Narrative:

I was flying (by myself) my beech musketeer super III. The sky was clear; but a tad hazy and somewhat turbulent. After flying for about an hour my radios started to make a cracking sound. At approximately fifteen miles from [my destination]; I keyed for the tower. At this time there was a crack sound and all electric; radio and GPS went out. I checked all other instruments and only the electric was gone.I circled away from the airport pattern to consider my options; always surveying for traffic. The thought of looking for a non-towered airport close by was hindered by my GPS flashing on and off. I also was aware that the electric may not be my only problem; and I did not want to become a glider for an off field landing if I could prevent it.having knowledge of the wind direction for the landing pattern; I made a decision to survey the total area several times and go for a short field landing and quick departure from the active runway. I had no way to contact the tower; but surveyed the area several times before taxiing down the tarmac.at this point I stopped in the tie down area and a young woman in a golf cart came to me with a note to call the tower; which I did. The repair was to fix two wires that had parted from the alternator during flight.
