Pertronix plug wires

What kind of plug wires do you need to run with a pertronix setup I installed the pertronix in my M but was told that I need to change the wires or it will destroy the new ignitor

Solid copper wires, or Magnetic Supression Wires (real wire wound around a fiber core) Either have effectively no resistence. The more expensive MSW wires will have no radio static emissions. The solid wires will make radio noise. JimN

LN, I cant say for sure butttttttt I think what you were told is because they dont want the risk of any cheap inferior wires that may allow a HV arc discharge. I dont think its so much whether they are carbon core suppressor plug wires which reduce radio interefernce or plain old wire core as its the quality HV insulation they are concerend with. Often when people switch to an elec switch thay also use a HV high energy coil and run a wider plug gap which means they are operating at higher then stock firing voltages and worn or inferior plug wires may allow arcing. I think in some instances (more race cars prob not so much a tractor issue) where you use their high performance switches and super high energy HV coils and run wide plug gaps they actually want some impedance in the HV secondary and use spiral wound plug wires???

If you use a set they recommend and supply their warranty ought to be better Id think but just dont use any worn ratty aged wires n you will likely be okay

To get the most bang for the buck that elec switch has to offer I recommend a high energy HV coil (as specified by them to match their coil) and a somewhat wider plug gap with quality insulation wires. Just the elec switch with the stock coil, however, still gives improvement due to faster more positive (no points bounce and ringing) coil current switching.

CONSULT WITH PERTRONIX AND DO AS THEY SAY NOTTTTTTTTTT MEEEEEEEEEE

I had a petronix elec ignition go bad after 2 yrs. Just before that it ran rough and I finally discovered sparks jumping all over around the sp wires when viewed at night. I had the high voltage coil also. Ordered some high voltage wires from Brillman Co (online) which fixed the sparking and rough running problems. The insulation on these plug wires is much better. Don't know if the sparking contributed to the elec ignition failure. I may have installed it a little cocked.
