Roy 0 Posted June 29, 2010 From the S/G to the regulator the wires should go: F (field) to F, A to A (armature) or G (generator) Small wire from the battery should go to the B terminal on the regulator. Large cable/wire from the starter push button should go on the S/GA or G terminal. The regulator L terminal is for lights if you have them. Sometimes there is a jumper wire from the regulator frame to the tractor engine or frame. Hope this helps. Edit: Link with wiring diagram by RayS added.
