David, if youre at POSITIVE GROUND, the coils + becomes the "to distributor/ground" while its - is what receives power from the ignition switch i.e. "to switch" The dealer is "wrong as rain" on the coil, however. Heres the deal, if its a 12 volt system, you can use a 6 volt coil simply by adding an external voltage dropping (12 to 6) series Ballast Resistor ahead of the coil after the ignition switch. However, if its a 6 volt tractor, the coil dont somehow automatically mysteriously change and if youre using a 12 volt coil it will still produce some spark, but not as good as if you used the correct 6 volt coil. A coil is more of a current device then a voltage device and regardless if a 6 or 12 volt unit, it runs and switches about 4 amps of current through its primary winding. To do that, A 6 volt coil has about 1.25 to 2 ohms primary resistance while a 12 volt has more like 2.5 to over 3 ohms. Therefore if you use a 12 volt coil at 6 volts, youre only running about half the normal amps through it as required for a good hot spark. My guess is the spark would be more of a light wimpy yellow then a good hot blue spark under such use. My advice if youre at 6 volts GET A 6 VOLT COIL. Myself n Texas Denny n Bob have a hot friendly discussion over on the AC board about coils, go read that if you wanna get cornfused n bored lol Good Luck n God Bless John T Nordhoff in Indiana, retired electrical engineer

It is also very apparent that these folks are getting a lot of very poor and often very dangerous advice fro
