Would like to know what the voltage is after the ignition resistor to the ignition coil. What is the purpose of this resistor.Also is the voltage regulator adjustable. I would like to use an 8 volt battery and increase the output of the reg.If this cant be done I would like to convert to 12 volt but still need to know the size of the resitor to supply the correct voltage to ignition coil.

The voltage on the front mounted coil with the points closed should be around 3.5 volts. Of course the battery voltage would appear if the points were open. Employing an 8 volt battery, is more trouble than it is worth. The voltage regulator could be adjusted with a lot of trial and error. A lot of tractors including mine remain 6 volts and start and operate just fine. Mine starts on the second turn of the starter. Most people change to a 12 volt system for the wrong reason. A 12 volt system is more fault tolerant than a 6. If a 6 volt system is kept in good order, it functions well. The only reason I have ever heard of that could justify changing to 12 volts, is that someone wanted to use his/her battery for running a sprayer... 6 volt systems can also be jumped from a 12 volt battery, provided it is done correctly. That is an other subject.

Yup, true, but..... When you need to go jump start something else with the tractor, it sure is handy to have 12 volts! Usually around here batteries go dead in the middle of snowbanks, mudholes, and other places the 2N is real adept at reaching. Maybe I need to put a set of tractor tires on my pickup truck. But that's another story.. ;0)

I don't work for Sam Walton (of Wal-mart/Sam's Club fame) but I gotta let you know about a product I picked up at Sam's Club that I am thorougly happy about. It's a Jumper box. About the size of a lunch box (maybe a little bigger) with 2 jumper leads coming out (red & black). Cost about $50. I have one in the trunk of every car I own. Very portable and works better than jumping from another vehicle (my experience). We use them at the credit union to start our sorry collection of junk repos. Easier to store in a trunk that a set of cables.

Ok.. I knew that I would get a skillet whomping on this... but hey... people can make up all kinds of excuses... I don't remember the last time I had to jump start anything... Batteries usually (Usually being the operative word here.) give you advance notice that they are about to take a crap...Most of the time the simptoms are ignored... and or not understood...

I agree Claus, my 9N starts on 6V after a few cranks and some choke on a 7 year old tune up. I know I should probably check points and plugs and such again but I'm half afraid to mess with it 'cause she runs so good.

Agree, to some point.. The old adage, Don't fix it if it aint broke... However, we must temper it with preventative maintenance... so that when we need it that it "Aint broke."
