I bought a really nice John Deere H that hadn't ran since parked inside 20 years ago. It had no spark, so I checked and cleaned the points. Still no spark. I removed the coil and attempted to test the primary and secondary resistance. My information tells me the primary should measure 4.6 ohms and secondary should test 5000 ohms. Here's were my confusion starts. When I check from the spark poll to the ground lead of the primary I amazingly enough get 4.6 ohms. When I check from the spark poll to the secondary wire that connects to the points, I get the same 4.6 ohms???? Additional, when I check across the both primary lead and secondary lead I get a direct short or continuity. Should I get a connection across the two leads? Why am I getting the same 4.6 across the secondary?
