With the wires removed a 6 volt coils primary resistance between its lil + and - terminals is around 1.25 to 1.75 ohms while a 12 volt is more like 2.5 to 3.5 ohms. It bear any label or writing??? You dont need a ballast if its a full true 12 volt coil. Id guess (depends on oil or residue) it may smoke less then a minute till its all burned off then stop??? Id have it well bonded (metal mounting clip) to a piece of heavy metal to help heat sink it. With the ignition on not running and points closed its drawing around 4 amps and at 6 volts, thats 24 watts butttttttt if running theres some duty cycle reduction taking place you know. Its not god to just let it sit there n cook, turn her on n fire her up maybe???? This assumes its a true ignition ballast of 1.25 to 1.85 ohms rated somewhere over 25 watts?????????? If its only a 5 watt resistor it will fryyyyyyyyyyy John T
