Green Machine Lawn mower battery keeps dying
If your Green Machine lawn mower battery keeps dying, start with the battery itself because a dead cell is the most common reason a lawn mower battery drains or will not stay charged. Try charging it with a charger first. If it still will not hold a charge, the battery is likely bad and should be replaced. If the battery tests good, move to the charger and verify it is putting out the proper voltage with a multimeter, and make sure the outlet has power and has not tripped a breaker. On mowers that charge while running, a riding lawn mower charging problem can also come from a weak alternator or a failed voltage regulator, both of which can leave the battery undercharged and cause the mower battery not charging symptom to keep coming back. Checking these parts in order is the fastest way to pin down why your riding mower battery will not stay charged. Enter your Green Machine model number on RepairClinic.com to find the exact battery, charger, alternator, voltage regulator, or other replacement part that fits your specific lawn mower.

02 - Green Machine Charger
To determine if the charger is defective, use a multimeter to test the charger for proper voltage output. In addition, test the outlet used by the charger, and ensure that the outlet has not tripped a breaker.
Highly Likely
03 - Green Machine Alternator
The alternator provides voltage to the lawn mower while the engine is running and also recharges the battery. To determine if the alternator is defective, use a multimeter to test the alternator voltage output according to the wiring diagram.
Highly Likely
04 - Green Machine Voltage Regulator
While the engine is running, the voltage regulator sends the proper amount of voltage from the alternator to the battery to keep the battery charged. If the voltage regulator is defective, the battery won't receive enough voltage, causing the battery to drain quickly.
Highly Likely
