A few things you can do: 1 – Make sure the wiring between the generator, cutout (or regulator), ammeter and ungrounded battery post is in good shape, all connections are all tight, etc. Also make sure the ammeter box and/or voltage regulator is solidly grounded. 2 – If the generator still has the stock cutout - ie. it has not been refitted with a voltage regulator - make sure you run the tractor with the light switch in the high charge, “H” position (2nd notch from the left). 3 – Adjust the generator’s 3rd brush to it's maximum output position. (Set it as close as possible to the nearest fixed brush) 4 – If the tractor has a voltage regulator, could be the regulator is limiting generator output too low. A new regulator is required. (A good regulator will allow 12 – 15 amps at full RPM until the battery becomes fully charged). --- Keep in mind that no matter what you do, the generator will not provide any current at low speed. If you do a lot of idle/low speed operation consider converting to a 6 or 12 volt alternator.
