Use of the resistor in conversion

Got a 12 v conversion kit which comes with a new resistor but do I need to put it in the coil to ammeter wire or leave off?
A few diagrams show put it between but mine doesn't have one to begin with. Should I put it between or leave out?
 
ASSUMING by your "handle" that you are a late 8N owner (with a "side-mount" distributor) you better take another look at the diagram, as there's NO "wire between the Ammeter and the coil".

If that's in fact what you are working with, and you are retaining the original 6 Volt coil, a resistor needs to be installed somewhere in the wire between the "switched" terminal on the ignition switch and the ignition coil.

Also, assuming you are changing the ground polarity from (+) to (-) you need to swap the wires between the two primary terminals on the coil to correct for the change in system grind polarity.
 
What tractor?? Your handle say 1952 8N which would be a side mount distributor but handles mean very little to what you have for a tractor. If in fact a 1952 8N Bob has you covered and yes you need the resister or a true 12 volt coil that says no ballast resister needed on it
 
I was thinking wrong.
The alternator goes to ammeter so I guess I need to put a 15 amp fuse in that line.
I have a 12v coil that states NO resistor needed.
I am working on a 1952 8N.
I need to remove the voltage regulator completely from what I'm reading.
 

The ground off the coil will still go to the distributor where it was won't it?
So with the 12v coil positive goes to ignition switch.
I think that's what I read.
 
If you have a resistor coil you shouldn't need it. If you are coverting it to 12 v alternator and it is positive ground now you will need to change it to negative ground and reverse wires on coil.
 
Ok - which resister are you talking about? The ignition ballast resister? It will be a large white porcelain object with two screw or spade terminals.

Or is there a small current limiting resister in the kit that might go in the alternator excite circuit? This would prevent the alternator from backfeeding the ignition circuit when you shut the key off. I quickly scanned the replies and didn't notice any mention of a current limiting resister.
 
If you are concerned about protecting the wiring from a short you can install one of these fusible links as show in the link. Not pushing this brand or store just one example that came up on Google. It should be installed where you are picking up positive battery power to connect the alternator to the battery and feed your ignition and lights from the protected side of it as well.

Large white one comes in the conversion kit.

Everything is hooked up by the diagram that comes with conversion kit but still have no spark.
Changed out points and condensor still no spark.
Thought about ground so took off ground strap from the battery to the frame and sanded down to bare metal but thinking I might have to change the ground strap to a covered cable style.
Also may change out ground wire from oil to distributor.
Anyone have any other ideas? Thanks
