Another Electrical Question for the Experts

How many wires come out of the generator?

If there's only one and it runs to the "voltage regulator" and then on to the battery, you've got a third-brush generator that needs adjusting. If this is the case, there should be an adjustment mechanism someplace on the generator.

If there's more than one wire out of the generator then you've got something else and we need to know what year, make and model of tractor you have since you say it's a stock system. Then someone familiar with that tractor can probably tell you exactly what to do with it.

Most likely, the problem is that the generator is putting out too much power. It should have an adjustment mechanism for the position of the third-brush. This is the only thing that controls the output of the generator.

On N's, I usually tell people to adjust the screw so that they get three or four amps of charge into the battery. This is a compromise between keeping the battery charged and not overcharging it.

Both sides of the ammeter are live! one side comes from the Battery as you describe and the other is metered through the ammeter.

What does the Ammeter "Say" when Ignition is OFF
If you show current flowing your Reg (CUTOUT) may
be backwards Does the Charging Voltage/Current go down when you adjust the 3rd brush

Hope this helps

The Output is feed to the "cutout" relay that connects or disconnects the feed to the battery. (Normally Connects when Gen exceeds Bat voltage)

Your electronic one (cutout) should ALSO detect Bat Voltage and disconnect at a (its) designed Voltage.
