Ignition Coil Resistor for Ford tractors - Click More Info to view applicationsCritical Notes:
If you are upgrading from 6V to 12V and retain the original 6V coil, you must use this resistor in the wire between the ignition switch and the ignition coil.
This resistor will reduce 12V to 6V and protect the ignition points and 6V coil from burn out.
