Small Engines (Lawn Mowers, etc.): blowing fuse, headlight assemblies, proper voltage

Question
I own a Craftsman 42 in riding mower that keeps blowing the only fuse it has.My question to you is what would cause this and how can I fix the problem?  

Answer
 Hello Anthony:

 For this Type of Problem you will need to Inspect the Harness for Bare Wires. Check the Headlight Assemblies. Check the Charging System for Proper Voltage (13 to 13.5VDC). Over Charging will Blow the Fuse Too. If you send me the Model Number of the Mower(not the Engine) I might have a Schematic of the Harrness to Assist us Further. Hope this Helps. Let me know what Happens, Please.

 Good Luck

 Respectfully

 John
