In running a Lucas Comp magneto on a 60s Velocette Venom. It has a Lucas plug cap and runs solid core wire from the pick up to the cap. What should be the resistance? should a resistor cap be used? I looked at magneto man's thread....but didn't see a discussion on magneto HT leads. Maybe I just missed it???
TIA
Mike

The technical answer is 4/5*square root * bugger all.

Don't use a resistor cap or lead.

Yeah,

Solid core HT over a short distance should be close to nothing.

I’d ditch the resistor caps as well.

set up now has resistor cap, non resistor plug. I'm not sure what should be there "stock".

No resistor cap. No resistor plug. Yes, copper or other metal plug wires. No folks with pacemakers!

Stock was non resistor everything, resistors only first came in when radios were fitted to cars and emf interfered with the radio until resistors were fitted. So unless you have a radio fitted then go non resistor with a Magneto.

No resister cap with Magnetos, you can buy Lucas non resister rubber plug caps

And solid core, as in metal, plug wire.
No resister core.
