My Farmall A was converted to a negative ground 12-volt system more than a decade ago. The alternator is an "American" brand with a voltage regulator (I,A,S,F) installed next to it. Originally, a key ignition switch existed, but eventually, an underrated 3 amp push starter switch was spliced into the system and an on/off switch linked to the magneto is used to "ground" or kill the engine after use. I have replaced the faulty 3 amp push starter switch with a heavier duty weather-proof push starter switch using the same hole from the old key ignition switch. I also bought a new 12 volt battery to replace the old battery with a bad cell. My new problem is that I"m getting some minor smoke from the "field" wire to the voltage regulator when the battery is hooked up and you hear the regulator polarize. Do I have the wiring to the regulator plugged wrong or is there a short with the orange "field" wire? It looks a bit frayed, so I have electrical tape wrapped around it, but I still need to know why I"m getting some residual smoke from the regulator. You have to look at it real close to notice. I need a wiring diagram for a 12 volt conversion kit on a Farmall A if anyone has one. The brand name of the alternator is called American. Is anyone familiar with this brandname? I"m told this brand was used on many Ford products. Is that true? Please help me troubleshoot my electical problem so I can start mowing with the Farmall A, again. Also, how can I shut off the battery without having to take the ground cable off all the time? Shouldn"t battery power only be used when I activate the new push starter switch for the starter? Otherwise, the alternator should keep things charged and I should only be using my MAGNETO to kill or ground the tractor when I"m done with it, right? Please help.

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
