My Deere 1010 crawler has wear problems inside the Delco distributor. The rubbing-block cam for the points is rusted and very worn. Rather then search for used parts - I figured it would be easier to buy a "breakerless" kit and just slide a reluctor wheel over the old cam.
But - after reading what little tech info Pertronix provides, and then talking with their tech department - I'm kind of disgusted with them. Mabye I'm missing something here?
First of all - with many older tractors only the standard "Ignitor" kit is available. This kit claims "higher voltage" yet MUST be used with a 3 ohm coil only. It cannot handle a 1.5 ohm higher-energy coil used in many cars, trucks, and tractors. It will burn out and void warranty. This fact got me confused. They say for best results - use their "40,000 volt" Flamethrower coil that is 3 ohms, not 1.5 ohms. So, I guess if it was special made with a higher ratio of primary-secondard winding turns it might be possible. But I cannot find any real specs on these Chinese coils Pertronix is selling. When I called their tech line and asked about the 3 ohm-coils-only thing - they told me they sell a special 2.8 ohm coil for tractors and crawlers. Part # 28010. I asked about the ratio of coil windings and got no answer.
So, as far as I can tell, the OEM Deere 1.5 ohm coil - used with a bypass resistor system is probably just as capable of higher voltage as the Pertronix - and maybe even higher?
Oh well. I'm not going to buy something that lacks proper tech info. Even their "new" catalogs" are dated 2008 and 2010 which is kind of strange. Last I checked, this is 2012.
I'm going to make my own breakerless high-energy system that allows a low ohm coil. I'm going to rob parts from a 90s Chrysler four-cylinder engine. I see that many tractor pullers do the same. Once done, all parts are generic and available from any auto parts store.

Today's Featured Article - Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
