There were basically two different charging systems used (manual Low/High on light switch or Voltage Regulator) and on different years and models two different Voltage Regulators (3 or 4 terminal).
1) Manual light switch Low/High charge control that used a Cutout Relay instead of a Voltage Regulator. Gennys FLD wired to light switch
2) Automatic charge control that used a Voltage Regulator (NOT just cutout relay) and the light switch controlled the lights only not the charging.
3) Voltage Regulators used were 3 terminal BAT GEN/ARM FLD in which case loads like lights and Ignition were fed off the ammeter
4) Voltage Regulators used were 4 terminal BAT FLD LOAD GEN/ARM in which case loads like lights and ignition were fed off the VR's 4th LOAD terminal instead of ammeter
A) If it uses a 3 terminal Voltage Regulator
BAT on VR to load side of ammeter GEN/ARM on VR to Gennys ARM post FLD on VR to gennys FLD post THE GENNYS FLD DOES NOT WIRE TO LIGHT SWITCH
B) If it uses a 4 terminal Voltage Regulator
BAT on VR to load side of ammeter GEN/ARM on VR to gennys ARM post FLD on VR to Gennys FLD post LOAD on VR to light/ignition switch THE GENNYS FLD DOES NOT WIRE TO LIGHT SWITCH
c) Manual light switch Low/High and CutoutRelay
BAT on Cutout Relay to ammeter GEN on Cutout Relay to Gennys ARM post FLD on Genny up to Low/High Light switch
See Diagram for a 1947 B for a Light Switch Low/High manual charge control and cutout relay NOT a Voltage Regulator. Its possible to convert from a cutout relay and light switch to a VR as described above but in that case do not wire FLD to light switch but to VR instead.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
