iīm new here and found this forum when browsing for help with a non-sparking magneto. I live in sweden and there are a lot fewer people to ask about old catīs overhere.
I have a cat d4 that runs great if you pull it to start with a wheelloader but the pony engine doesnīt work. The problem is the magneto who donīt give any sparks. I have tried it on the workbench with a drilling machine and i get sparkīs at 2000 rpm but not below. I have measured the resitance i the coil and itīs about 7,2 kohm. What could be wrong?
