Narrative:

I had a total electric failure just after I was cleared for the ILS approach for runway 5 in macon regional airport. I still tried to squawk 7700/7600 and hoped they would notice my problem. I waited for a cleared to land signal but I did not get any light signal. Anticipating that they did not know I had an emergency, I decided to land rather than going missed approach. After I landed and got clear of the runway, they gave a light signal to taxi to the ramp, which I also did. Afterwards we found out that we had an alternator failure. Before we started flying and during the flight I also checked my amps indicator, but we also found out afterwards that one was inoperative.
