Ford 9N ignition question.
Years ago my neighbor and I bought a 9N tractor together. we used the
tractor for many years and then for various reasons we parked it for several years. Deciding to use it again I wasn't able to get any spark, even though it worked fine when we parked it. After cleaning the points I was able to confirm that the points were properly adjusted and making contact. Opening and closing the points by hand resulted in an erratic and weak spark. Tracing the really simple electrics I found that the power from the battery goes through a ballast resistor. Unlike cars and other vehicles with ballast resistors that I'm familiar with the ballast resistor is bypassed during starting. But the old Ford 9N tractor doesn't do this. I ended up connecting the coil directly to the battery and this resulted in a pretty good spark. Good enough that the tractor started right up. So why the ballast resistor? Why would the current need to be limited for regular operation if the ballast resistor isn't bypassed during starting? Anyway, I am not going to run the tractor with the ballast resistor out of the circuit because It is supposed to be there. And before it was parked for several years it worked just fine. I think the reason for the poor spark must be corroded connections somewhere in the ignition circuit. But I'm still wondering why they designed the ignition circuit with a ballast resistor. Anybody know? Thanks, Eric |

On Monday, April 24, 2017 at 4:34:08 PM UTC-4, But I'm still wondering why they designed the
ignition circuit with a ballast resistor. Anybody know? Thanks, Eric The total resistance is the wiring, the ballast resister , and the resistance of the coil primary. If all the resistance was zero, the current would initially be controlled by the inductance of the coil, but would be high and burn the points. Some coil essentially have a built in ballast resistor and do not need or use an external ballast resistor. When you are starting the engine the voltage is lower. So if you short out the ballast resistor it is closer to how it is when the engine is running. So even with the lower voltage when starting , you get a good spark. Dan |

Dan I know about the shorting Dan, read my post that you replied to a little more carefully. I wanted to know why the ballast is there when it is never bypassed. dbp sent me a link and now I understand. Eric |

But I'm still wondering why they designed the ignition circuit with a ballast resistor. Anybody know? Thanks, Eric Forgot to say that the weak spark might be caused by a bad condenser. THe condenser helps keep the spark from occurring across the points instead of at the spark plug I've got no familiarity with what a condenser is (outside of HVAC) in car circuitry. But thanks for saying what it does. It is actually a Capacitor. A rose by any other name - - - Its just that a condenser also refers to the hot, liquid, high pressure 'low side" of a vehicle's air conditioning system. Its not always a good idea to have two different auto parts with the same name. They've got to do something about "wheel," then. g I haven't heard "condenser" for "capacitor" for a long time. I'll have to look at my really old engine books to see when it last showed up. Then there's two different fenders, and two different hoods, dpending where you are in the world. https://electronics.stackexchange.co...ays-of-electro "Not that anyone cares, but "condenser" seems to have faded from use from the mid 1930s through about 1950. Dubilier was using capacitor by 1940 but Allied catalogs didn't switch to capacitor until around 1950." I recall my ham radio mentor, and others using the term back in the late 1960s. And of course..car mechanics even today. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Any vehicle w/ a distributor/points system...auto parts lookup is still the common name (at least in US; don't know for certain what the Brits used). Not sure when production in US finally would have ceased, trucks were exempt from some of the more onerous emissions reqm'ts for a while after automobiles so therein is probably where the last would have been. Off-road equipment, of course, lasted for quite a lot longer. Condensers are still quite commonly found on vehicles on the roads in this side of the US. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |
