Reply With QuoteLeads sometimes go this way when heat affected, usually due to a poor connection between the core & terminal which creates high resistance.

I have change this lead alreay just wondered if anyone could shed some light as to why the distributor cap end had changed colour, other leads seem OK

Yep, the lead is fried, good thing you threw it out. I see this quite often with silicone suppressed leads. Less common on spiral core types. Just pull the end connector off and see if the conductor is still present, or burnt away.

makes sence, I already swapped out the distributor cap so cant look at the contacts.
just debating if its worth getting all new leads if one is stuffed the other might be the others look ok maybe im just being a tight bugger

Do the lot. Would suggest you go down the Magnecor route also.

I agree - if one lead is faulty I would replace all. Suppressed high tension leads usually fail, as this one has done, where the resistive core has sparked to the metal end termination (probably due to moisture causing corrosion). Once sparking starts it destroys the core, and this destruction progresses back along the lead, the heat involved changing the colour (I wonder if this is intentional as a trouble shooting device?) until the overall resistance of the core leads to ignition failure for that cylinder, starting with an occasional miss.
