The coil to distributer wire ohms @ 500. We are runing solid core plug wires. The cap is good. The ground wire in the distributer to battery ground ohms @ 0. Among the various coils burned includes a pertronix 3 ohm. It starts and runs great. This is a loader tractor so it gets lots of idle time. My question is directed to anyone who has had this problem. What was the cure for you? TIA [Reply]   [Send Email]

His explanation was that their igniters do not work well with solid core copper wires and doesn't recommend using them. The rest work fine. It has something to do with noise being created with the solid core and the microprocesors in the igniters.   [Reply]   [No Email]

Check with them for coil and wire suitability that matches BOTH your switch and coil. Some companies manufacture spiral wound plug wires which "theoretically" could provide some degree of inductive impedance in addition to higher resistance over the regular straight wire core, IF ITS REQUIRED????? It seems there are all sorts of options offered for super high energy exotic ignitions used on high RPM high compression race cars, but those probably arent needed on our old low compression lower RPM tractors. Burning up coils sounds like excess current which obviously over heats them as they cant dissipate that much heat. Id just give Pertronix Tech Support a call and trust what they have to say versus what we say on the board (if you havent already) Best wishes n Good Luck John T   [Reply]   [No Email]

The original Ignitor I makes no more spark voltate then the original breaker point setup. If you've got the Ignitor II system, it cannot be used with copper plug wires.   [Reply]   [Send Email]
