Terry, yep I have an idea of what that L terminal is for::::::
The L (Loads) terminal is where Loads like lights and ignition are served voltage from usually via it being wired to the BAT input terminal on their switch(es). With 3 terminal Voltage Regulators that only had BAT ARM FLD but no L terminal, those loads would have been served instead from the Load (NOT battery/starter) side of the ammeter. If youre converting from a 3 to a 4 terminal VR with the L terminal, unhook the wire off the ammeter that went to the BAT input terminal on switches (lights and/or Ignition) and feed the switches BAT input terminal instead by a wire up from the VR's L terminal. The lights n a coil ignition would still work if you ignored the VR's L terminal and kept them fed from the ammeter, but you may as well use n get the full benefit that 4 terminal VR has to offer since you already have it. Id Polarize the genny once things are wired up but before you start the tractor.
If you converetd from 6 to 12 volts there are other issues I trust you also took care of such as a 12 volt coil or a ballast resistor if its a coil ignition and light bulbs etc.
