Could anyone tell me if this is possible and how I should go about it please?

I need to fit suppressed HT leads to a project with a DK4 cap - I would prefer to use the brass crimped ends at the plug too, any practical experience in this area would be very welcome.

Hi Ruairidh 

I bought a set of these a few weeks ago to try and solve interference with led indicators and an electronic rev counter.

They seem to work fine and have cured the suppression problems.

Cheers

Howard

I use a length of solid copper wire from a mains cable about 1-1/2" long. Push it up inside the cable then bend it over 90 degrees and bend it round in a circle flat against the end of the acorn.
has been working well for us for a long time.

That sounds perfect - have/can you do the same at the spark plug end as well Jim?

Hi Howard

Do you use the brass crimped end on the plug end.

I had problems with LED indicators which I eventually rectified by using suppressor caps. Whilst it solved the problem I don't like the appearance, I would prefer to use the proper brass ends
Buy an Austin 7 they said, It's easy to work on they said !

I just stripped the insulation and poked the grey stringy bit (technical term) through the brass washers. I think on the plug end I would have done the same and folded it back onto the outside of the lead before crushing the crimp, much as you would with copper... I like the idea of a strand of copper to beef it up.

Hi All

Photos as requested.  I bought two sets of leads, one to keep in the car as a spare. These are photos of my spare set.

The dizzy end connection looks secure but time will tell.  The plug caps are plain enough to look reasonably period.  However like Barry I would have preferred brass screw ends.

Hope this helps?

Cheers

Howard
