Sorry this has taken so long but have been out all day in a tractor seat. Just came back in for dinner or supper whatever you call it.
I didn't use a diode or the light shown in Bob's diagrams but used a resistor instead. I read somewhere they worked fine and I obtained it at Radio Shack. It was a 10 ohn rated at 10 watts and came in a package of two for about $2.00. I put it in the circuit where the warning light is shown. It is a ceramic style resistor and very robust for field use on a tractor. I also used a Chrysler RU12 ballast resistor instead of the one noted in some of the articles as it passed more current to the coil. The RU12 was running 5.6 volts through the coil and the one I saw in some conversion articles was only passing 4.3 volts. Hope this helps with your tractor.
