape the strands to expose the copper...solder does not stick to oxidized wire and acid core solder should never be used...
After the stranded wire is cleaned,it can be dipped into rosin solder paste and crimped into a bare butt splice connector....then using a high heat soldering tool,flow rosin core solder into the joint...
I don't recommend a torch(open flame) or a pencil iron(not enough heat)...
A soldering tip that is heated by a torch is fine,just no flame on the joint.A good soldering gun works well...

As Virgil noted, most of the soldering problems people have with replacing this connector is oxidation of the copper. If the copper wires look black or green, solder is NOT going to stick to it, no matter how hard you try. You have one of two options: use very fine sandpaper to scrape the wires until they are shiny, then solder this - or cut the wires farther back until you find shiny, non-oxidated wires. This is what I did, and I then patched in extra wire to make up for what I had cut out.

If you have shiny, copper strands, twist them together to make a decent mechanical joint, heat the joint with the soldering iron, then touch the solder to the wire, the solder will instantly flow into the joint and fill it up.

There's plenty of videos of "how to solder" but I can't seem to find one that addresses corroded wires.
I've posted this quick video...


I picked the worst piece of wire I could find in the back lot.
Take note that I use rosin core solder and a sutable soldering iron for the heat needed.
A small pencil iron just won't do just,as a blow torch flame is too much.

Thanks VM... that explains quite a bit. I went back and looked at the soldering gun and found it was rated a 90w. Gonna pick up a better one and some of those connectors, practice a little more and give it another go.

A 90 watt iron may be enough IF you can get the connection hot enough.I use the 140 watt for the heavy wire.It got plenty of reserve .My 40 watt iron just isn't enough.
The 90 watt may take 3 times as long to get the connector hot enough to melt the solder.

Well,I just tried my Weller on a #10 wire with a bare butt splice...It does work...takes a few seconds longer than the 140 watt setting but I got plenty of heat for the job..
As always...remove the tip from the iron and clean where it makes contact with the mount...
Use only 60/40 rosin core solder...leave the silver solder to the plumbers and the torch...
clean copper wire is a must..take as much time as needed to get the corrosion off the strands by whatever means necessary...Solder just will not stick to corroded wire...

I had made a video a little while ago about soldering, and reading this reminded me that I had never taken the time to post it. So I have just posted it now: Electricity 101 Part 4: Soldering Techniques
