Going to replace some frayed original wires on the SA - coil, lights,etc.
The original wire from coil to dist. is silver.
Is there reason to prefer copper vs silver for conductivity or interference.
Thanks,
Dell
 
Likely, the wire is just tinned copper and a new copper replacement wire will be just fine.

The exception would be if it is a 12 Volt conversion and someone has used a resistance wire lead (as some cars and trucks did) install of a discreet ballast resistor.

If it is still 6 Volt, no worries!
 
That wire is only silver in color not in what it is made of. A true silver wire would be worth way to much to ever have been used on an old tractor. Or in other words copper is copper just been tinned in your case and lots of other places
 
Im like Bob, sorta doubt its really silver, but if so that or replacement copper (whats Id also use) are both good electrical conductors. As far as radio interference where resistive carbon core suppressor wiring is used, thats more for the high voltage like coil or plug wires. While youre only looking at 4 or so amps from the coil to distributor (primary low voltage wiring) Id still use 14 or 12 gauge with crimped and soldered terminals..

OOPS do you mean the HV cable (coil wire) from the coils center HV output tower to the top center of distributor cap orrrrrrrrrr the small wire from the coils small output terminal to the side of the distributor?? REGARDLESS copper is fine, a standard copper wire core high voltage "coil wire" will work. In cases where radio interferene is an issue, thats where carbon core resisitve coil and plug wires can be used however.

All my tractors are stock -6v.
Not replacing plug and coil wire. Just smaller stuff.
Will follow your expertise.
Good stuff. Thanks.
