The way to Examine the Alternator to a Craftsman Riding Lawn Mower

When the battery on your own Craftsman riding mower will not hold a charge, there may be a problem with the alternator, in contrast to the battery itself. The alternator provides electricity to the battery while the mower is running and recharges the battery as well. To learn whether the alternator is the culprit behind your problems, you may use a small, handheld machine called a multimeter to test the alternator and reach the base of the problem.

Set the knob on the multimeter to the DC AMPS setting to perform a test of the direct current emitting in the mower’s alternator. Check your owner’s manual to ascertain what the amp output of your model of mower ought to be. This information is in the item specifications section of the manual and also varies from model to model. If you don’t have a manual, call the Craftsman customer service line and provide the agent with your mower’s model number to acquire the amp output. You may also check the model number plate situated on each Craftsman mower for those amps.

Plug the black wire of the multimeter to the COM port. Connect the other end of the black wire to the positive terminal of the mower’s battery.

Plug the red wire of the multimeter to the AMPS port. Connect the other end of the red wire to the output of this Craftsman mower’s stator. The stator wires emerge from under the compressor housing.

Start the mower’s engine and let it operate at full throttle for many minutes. Check the readings of this multimeter to make certain they are as high or higher than the amps indicated in your user’s manual or on the mower’s item label. A considerably lower reading indicates that the problem with the alternator.
