Part 8, Attaching to coil
The sparkplugwires or HT leads supplied with my
XA sparkplugcaps are quite thin (5mm) and I have had a few questions
about how to attach them to the coil. Well, as they say, a picture
is worth a thousand words, so here are some pics!
First of all, the HT leads supplied
are probably too long so determine the required length and then
add about 40 mm before cutting them off. (20 mm extra for each
side of the HT lead) How to do the sparkplug side of the lead
you can see on the previous page, so
now I will just explain the coil side.
Make a little cut in the insulation 20 mm from the end, taking
care not to cut into the copper. Bend the wire back and forth
a few times to expose the copper core and remove the insulation.
Put the clampnut and the rubber on the wire now.
Twist the copper core strands a few times, fold the core double
and then fold back against the insulation. You fill find it now
fits nicely in the coil, use the clampnut to fix it in place.
If you have a different coil (almost nobody has the stock XA
coil anymore) or just want it even tighter, you can wrap some
insulating tape around the end of the HT lead's insulation and
then fold back the twisted copper core. I tried this on a stock
coil and it gave a super tight fit! By the way, the coil in these
pics is from a 45" flathead, which is very similar but slightly
higher than an XA coil.
