ces, you state "I've read that when a 12v conversion is done, the 6v coil isn't replaced for easier starts"
That can be true PROVIDED you add a series voltage dropping (12 to 6) external ballast resistor plus install/use a start ballast by pass system.
You cant simply use a 6 volt coil on a 12 volt tractor to achieve "easier starts" unless you add the external series voltage dropping resistor (or points burn prematurely and coil overheat) and to get those so called "easier starts" you have to install/use a by pass system that by passes the ballast while she's cranking so the coil gets unballasted battery voltage during that time.
So on a 12 volt tractor you can use EITHER a full true 12 volt coil OR ELSE a 6 volt coil plus a series voltage dropping (12 to 6) ballast. And if you want to improve cold weather starting you could use a 6 volt coil plus ballast BUT add a ballast while cranking by pass system.

Today's Featured Article - Women and Tractors, A Woman's Touch - by Teri Burkholder. I thought I would give you a little background on how I got myself hooked on tractors and their restoration. My family is a very "crafty" bunch of people. By crafty I mean good with crafts!! My Dad is a retired industrial engineer from Bucyrus Erie which made big shovels for excavating and he is also a wonderful wood worker. My mom and my "guardian angel" has had her own ceramic shop for 30 years and is an excellent painter. With these skills always active in our house it was hard not t
