Thank You and Hello Ben, I am sorry if I did not say it correctly in my original post, I don't think I blew any condensers, I just do not know how many micro Farads it should be. I tried a few different ones, because being in the industrial electronic business, that is one thing I have quite a few values of. Bill - USN Ret, was kind enough to tell me to check with you, however, me being new to this, I did not know how to find you, thank you for finding me! I am not even 100% sure my coil is bad, unfortunately, I probably won't have time to get back to it until this weekend. I learned from an old listing on ebay, from Joes outdoor power, that Massey Ferguson used this same coil and iron piece that bolts on behind the engine shroud. The info listed said it was from a model MF10, MPN 1446, dated 1968, engine being a HH100, engine Spec # 115033, with the engine serial # 6031. The picture he had on the listing looked exactly like mine, however the listing expired. If I had an e-mail address for you, I could send you pictures of what I have, if you would need it. The actual Iron part of mine comes apart, by removing one screw, making the coil itself replaceable. I would like to know more about joining your test group, as it will not take me long to find out and let you know. I actually took the iron apart, so I could measure the inside dimensions of what the coil has to be to slip on. It measured .008 to .010 over 1/2 inch on the square part and 1.5 inches on the length. I am pretty sure the condenser is a Tecumseh part # 32015 from the research I did so far. I saw you have one listed and figure I might as well order one also, because I am not sure the .25 mF I measured on mine is what it should be. I would think it to be original to the engine, but that would make it about 45 years old. If you could leave me know more about test group, maybe that would be the best way for me to go. My e-mail address for my work firstname.lastname@example.org and I am usually on that most of the day. Again, thank you to everyone helping me here.
