i have a restored jd 112 with a 10hp techumseh SSI engine that has no spark and i cant figure it out ive ruled out the coil and the ground to the coil anyother suggestions will be highly appreciated Thank you Nathan N.:thanku:
Points and condensor would be my guess on it. Check to see if the points are opening and gapped properly. Also check that your condensor has a good ground and the wire is in good shape. It's amazing how much trouble that little thing will cause!
I am a little late to reply here, but the SSI unit is probably dead. Here is a link to the write up I did on a HH120 motor. This is the best way to fix this in the long run. A new coil is stupid expensive, used, and may fail.
Keep in mind, the SSI is a two part system. There is a charge coil on the stator coil that can fail and not charge the SSI as well. The conversion removes that part as well.
BTW, when you send the SSI coil (and if you like, the stator coil) to him, he will test the parts. Stator coils are easy to buy on e-bay and if your SSI is ok, you may be able to replace just that. Ed has a test set up to make sure that the coil is bad before he convertes them. On mine, it did have spark for a while and then would die. This was shown when Ed did a long term test to see if the spark held up. :fing32:
I think he charged me $25 to test and convert the coil, and if you go to a junk yard, you may gain all the parts and a wire harness for about $25.00 Grab as much harness going to the ingition block as you can, it will give you a factory plug and should be enough to connect the ends directly where they are needed. :fing32:
Shoot, I completely forgot about this thread. Do you still need help with it?
Also you could wander over to www.weekendfreedommachines.com and take advantage of the vast John Deere knowledge there, it's a JD only site. Lots of experienced folks there too. There's also a classifieds section/parts wanted that can help you find parts if need be at good prices.
