High Tension Leads

[Brad110]

I am updating ignition and have enquiry re leads. I wish to retain the side entry distributor cap with screw retainers for the leads.

Can I use modern silicon leads and do I need to use the metal crimp ends for the screw to make contact or is it sufficient to bare the central element/ wire and bend it back?

Or do I have to revert back to copper wire leads of old.?

What are your experience/ recommendation?

I have not tried to use the modern leads with resistive conductors in this type of distributor (and similar problems at the spark plug if you stick with the original connector/covers. You can get a connection with a 'U' of stiff wire (preferably bronze) with one leg pushed into the end of the wire and the other lying alongside it, but my inclination would be to use metallic core high tension leads - I think it is still available, although you might have to do a bit of searching. Although more reliable, it does have the disadvantage of radio interference.

Aren't the silicon leads to thick for side entry caps? W.

The leads fit snugly but I am trying to determine what is required to make contact with the terminals, use crimp rings as per coil connections or simply screw thru cable with core bared.

Thanks.

I would stick with copper-core cable - available still in Oz Onlineautomotive - Narva Copper High Tension Cable 7mm (http://www.onlineautomotive.com.au/Narva-Copper-High-Tension-Cable-7mm)

Hi

I would not use anything except the copper cored stuff . Repco does have it, but you have to ask them to order it and they sometimes want you to buy 30 metres of it :eek:

A tip: If you are stuck somewhere with a faulty ignition HT lead . Grab some TV or CB coax antenna lead and use it as a temporary fix - it will get you home .

Coax has a thick nylon insulation with copper braiding around it , and it will work Fine .

I have found the copper core at Bursons and Repco

$1 per metre.

Thanks

Looks like the vote is for copper, I agree. I thought Silicon was for implants.

PS Fencing wire works fine but a bit tricky under the hood with motor running.
