I'll take a shot but you would be better informed by studying a service manual for your tractor. The voltage regulator (or current regulateor would be a more descriptive term since it regulates more than mere voltage) is used to connect the generator in the charging system whenever there is a demand for current. The current may operate the accessories or recharge the battery. When the battery is fully charged and there is no demand from accessories, the current regulator disconnects the generator from the system. The current regulator does this connect/disconnect task at levels where voltage and amperage will not rise to the point of damaging accessories or battery. When you mention "spark", I think of the ignition system. The spark to the plugs is supplied by the distributor and ignition coil as your battey powers your starter to turn the engine. If your battery is operating your starter, then you should get a spark regardless of whether your charging system is working. As for the three posts on the current regulator, the "F" (field) terminal connects to the "F" terminal of the generator, the "G" terminal connects to the "A" (armature) terminal of the genrator, and the "L" (load) terminal connects to the "BAT" (battery) terminal of the ignition and starting switch. This is a normal hook up but as mentioned if you consult a service manual for your tractor, the information will be more specific for your tractor.
