I was giving my latest addition the once over when I came across this lovely piece of happiness.

The question was how do I get from that to this: 1b.jpg

with this in the way? The connector, not the rectifier diode. 1c.jpg

I was thinking that I would just cut off & replace the connector, but I couldn't find a part number. I was working through the steps I would need to go through to change the connector when I realized that the factory would need to crimp the pins onto the wire before assembling the connector. Surely they must have a release on the pins in case the new guy puts the wrong wire in the wrong hole. After much poking & probing, I found it.

Use a small jewelers screwdriver and come in from the front GENTLY. Don't tug on the wire until after the screwdriver is in all the way. It may take several tries, but you will find it. Once you have heat shrunk the wires, lift the lock GENTLY and reinsert the pin. If you get ham-fisted, you will snap the lock off.

This will also work on the larger boxy connectors.

If any of you experts have connector part numbers & sources, please feel free to share.


For those who care, the new addition is a Husqvarna LT125 (HC12542A), and the red & orange wires the alternator output wires from the Briggs 12.5 hp I/C Quiet.

Nice repair ! If you start doing more of this type of electrical repair these crimpers come in handy if you can get the correct terminal to go in the body . NAPA has a nice selection , Al

... if you can get the correct terminal to go in the body ...


Therein lies the rub. Anyone have part numbers &/or a source? Anyone?

Thank you for the crimper link. I will definitely look into getting a set, if I can find terminals ...

You might check these guys.....

Here's another company, but their website is a little hard to navigate. I've used litterally THOUSANDS of these when I was installing equipment in police vehicles.

Another trick to freeing up round pins in connectors is to use a piece of thin wall tubing that is just a hair larger in inside diameter than the pin. Push the tube down over the pin and it will force the locking tab out of the connector more easily than searching for the tab with a screwdriver.

Another possible source of pins/conectors is Radio Shack.

There are extraction tools for removing those round connectors. The generic name is usually mollex connector, but there are several sizes and only the right one will work well.

I have used a piece of aluminum flashing curled to be the same ID as the connector OD. In a pinch I used the sidewall of a Pop can (thinner is nice, but a little flimsy)

When taking these connectors apart, I find it helpful to push them a little further into the connector before trying to release the lock.

Nice tip, thanks for taking the time to write it up.

Nice tip, thanks for taking the time to write it up.



I wrote it up because I couldn't find the info anywhere on the Internet. I knew the experts had to know this stuff. It is, in the end, very basic. I wrote it for other newbies like myself (that & to increase traffic to the site :smilewink: ).

I'd still like to get a complete listing of the common parts like male & female pins & terminals, connector housings (2, 3, 4, 5 & 6 hole), etc. Packard 56, 57 & 58 terminals look like they may fit & Oregon make some stuff, but there has to be a source the experts use. Surely they don't just change an entire wiring harness, do they?

Hi Guys:

I'm new to the forum, but I think I can help with part numbers. Being that I work for an equipment rental and small engine service, I have access to manufacturers tech support websites.

If you provide me with model, type and code, from your Briggs I can probably get you the part numbers you are looking for.

I have had some luck finding odd connectors at Napa by taking in the connector I'm replacing. I keep one of the molex tools MH81 mentioned in my tool bag at work,it doesn't get used often but is invaluable when needed! I'm thinking it was 5 or 6 bucks at Napa.
