Put a voltage meter on the battery, Note the reading, and start the engine, the reading now with it running should be higher. I would be happy seeing 13 to 14.5 volts on the meter with it running.
Have you checked for a voltage draw on the battery when the key is in the off position. Also make sure the Alternator is charging.
What kind alternator is? Is Bosh or different kind?
Your 12 volt battery should be about 12.5 volts without the engine running. Test and verify it is. Now with the engine running test again, Voltage should now be around 13 to 14 volts. If not, then your battery or alternator are bad. To check a battery try charging it with a battery charger.
A loose connection in the wiring
Check to see if the engine charging system is producing at least 12dc volts
To change the alternator on a John Deere 316, first disconnect the battery to ensure safety. Remove the drive belt by loosening the tensioner, then unbolt the alternator from its mounting bracket. Disconnect the electrical connections and remove the alternator. Install the new alternator by reversing these steps, ensuring all connections are secure and the belt is properly tensioned before reconnecting the battery.
Check with your John Deere dealer. No, not Home Depot or Lowe's but an actual business that works on and sells John Deere mowers.
Check your stator or your charging system.

On the John Deere STX 38 riding mower, the alternator is typically located near the engine, often mounted on the side of the engine block or near the flywheel. To access it, you may need to remove the engine shroud or cover. Always refer to the owner's manual for specific details and guidance on accessing and servicing the alternator.
