My 12V front mount 9N had no spark. The points are new, and gap checked. The coil is 2.5 ohms. I checked out the distributor and coil for operation and continuity, following the advice in the archives. All tested fine. Coil pigtail spring makes good contact. However, the only way I could see to check the coil-tab connection to the contact on the top of cap was with a continuity tester while pressing the cap and coil in together in my hands (with gasket in place) while having one lead touching the tab and the other lead on the center of cap. I can see the coil-tab deflect slightly when putting the coil on the cap, but continuity seemed intermittent. Maybe my hands weren’t so steady. To be sure I had continuity, I took the copper strip from old set of points and wrapped it around coil-tab to act as shim/bias spring. This helped get regular continuity with the hand held test. After re-installing the distributor and coil, I checked spark (on No. 4)-- now it did have spark (even if a bit on the yellow side). It then started right up, and ran for about 5 seconds, then cut out. I re-checked for spark (on No. 4 again), and it had no spark again. I’m gonna need it to run for more than 5 seconds at a time to get the hay cut. Any suggestions where I might be going wrong?

I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
