Ouch. I'm tying up the wires behind my panel and found this one with damaged insulation. It is the mic key wire on a com radio.

Is there a way to repair it?

No image attached; did you intend to send one? In any case, if it's a single conductor with no shield, you'd have several options. Replace completely (best & most hassle), or snip out the bad section & replace with a good length of wire, using butt splice crimps or lap solder joints with heat shrink, or cut it once near the damage & slide heat shrink over it, long enough to cover damage and the repaired cut, or, wrap the damaged area with quality electrical tape. 

Those are options that came to mind quickly, more or less in descending order of desirability. The last, while not sounding great, could be done in a fashion that would be 'safe and effective'. Just not pretty. It worked for decades in 110/220 volt house wiring to make up joints in electrical boxes, before crimps & wire nuts became common.

Just saw the pic. If that's a subD connector with removable pins, use a pin extractor to back out the damaged wire, cover the damaged area with heat shrink, shrink it, and re-insert the terminal in the connector body *If the pin isn't removable*, I confess I'd be looking for a roll of quality electrical tape. Everything's a compromise, and that would be one I'd be willing to make, though I realize others would not.

Art,

<< removable pins,..back out the damaged wire, cover the damaged area with heat shrink .. pin isn't removable*, I confess I'd be looking for a roll of quality electrical tape >>

An even simpler way is to buy some Liquid Tape in the Automotive section of Wal-Mart. Even if the wire is buried deep you can reach it with a small artist's brush. This product forms a durable, tough rubberized coating.

Art,

What Charlie suggests is entirely adequate and as long as the wire strands themselves weren't damaged (the photo seems to indicate they aren't) then heat shrink will probably last longer than the radio.

Having said that, I'm a perfectionist and on a new installation I'd replace the whole wire. If the whole run is a nightmare to replace, I'd splice in a new wire part way down the bundle - making the new wire long enough to get the butt splice into an area where both sides of the splice can be supported without putting undue strain on the wire/splice.

If for some reason the pin can't be removed, an alternative would be to cut the wire at some handy point down the wire bundle and sliding the heat shrink back up the wire to the damaged point. Then butt-splice the wire back together. Choose the splice point somewhere along the bundle where both sides of the splice can be supported to minimize stress on the splice.

I find that E6000/shoe goo works as good or better than most sealants
and is less invasive as long as significant corrosion hasn't started.

Thanks everybody. Tomorrow morning, I will see if I can extract the pin and add a piece of heat shrink. If not, I'll try a dab of E6000.

Hi Art;

Presuming you con't disconnect one end and slip some shrink tubing over it, there is a material called liquid adhesive tape, which can be painted on (much like white-out). It even comes in different colors.
Cheers! Stu.

FWIW Art, you absolutely must have the right pin extractor tool to get those D-sub pins out. Available from our friends at B&C (link below) as well as Digikey, or Fry's.  It is simply not possible to make do without this tool. (now watch me eat my words as somebody posts an alternate means of pin removal)

Use of a Raychem enviro-splice could avoid Pin Extraction if you have access to the correct crimper.(Aircraft Spruce).

Ken,
Who knows. I have been assembling the wiring behind the panel, and there has been work going on with sheet metal to support the top of the panel. That connector is right up near the top so it would have been easy for something to nick it. It was no big deal to extract the pin, add heat shrink tubing, and reinstall the pin. Since the windshield is not yet installed, the connector is easy to reach.
Cheers,
    -- Art Z.

I have used a piece of brass tubing to extract pins.  I have also used other less sophisticated methods to painfully extract pins.
Pin extractors are also available at local auto parts stores and possible in the aircraft electronics department of the big box building supply stores.

I find that E6000/shoe goo works as good or better than most sealants and is less invasive as long as significant corrosion hasn't started.

Art,

What Charlie suggests is entirely adequate and as long as the wire strands themselves weren't damaged (the photo seems to indicate they aren't) then heat shrink will probably last longer than the radio.

Having said that, I'm a perfectionist and on a new installation I'd replace the whole wire. If the whole run is a nightmare to replace, I'd splice in a new wire part way down the bundle - making the new wire long enough to get the butt splice into an area where both sides of the splice can be supported without putting undue strain on the wire/splice.

If for some reason the pin can't be removed, an alternative would be to cut the wire at some handy point down the wire bundle and sliding the heat shrink back up the wire to the damaged point. Then butt-splice the wire back together. Choose the splice point somewhere along the bundle where both sides of the splice can be supported to minimize stress on the splice.

Meh. Pin tools are cheap. Five bucks if you can't find one locally https://www.steinair.com/product/insertionremoval-tool-for-standard-d-sub-pins-mil-spec/

I have used a piece of brass tubing to extract pins.  I have also used other less sophisticated methods to painfully extract pins.
Pin extractors are also available at local auto parts stores and possible in the aircraft electronics department of the big box building supply stores.

>>now watch me eat my words as somebody posts an alternate means of pin removal<<

Yeah...start munching! <G>
I made one years ago when I was working for a living using a very thin brass tube the right diameter and soldering a T handle to it. Still have it somewhere around here, and use it when needed.

FWIW Art, you absolutely must have the right pin extractor tool to get those D-sub pins out. Available from our friends at B&C (link below) as well as Digikey, or Fry's.  It is simply not possible to make do without this tool. (now watch me eat my words as somebody posts an alternate means of pin removal)

Thanks everybody. Tomorrow morning, I will see if I can extract the pin and add a piece of heat shrink. If not, I'll try a dab of E6000.
