  • Ford 8n 1952 not starting, no spark
  • I would appreciate any help that you can give me.

    I bought a 1952 ford 8n for about 4 weeks now. It was running excellent for the first two weeks and then it decided to quit on me while I was riding it.

    I checked for spark and it had none. Not from the spark plugs nor from the coil itself. I checked the voltage to the coil and it had a solid 12.65v. thinking that it was a coil issue i went ahead and bought the pertronix coil,flame thrower 3ohms, part 40511, and also the electronic ignition for the distributor, part 1244a, so that I don't have to do the point and condenser maintenance anymore. Anyway, after i put in the new coil and electronic ignition, the tractor still doesn't start. I still don't see any spark coming out of the coil. I am running out of ideas. I hope some one out there may be able to help me.

    My ford 8n had already been converted to 12v before i bought it. It doesn't have any ballast resistor anymore after the conversion. Everything looks shining new from the battery to the coil and distributor cap, wiring and spark plugs.

    I also did a scratch test of the coil negative terminal to the ground and the coil would not produce a spark when it is on the tractor but if i take the coil out and did the same test in isolation with my battery starter pack them it would produced a bright blue spark.
    Thank you for all your help.

  • Try a direct jumper wire from positive (ungrounded side) of battery to input side of coil (currently tied to ign switch).

  • I tried a direct connection between the battery and the coil and it still didn't work. I spent half a day toiling with the coil and the electronic ignition and it got me no where. Then a friend came over. He is an 80 year old tractor lover with more than ten tractors of different kinds in his barns. He didn't like my electronic ignition conversion and urged me to go to Nappa to buy the condenser and point to replaced the ones that i have. Since I was running out of option so I listened to him. After swapping out the electronic ignition then the tractor is working again. I am so happy to see the tractor running again. I would have like the electronic ignition better because it is simpler and doesn't require much maintenance but at this point I just need to have my tractor back working again.
