A C172 IN CRUISE DIVERTED DUE TO COMPLETE LOSS OF ELECTRICAL PWR.

Narrative

I LEFT CALDWELL AT ABOUT XA30 LCL FLYING 090 DEGS; THEN SBOUND HUDSON RIVER UP TO VERRAZANO BRIDGE. OVER THE BRIDGE AT ABOUT XB00 LCL; I DECIDED TO CHANGE THE FREQ TO NEWARK TWR REQUESTING TRANSITION BACK TO CALDWELL WHEN I EXPERIENCED LOSS OF ELECTRICAL PWR. ALL RADIOS; LIGHTS; AND ALL OTHER EQUIP THAT REQUIRES ELECTRICAL PWR SHUT OFF. I WAS NEAR NEWARK ARPT; AS A CLASS B; I WOULD NEVER GO THERE; AND SO I DECIDED TO GO NBOUND ON THE RIVER IN ORDER TO GO BACK TO CDW. WITH ALL THE NECESSARY PRECAUTIONS I GOT THE GOLF COURSE RIGHT NEXT TO THE ALPINE TWR CHK POINT. AS I TURNED L; I TURNED TO GET ON TETERBORO; I SCANNED FOR TFC; AND I HAD MY XPONDER ON 7600; I WAS NOT SURE IF THEY HAD GOTTEN MY SIGNAL; BUT SINCE THE AREA WAS SO CLR; AND AFTER SEEING THAT WAS SAFE FOR LNDG; I DECIDED TO DO SO. I COULD NOT FLY BY THE TWR IN ORDER FOR THEM TO SEE ME BECAUSE THIS INCIDENT OCCURRED AT NIGHT. THEY WOULD NOT BE ABLE TO SPOT ME; SINCE ALL OF MY LIGHTS WERE OFF. I LANDED SAFELY ON RWY 24; AND AS TETERBORO'S SECURITY APCHS ME I RPTED TO THEM OF WHAT HAS HAPPENED. AND THEN I CALLED THE TWR IN ORDER TO RPT THE REASONS FOR MY LNDG.
