8N won't start

I've been using this tractor around the farm for quite awhile. The starter went out. Decided it was a good time to have it overhauled anyway. When I first got it back, it ran, but was a bit touchy to start. One day, while pulling fence posts, it just quit. No power at first, and then it just stopped.

I've replaced starter switch, plugs, wires, distributor, coil and it still won't start. The coil keeps getting **really** hot, just from cranking the engine over. The tractor will turn over, but it won't fire. There is no spark from the coil.

Suggestion would be really appreciated.

Pat, The coil getting "really" hot would suggest that
the current is continuous, points not opening.

I would look for a short to ground on the wire
and terminals between the coil connection and the Points. Maybe a shorted condenser?

Need more info to be much help, 6v or 12v? front
or side mount Dist?

Good luck

You did not specify the voltage on your tractor and or whether it is a side mount or front mount distributor. Side mount distributors are easier to troubleshoot than front mounts since you can get at the wiring easier. Could be your coil is getting hot because it became a crispy critter. The best way to tell if a coil is bad, is to replace it. It is almost imposssible to determine if you have a shorted turn(s) with an ohm meter. You need to take a volt meter and check the primary wire to the coil. On a 6 volt coil, you should see about 3.5 volts with the points clolsed and the full battery voltage with the points open. If you have a side mount distributor you can remove the center coil lead and hold it about 3/16" away from a good ground and you should see sparks when turning the engine over... The best way to check the distributor on a front mount system is on the bench...but that is another story.
Good Luck
