Scotty, Apparently you have tried a couple of resistors on your tractor? The way a resistor works, it has to be powering a load (Current flowing through it) to show a voltage drop across the resistor. You must have checked the voltage on both sides of the resistor with the breaker points open, so there was no current flowing in the ignition circuit. That is why you got the 12 Volts in and out. If you still have one of the resistors, try it again, and start the engine, and use an analog voltmeter to check the voltage on the switch side of the coil for the 5-7 Volt range I posted before. If you are within that range, you SHOULD be OK. The reason for using the analog voltmeter is that a lot of digital meters will be affected by the EMF produced by the ignition and charging system, and may go "nuts" and read incorrectly. An analog meter is less sensitive to the electrical "noise".

Bad Vibes - by Curtis Von Fange. One of the strangest ways to communicate with our tractor is to ask it how it feels. "Ask it how it feels," you say? Yup, ask it how it feels. Now, as with the other articles in this series one has to be able to hear what 'ole blue' is trying to say in response. The nice thing about our old iron friends is that they are usually quite consistent in their response, rather unlike some people I know who might change what they say due to the weather or other mitigating circumstances. But since t
