Pertroniix problem

Hayfarmer · Jun 14, 2009

Have had one of these on my SMTA for several years and it has been trouble free. Today I was pulling a 12 foot swather in fairly heavy hay, a load for the tractor. The tractor started to miss under load, but would run fine with no load. I checked a number of possibilities, cleaned the inside of the distributor and all. When I started it up again it would run for 2 to 3 minutes under load without missing. I realized if I just shut the tractor off for about 1/2 minute, then restarted it it would also run for the same time. I decided it was the ignitor unit in the distributor. When I changed back to the points and condenser the tractor ran fine. Is this a common way the units fail? This tractor sits much more than it runs so wondering if I would be better off to just stay with the points. How often do these units fail like this?

It sounds like the module is heating up and failing, POSSIBLY from too much current.

WHAT is the coil's primary resistance and what resistor(s) (if any) are used with it?
