Hey all,
I have an electrical issue and I am looking for some thoughts on a potential cure. Any ideas would be much appreciated.
I have a 1948 8N with front mount dizzy. Mid-summer it began to have intermittent periods of hard chugging, sputter sputter, dead.
Then the next time I would go to use it, it would be fine. It runs my mott mower, so it needs to run well to drive it properly. I cleaned out carb, cleaned plugs, etc, and it seemed to be okay until now. I proceeded to replace the points, condenser, and rotor. I could get it to spark, but seemed intermittent and weak.
As my battery got tired of cranking, I decided to boost with 12 volts, and the tractor started right up. As soon as I take the lead off the 12 volts, the tractor starts to sputter. I can get it to idle on 6 volts, but wont let me rev up. Im thinking there must be some sort of a short somewhere or drain somewhere, but I cant figure out where to look. Rebuilding the distributor didn?t help, plugs are clean, electrical system I redid last year. I swapped coils with my other 8N and no change. I sanded the points in the voltage regulator, and it is charging. I have tried disconnecting the genny, regulator, etc, still nothing. Everything checks out fine, but spark is still weak, and im running out of ideas. 6 volt battery cranks the engine fine, so connection is good. This week I will probably replace plugs just to be safe, and try swapping dist. Cap. Other than that? I have no ideas.
Thanks to any and all words of wisdom.
