Can do sir,,,,,,Okay iffffffff you have that external series ballast resistor YOU CAN BY PASS JUMP AROUND IT WHEN STARTING/CRANKING, WHICH GIVES YOU MORE SPARK ENERGY at the crucial starting time because the high current draw of the starter motor reduces battery voltage and spark energy. When the temp is cold the battery efficiency is greatly reduced PLUS the starter draws much higher current thereby reducing battery voltage causing a very weak spark when its needed the most in the straight unballasted 12 volt coil situations.....
If the 6 volt coil with external ballast is used, you can run a wire off a starter switch or solenoid etc to supply unballasted voltage to the coil ONLY while cranking, but then when running it goes back to the ballasted or 6 volts for a 6 volt coil as its designed. You cant use 12 volts on a 6 volt coil, she would overheat so the external ballast drops 6 volts leaving only 6 on the coil, buttttttt you can apply higher voltage for a short time like while shes cranking to make up for the reduced battery voltage
Some say they start on 12 volts and run on 6 although thats not exactly right since the battery voltage drops some while youre cranking.
BUT IF THERES NO EXTERNAL BALLAST RESISTOR (you use a 12 volt coil) its not laying there in the open avaialble to be by passed like a 6 volt coil with an external ballast can be.
OKAY if you have a 12 volt tractor but use that voltage dropping resistor ahead of and before the coil IT DROPS 6 VOLTS LEAVING 6 ON THE 6 VOLT COIL SAME AS IF IT WERE ON A 6 VOLT TRACTOR. It sees the same voltage and current as a 6 volt coil on a 6 volt tractor AND YOU GET THe SAME POWER AND SPARK ENERGY

Today's Featured Article - An AC Model M Crawler - by Anthony West. Neil Atkins is a man in his late thirties, a mild and patient character who talks fondly of his farming heritage. He farms around a hundred and fifty acres of arable land, in a village called Southam, located just outside Leamington Spa in Warwickshire. The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
