Hey guys...long time lurker first time poster-
I'm working on my neighbor's 9n 12 volt tractor, I'm mechanical but when it comes to electric I know the basics only.
Here's what happened= Tractor ran fine while discing a pasture and suddenly died out of nowhere as if the key was turned off. Tractor
would not even crank after and neighbor let it sit and bought a new tractor. A couple months go by and he asks if I want to tinker with it
and fix it and we would split the money when sold.
So first I simply cleaned the battery terminals and charged it up and it now cranks like a champ but still no fire. I then found a large
crack on the hidden side of the coil and thought great that could be it....so I ordered a new coil and resistor and still no fire. I opened
the distributor cap and see 2 contact points are very gouged and the other 2 are covered in carbon. So I ordered a new cap and rotor and
still no spark coming out of the distributor cap to plug wires.
I started with my light up wire tester going down the line from the battery to the distributor, have power all the way to points and shaft
of distributor and it went on and off when the points open and close.
The rotor does not light up my tester but i'm not sure if it should? When testing the cap I spin the shaft and when the rotor spins I get
no spark at any of the 4 positions.
I checked the resistance of the coil and at the bottom spring it is low and on the tab that sits on the distributor cap it is much higher
but both the new and old coil test the same so I'm not sure if that is right or maybe I got a bad new coil?
I hope this makes some sense and I can add more info from yall's questions. Pretty much seems I get power to the distributor but can't get
it to the cap and to the plug wires. Any help is much appreciated!
