Yes, that is exactly what they told me and also what they put in their literature. Standard Pertronix cannot be compared to a Pertronix II or a Pertronix III. Yet - I keep seeing posts just stating "Pertronix" with no hint as to what specific version. Ohm load on the Pertronix is critical.
I suspect most Pertronix modules use on old farm tractors are the standard versions (version 1 but but just called PERTRONIX). It works fine with copper wires but MUST have at least 3 ohms on the primary unless it has an 8 cylinder engine. I fixed an IH last year that burned up two modules and the guy had a 1.2 ohm coil. Yet he blamed Pertronix? I just put one on my Ford 641 and the original coil is 1.4 ohms and the ballast resistor is 1.8 ohms. So, a total of 3.2 ohms which is fine. If I took out the resistor, I would likely burn up the module.

Today's Featured Article - A Belt Pulley? Really Doing Something? - by Chris Pratt. Belt Pulleys! Most of us conjure up a picture of a massive thresher with a wide belt lazily arching to a tractor 35 feet away throwing a cloud of dust, straw and grain, and while nostalgic, not too practical a method of using our tractors. While this may have been the bread and butter of the belt work in the past (since this is what made the money on many farms), the smaller tasks may have been and still can be its real claim to fame. The thresher would bring in the harvest (and income) once a y
