Ford 2000 Ignition

A friend has a 1969 Ford 2000 3 cylinder tractor at his farm and is having problems he thinks are related to ignition. First off he wants to know if there is a separate resistor outside the coil and I do not see any in the manual wiring diagram. I guess that means the coil has its own resistance to provide point life.
He said he put some copper ignition wire on it with conventional spark plug connectors. He did not use the long insulators and rubber grommets like it came with. He feels the wire is high quality copper wire and wonders if you can obtain the long insulators and rubber grommets by themselves somewhere?
I wonder if his problems are related to misfiring due to dirty spark plug cavities or shorting of one of the terminals he used.
 
Hard to say. I have more then one tractor on the place that has the plug wire ends open to air and never have any problems out of them. As far as the problem being ignition that is easy to check by first making sure the spark is a good blue/white and will jump a 1/4 inch gap or more. If it does not have that try a hot wire from the battery ignition side to the ignition side of the coil and see if it has spark then. By doing that you know it is either in the distributor or the wiring if it is an ignition problem
 
The wire that provides power to the coil is a a resister wire.
It is 3 folds of wire taped together.
Near the solenoid there will be a bullet connector in that wire. From there forward is the resistor.
I like to use the original style spark plug boots to keep crud out of the deep spark plug holes. Without them it can be a major PIA to service the plugs when they get full of dust, etc.
If he thinks he has a short in the SP wires, go start it at night and look.
Shorts are easy to spot in the dark.
 
The 3 cylinder thousand series gassers originally had a "resistance wire", which was a section of the wire going from the key switch to the primary of the coil that was made of some sort of metal that had a small amount of resistance that was folded back and forth over itself multiple times and covered with an insulator so the section of the wire with the resistorized wire inside of it is fatter than the rest of the wire and sort of looks like a fusible link.

Whether that particular 2000 has the original resistance wire, you would have to look to see. Some are still there, but a good number have been removed over the years and either the resistance wire was replaced by a ceramic ballast resistor, or the coil was replaced with one that needs no external resistor.
 
Thanks for the dope on the resistance wire......my friend did indeed replace that wire with a plain wire some time back! He did not know what it was and will now fix that either with a resistor or the correct wire............You guys on this board are a big help....Thanks again.
