TIPS Extending broken spark plug wires

[mikerecike]

If the wire is sealed into magneto - not the screw in type..how do you join an extra short length on??

Crimp connectors then heat shrink?

Cheers.

You used to be able to get a double screw in joiner.

 

What ever you do, just make sure its well insulated for the voltage it will be carrying & sealed against moisture.

Hi, google auto electrical supplies and type in "HT connector" it`s a bit clumsy but might do, cheers

It may be possible to push a pin in to both bits of HT wire and then use heat shrink around the join. You can get some that glues as well as shrinks or use a smear of superglue or some other glue that will bond plastics/rubber.

 

Test it by sticking your tongue on it:sneaky2:

 

Nooooo don't, it will kill you - a damp finger perhaps when running but it will damn well hurt if it is leaking - you could slide a length of large fuel line over the repair after applying superglue to the area to join. that would probably be my favourite method!

Cut the head off a wood screw and use as a joiner and then use some heatshrink over the top and/or maybe some self amalgamating tape.

Its certainly a get you thru until you can sort it but it will last.

A couple of weeks ago someone posted a thread on Sugru mouldable glue maybe you could strip back and solder new bit on end then mould glue around join. Just a thought.

Thanks very much chaps.Some good advice here.Appreciated.

Join the wires by whatever means, twisting, soldering, thin screw etc. It does not matter how as long as they are joined.

 

This stuff will insulate them nicely. It will stick anything to anything, will repair fuel tanks and oil tanks, will 'cap' damaged rubber plug gaps and will rebuild the rubber insulation of HT leads.

It is brilliant, and IMO an essential workshop item.

 

The downside is that you never use it all up before it goes hard in the tube, but the hardness starts from nozzle end so my tubes all end up being stabbed with a screwdriver to get the stuff out. Even so a tube usually lasts me about 8 weeks of small repairs.

 

Its around a fiver a tube, I buy a case at a time from Cable Ties Direct

Thanks Barrie. On order - will give that a whirl.Appreciated. ps not sure what the woodscrew trick is?? Take the head off and sharpen so it's like 2 pointed ends? Then screw in both ht leads to make the join?;cheers.

[GardenKit]

Yes, but I would try a very thin self tapper about 20mm long, cut off the head and sharpen to a point. Use grips to screw it into one end of the HT lead, then twist the other end on.
