Yard-Man Lawn mower battery keeps dying
If your Yard-Man lawn mower battery keeps dying, start with the battery itself. A battery with one or more dead cells may charge briefly but still will not stay charged, which is the most common reason for a riding mower battery will not stay charged or a mower battery not charging complaint. If the battery tests bad or will not hold a charge after using a charger, replace it. Next, check the charger and the wall outlet with a multimeter to make sure the charger is putting out the proper voltage and the outlet has power. If the charger is fine, move on to the charging system. A weak alternator can cause a lawn mower battery drains problem by failing to recharge the battery while the engine is running, and a bad voltage regulator can keep the correct charging voltage from reaching the battery. Testing alternator output and regulator function against the wiring diagram will usually pinpoint the fault.

02 - Yard-Man Lawn Mower 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 - Yard-Man Lawn Mower 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 - Yard-Man Lawn Mower 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.
