Hello first time trying to get this 1950 Ferguson TO-20 tractor running in 8 years it’s still the original 6V positive ground. What I’ve done so far new battery, new coil(was told 12V coil will work), new plug wires, new distributor cap. I can’t seem to get any spark, I took an electrical tester and I have power on both sides of the coil, and from the positive terminal on the coil to the distributor housing. Still no spark, so I tried taking a wire from the battery to the negative end of the coil. Still no spark, taking the wire from the coil that goes into the distributor cap and holding that to the engine block while cranking there isn’t a spark. Taking the cover and rotor off and seeing the points and condenser which appears to have been replaced. I can spark between the points by taking a screw driver and arcing between them. But I still have no spark!!! Does anyone have a idea why this would be, thanks in advance.

I have the same tractor and have done everything you have. With the exception that I have a 6v coil and still no spark! I also removed the ground wire from the battery and cleaned the contacts. Engine will turn over but no spark. Do you ever solve your problem?

I wonder if you have replaced the plug wires with the new modern type? I think they all call for copper core wires on these things.
Maybe someone can chime in on that.

That is a good question.. I’m not sure but will check my plug wires here in a few minutes. Knowing my luck I thought I had just bought a bad coil. So I went to the local tractor store and bought a universal 6v coil and same result. Shouldn’t the voltage coming out of the coil be higher than 6 Volts?
