Narrative:
Lost electrical power and alternator did not seem to be charging the battery. We were over the ocean outside the sna class C airspace. Radio worked enough to contact socal approach. They responded with 'proceed to john wayne, enter,' then radio stopped working. So, I squawked 7600 and proceeded. I circled twice over the 405 freeway, about 3-4 mi west of airport. I crossed over field above tower at 1300 ft. Looked for light gun signals and landing on runway 19L (instead of interfering with landing carrier on runway 19R). On the ground, waited until all traffic was clear of taxiway, then taxied to parking. No problem during taxi. While waiting in midfield runup, I watched for light signals. Called tower to inform what happened.

Title: INSTRUCTOR PLT OF AN SMA SEL SQUAWKED 7600 AND FLEW OVER THE ARPT FOR LIGHT SIGNAL CLRNC AFTER EXPERIENCING A COMPLETE ELECTRICAL FAILURE. RPTR MADE A SUCCESSFUL LNDG.
Narrative: LOST ELECTRICAL PWR AND ALTERNATOR DID NOT SEEM TO BE CHARGING THE BATTERY. WE WERE OVER THE OCEAN OUTSIDE THE SNA CLASS C AIRSPACE. RADIO WORKED ENOUGH TO CONTACT SOCAL APCH. THEY RESPONDED WITH 'PROCEED TO JOHN WAYNE, ENTER,' THEN RADIO STOPPED WORKING. SO, I SQUAWKED 7600 AND PROCEEDED. I CIRCLED TWICE OVER THE 405 FREEWAY, ABOUT 3-4 MI W OF ARPT. I CROSSED OVER FIELD ABOVE TWR AT 1300 FT. LOOKED FOR LIGHT GUN SIGNALS AND LNDG ON RWY 19L (INSTEAD OF INTERFERING WITH LNDG CARRIER ON RWY 19R). ON THE GND, WAITED UNTIL ALL TFC WAS CLR OF TXWY, THEN TAXIED TO PARKING. NO PROB DURING TAXI. WHILE WAITING IN MIDFIELD RUNUP, I WATCHED FOR LIGHT SIGNALS. CALLED TWR TO INFORM WHAT HAPPENED.
