the "little wire from the light switch fuse" should go to the negative ampmeter terminal. the positive side goes to the starter wire which is connected to the negative side of the battery. if you connect the "small wire" from the light switch fuse to the positive side of the ampmeter you have taken the ampmeter out of service and it will not read anything. this does not explain why the battery does not charge.
--if the generator is good and the cutout is new, why wont it charge? check like this.
1. make sure the ampmeter is in the circuit right.
2.take the "A" wire from generator termnal to the cutout, and touch on the other side of the cutout(bypass cutout) now does it charge? if so then the cutout is not closing in.
3. take the "F" wire off the generator and ground it to the tractor frame, this bypasses the light switch and its ground wire? if it charges now, the light switch is bad or not grounded.
--who do you know the generator is good? if it is, i would guess the light switch is not grounded or the resistor inside is bad.
---the cutout is normally open. it will only close when the generator puts out 7 volts and is pushing toward the battery, so a bad ground on the light switch will make the cutout malfunction. when you shut down the motor, the generator voltage drops and the 6 volt battery voltage runs backward and the cutout then opens to stop the flow of current to discharge.
