Copper continues to conduct well unless it is broken. It is the connection points—at the spark plug and the ignition coil—that can introduce resistance. You can check the insulation in the dark while the engine is running; any leaks will appear as a faint, smoky, neon-like glow. Cleaning the exterior cures it.
Furthermore, the radio interference caused by copper wiring can potentially disr...

Opposition isn't power in the face of a large majority.

Would you prefer Labour remain in power?

Mine are bumblebee

Like Bob my copper core ‘Bumblebee’ leads are over 20yrs old.
The Green Sparkplug Co is my go to for plugs, leads, &c

Guy if you are still looking for gauge there is one on ebay just seen it starting at £63 no bids 4 days to go

I agree with Anam. Copper cored leads usually last quite a long time. I have had mine over 20 years and the continuity is still excellent. The stiffness can be down to the PVC covering getting less flexible over time. If it works ok then leave it!!

I may have done in the distant past 😉

But, no, my comment was more about stating how important it is to have a viable opposition. I'd much rather that was Conservative than Reform.

But I also think Trev has a point about the quality of leaders.

When I recently replaced the electronic ignition module I fitted a new Distributor Doctor cap and rotor arm. Have got new wire but couldn’t crimp the coil fitting. Did buy an Accuspark crimper ( the 2 piece type) but it is rubbish, the fitting keeps coming off when I pull the wire from the coil.

Copper over silicon everyday.

The end connections might fail with age due to oxidisation or bad contact, causing arcing, or no spark at the plug at all. But the wired core won't fail unless mechanically stressed/damaged/broken.

Other than that, the outer insulation can break down.

Yes continuity end to end with an ohm meter. Your meter will read less than 0.1 ohm, unle...

Les, I'm pretty sure they used a multimeter, though I wasn't watching.

I would never have found it and didn't even suspect that there were any issues with the ignition. I'd be surprised if Peter hadn't checked everything out before putting it on his rollers.

I tend towards "if it seems to be going OK then leave it alone" - though I would probably buy in a spare set of leads and d...
