I have a 55 640 that I ve owned for eight years. Before I got it, it had been converted from a points system to an electronic ignition. I can t see a brand name on the ignition to tell the brand. The tractor had also been converted to 12v with alternator, battery, lights, etc. changed. I m putting in new plugs, wires, etc. and also wanting to put on a new coil. Right now, it has a coil with an external ballast resister attached to the engine block. The coil is so rusted that I can t get any identification off it.
Can someone tell me what coil I should be using on this with the various changes that have been made to the tractor? Should I use a 6 volt or a 12 volt? What about the ballast resister? Is it needed if the coil has an internal resister? Or, is it needed at all with the electronic ignition instead of points?
Any help/advice is appreciated, and thanks.
