Thanks Gene and John for your help. I now know how to time the mag. I putit together and put it back in the plane but could get no spark. I amwondering if the new coil is defective. I think it is the correct coil.(Gene, the mag # is10-51360-26. The coil came from Aircraft Spruce and is #10-357164-1). Thecoil has two leads, a long one and a short one, one coming from each side,which I think are the same wire since there is continuity between them. Thecatalog says "furnished with long and short coil to points leads. It has asquare metal bar sticking out of each end that clamps to the mag housing andit has a little brass tab in the center of the coil that the distributorcontact pushes against. My questions are, what do I put my ohmmeter leadsagainst to test the primary and secondary resistances, and what valuesshould I expect. I don't seem to get what Gene suggested, but I may bemeasuring incorrectly. If the coil checks out, is it possible to "benchtest" the mag? The point open and close. I am sure I connected the "pointslead "correctly, ie., to the same place the capacitor connects. Could a badcapacitor cause the mag not to work at all, or does it just cause the pointsto burn. Points look good, by the way, and the old coil was definitely inbad shape, leaking resin and cracked. What else could be wrong. Thanks foryour help. Joe Kohler. Very frustrating, but what else is new. Its all aneducation, isn't it. Hey, my kid just spent about 3 hrs trying to figurewhy the new print cartridge didn't print blue, put in the old one and gotblue. Go figure.________________________________________________________________________________
