    Last mower similar to this that I worked on that had a similar problem was caused by one of a few things.

    Battery was bad - shorted cell or low on water. Check battery.
    Poor battery connections - rust or not tight. Clean and tighten.

    Try unplugging the voltage regulator. If it quits blowing fuses, the chances are the stator may be shorted to ground.

    some thing is grounded, get a schematic from your dealer, and chase it.

    Unpluging the voltage regulator does not tell you all that much about blown fuses. It could be a bad voltage regulator, a bad battery or a short in the wiring. To test for a stator shorted to ground , with the engine off unplug the voltage regulator and take a test meter and set it to OHMS. Test between the stator leads , the two out side wires on the plug and the frame of the engine. You should get OPEN (no reading or a very very high reading, in the Megaohm range) between the startor leads and the frame. Now between the stator leads them self the reading should be low, less than 5 ohms if I remember right. A very weak battery of one with a dead cell will blow fuses because the voltage regulator is overloading trying to charge a bad bad battery. Remove the battery and put it on a battery charger over night and then try it.
