  • 9N no start
  • Hi Guys, long time since last post,

    1940 9N 6V No Spark

    She sat all summer, thought I would get her ready for snow. A while back I had picked up some Echlin points and new wires so why not.

    Pulled distributer, put points in, ran card stock through points, set points at .015, cap looked new (I think I replaced that last year),I did not have a new rotor or condenser for some reason.

    As per a post I found from Bruce I tested coil, distributor, points and everything else he said, just the way he said it. All checked out good.

    Went back out put back on with the new wires, jumped the battery with truck the way Bruce describes in 75 hints.

    Great crank, still no spark.

    I don't think there is a way to be 180 out, wires were attached 1243 - front to back, no pop over of any kind with ether.

    Should I jump key switch, not sure what to test next.

    Thanks in advance

  • Heres a simple test you can use.Switch on,look at tractors ammeter.Crank enoine.Meter should flick back and forth 0 to 4 amps.If meter sits on zero points are not closing or are dirty.Swtch could be bad or coil primary open.Dad taught me this around 1942 on his Model A Ford when I asked htm why the needle flickered when the engine was cranking.Make a note of this.Im 80 years old and may not be around to post again.

  • Condition of battery? Good sustainable charge under load? No spark could be bad wiring or in the distributor. See Bruces' tips, No's 13,37,38,60,66,67 . Tip #43 on how to jump start your 6-volt/positive ground system with a 12 volt car/truck battery. Front mount can get set 180 out but at first crank will bust the tangs and housing. Firing order is 1, 2, 4, 3 CCW. If battery checks good, you have something wired wrong. get a copy of JMOR's Wiring Pictograms and verify wiring is correct first. You said you "...went back out and put back on with new wires..." Why would need to jump start it if battery was good? May need to pull distributor and go thru on the bench with checks before mounting.

  • What's the voltage at the coil?

  • The battery was not good, that's why I had to jump it. I'm at work now Bruce, I'm going to break out the meter tomorrow and recheck everything. Just ran out of time before work today.

    You need a good battery in the tractor to power the ignition. A jumper battery only gets you power to the starter.

    Charge or replace the battery in the tractor.

  • Thanks Bruce, brain fart, I was thinking it as jumping someone's car. Forgetting the 6v vs 12v setup. I knew it had to be something foolish.
