Chuck..... ...do you always read 12 volts at the coil? Points open? Points closed? My bet is you have a 6 volt coil, that requires about 3.5 volts (2.5 min, 4.0 max). The reason I think it is a 6 volt coil is 2 fold, 1) you have to argue with your part person that there is such a thing as a 12 volt coil and 2) most parts emporiums don't carry a 12 volt frontmount coil anyways. Real 12 volts on a 6 volt coil will fry it toote-sweete. (probably less than a minute). And no, I don't know of any eazy shadetree mechanic check for a bad ignition coil except by replacement. Well, yeah, you could check the primary for continuity with a ohm meter off the tractor, but that will only prove the primary winding is continious or not. If it is not continious, then obviously it is bad, otherwize, ya still don't know. I suggest that you make up your mind that your ignition coil is bad, (not what you wanted to hear, I'm sure) decide which kind of coil scheme you want and start over and do it right this time. ..... ...Dell
