1952 8N Electrical Short

New User
I have a 1952 8N that has been converted to 12 volt. I apparently have an electrical short. I have been told it could be this part but I cannot find the name of it to order a new one. This part gets very hot when connected to the battery, will get burned if touch it. I did find a bare spot on a wire and fixed that but dead short still there. I have used this site quite alot but new to the forums. Thanks in advance from Georgia.
 
iieasy........thats a 12-to-6 volt converting resistor. Thats an el-cheapo bubba trick. Byte the bullet and use a REAL 12-volt round can sparkie coil IC-14SB. $20 from NAPA. NO resistor necesary........HTH, the amazed Dell
 
Assuming you're talking about a resistor, see tip # 30. As Dell said, most folks use a 12v coil w/o an external resistor.

You can safely start & run the tractor w/o the resistor for some time before the current heats up your 6v coil, so just jump the resistor & see what happens.

Also, Google "wiring diagrams JMOR" and fined the diagram that fits your tractor.

I'm trying to post your picture for you. That is not a standard
resistor for any N tractor that I know of. Farmer-ization.

I agree with Dell though. Get a true 12V coil and ditch the
resistors. Assuming your tractor is a side mount distributor.

thx. it is a side mounted distributor. 12v. I have done away with the points and put electronic ignition on it but didnt replace coil. I am assuming when I install the coil that Dell mentioned I will just do away with this resistor. Cant remember off the top of my head but seems like the wire to this resistor goes to the switch and top of coil. Will check tomorrow.
 
I have the same identical resistor on my 48 front mount which has been converted to 12v with the one wire alternator. It was converted before I bought it.
QUESTION.... Please explain to a novice (me) just what I need to do to eliminate this resistor on a front distributer with the coil on top.
 
The points and coil will handle the increased current caused by jumping the resistor. But, will that increased current say "bye-bye" to his electronic ignition module?

The electronic ignition actually called for a "hotter" coil so im not sure since removing resister.
 
I believe Pertronix would produce a "hotter" coil by increasing the number of turns in the secondary, thus giving a higher step up voltage. They still offer these coils with a 1 1/2 or 3 ohm primary to retain desired input current.
 
" I have done away with the points and put electronic ignition on it but didnt replace coil."

That's a very important piece of information.

Call Pertronix and ask them what should the internal resistance be for the proper coil to use w/ your specific EI unit. Chances are it's 3.25 ohms. If it is, then buy the IC14SB coil from NAPA and eliminate the in-line resistor.

And you will need suppression plug wires or you will burn up the EI module.

If it is working, leave it alone. If you are having problems with it you could remove it and install a resistor like one this site sells or you could remove it and install a 12 volt coil.
 
Player........pay attention. The weird 4-nipple front mount is 6-volt ONLY. You will need not only the 12-to-6 volt converting resistor...but...ALSO the infamous ballast resistor. You kenn count nipples, kent you? ........respectfully, nipples Dell

Make sure your original ballast resistor is wired in like it should
be. It's the one on the back of the dash panel that also serves
as the wiring connection spot. Then replace the coil with a 12V
coil. Our hosts sell them [b:c6b542d500]here.[/b:c6b542d500]
 
He's got a 52 8N with side mount distributor. It had no original ballast resistor and round can coil. Side mount 8N had a 2 post wiring terminal
 
Scratch this. I was on Classic View and it linked your reply under original post. Modern view shows it in answer to Copperhead, when referenced to his question your answer is correct.
 
"He's got a 52 8N with side mount distributor."

My reply was to Copperhead who asked how to wire his front mount.
Kind of hard to tell who replies to who sometimes.
