Larry:

You will not hurt the points by letting 12V go to them-and the resistor would not change the voltage anyway-when the points were open, they would still see 12V.

Folks,  I got looked and the points are bad.  I thought I had the correct set but not, so I need to run to the Case-IH dealer to see if they have them.

I noticed there is no ballast resister before the coil.  I have had the tractor probably 8 or 9 years and it has ran fine. I suppose the coil could have an internal resister but the coil has been painted over so I cannot tell what it is. 

I assume for a 6 volt coil, one needs a ballast resister before it.

I do not know if the coil is bad or not. The points certainly are. 

For a 12 volt coil, does it need a ballast resister after it so 12 volts to not go to the points and burn them up?

Thanks 

Larry
