dads 8n ford tractor burned out new coil after about 3 to 5 hours of running. Need help to figure out why.

it is 49 model front mount distrubitor, 12v conversion new plugs, wires, and was a new coil tractor was totally rewired. the coil is out because we put the old 6v coil on just to see if it would fire then it fired seemed like it wasnt firing fast enough but it was firing. put the 12v coil back on and it doesnt fire. need help figuring out why new coil burnt out after about 5 hours of running
thanks dale

Those so called 12 volt square coils are in fact a 6 volt coil and you need a ballast resister in the wire from the ignition switch to the coil or it will burn out very fast. Its also hard on the point and thats probably why it will not run with your so called 6 volt coil the points need cleaned or replaced. Gap on the points is 0.015 by the way

When converting to a 12V system, you need to have a real 12 V coil OR you must put a resistor in the primary circuit to limit the current to 4 amps max. Doubling the system voltage from 6V to 12 V will double the coil current and burn out the 6 volt coil unless you add a current limiting resistor.That Ford front mount is an odd ball system because I eblieve the coil is built in to the distribor cap or soemthing like that. Go to the 9N,2N,8N Forum because that's where you find the most experts on your model of tractor.
