Hi Biff,
Is it possible that when you insert the plug wire into the connector it
doesn't make good contact? Or the wire slips out of the connector a bit later?
Do you strip some of the insulation away? It seems likely that there might be
a gap allowing the high voltage to arc inside the connector, and burn up the
wires.

I have a poser for the list concerning my ATV. It took me awhile to discover
this problem but it has me baffled all the same.
I have been trying to get the motor running right for some time and have been
replacing bits along the way. I would get it running but after 5 - 10 minutes
it would start missing and then I would lose all spark. I've checked or
replaced all the electronics, stator, voltage regulator, CDI box (ouch), and
coil. What I finally discovered was when I lose all spark the problem is at
the end of the coil wire from the coil to the sparkplug plug. The plug end
has
one of those screw in hard plastic caps and when I lose spark and unscrew the
plug cap the copper wires inside where the screw goes into the coil wire are
all scorched and broken/burned off for a 1/4" or more. I've shortened the
coil
wire until I get clean copper wire but after running again for a few minutes
the wire is again all blackened and broken. What could be the cause of this?
At first I thought it might be the coil but after testing it cold and hot the
readings are to spec. I am open to any suggestions.
