Murray Lawn mower battery keeps dying
If your Murray lawn mower battery keeps dying, start with the battery itself. A battery with one or more dead cells may take a charge from a charger but still fail to hold it, which is the most common reason for a riding mower battery will not stay charged. Next, check the charger and the wall outlet with a multimeter to make sure the battery is actually getting proper voltage during charging. If the battery and charger test good, move on to the alternator, which should supply voltage while the engine is running and recharge the battery at the same time. A weak or failed alternator is a common mower battery not charging problem. After that, test the voltage regulator, since it controls how much charging voltage reaches the battery. If the regulator is bad, the battery can drain quickly even when the engine runs normally. Whether your lawn mower battery drains overnight or you are dealing with a full riding lawn mower charging problem, entering your Murray model number on RepairClinic.com will help you find the exact replacement battery, charger, alternator, or voltage regulator for your mower.

02 - Murray 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 - Murray 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 - Murray 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.
