ACFT HAS MECHAL PROBS; PLT HAS LOST COMS; DIVERTS TO NEAREST ARPT.

Narrative

I DEPARTED DOYLESTOWN (DYL) IFR FOR BEAVER COUNTY (BVI). CONDITIONS WERE VMC THROUGHOUT THE FLT. AFTER I HAD REACHED MY ASSIGNED ALT OF 6000 FT; PHILADELPHIA APCH ADVISED ME THAT THEY COULD NOT RECEIVE MY XPONDER. I CONTINUED ON MY ASSIGNED RTE AND SHORTLY WAS ABLE TO HEAR BUT NOT TALK TO PHILADELPHIA APCH. NEAR BOYER INTXN I SWITCHED FREQS TO ZNY. THEY RECEIVED MY XMISSION AND I TOLD THEM THAT I HAD COM PROBS WITH PHILADELPHIA APCH. I THEN NOTICED A LOW-VOLTAGE LIGHT AND SHUT DOWN UNNECESSARY COM AND NAV EQUIP. I ATTEMPTED LOST COMS PROCS BY SQUAWKING 7600. I THEN CALLED FLT SVC ON MY CELL PHONE AND TOLD THEM OF MY LOST COM PROBS. WHILE ON V170 A FEW MI FROM RAVINE VOR MY FUEL GAUGES FAILED. I THEN SQUAWKED 1200; UTILIZED THE 'NEAREST ARPT' FUNCTION OF MY GPS WHICH IDENTED BENDIGO (74N) AT 9 MI. I STARTED A DSCNT; TURNED TO A DIRECT HDG FOR BENDIGO AND LANDED. WHILE TAXING I WAS ABLE TO TALK TO A COMMUTER AIRLINER AND TOLD THEM I WAS ON THE GND; WHICH I BELIEVE THEY RELAYED TO ZNY. AFTER PARKING I WAS TOLD BY A PERSON ON THE FIELD THAT BENDIGO ARPT WAS CLOSED BY NOTAM TO TRANSIENT ACFT. I TELEPHONED FLT SVC; TOLD THEM MY LOCATION; THAT I HAD LANDED AT AN ARPT CLOSED BY NOTAM TO TRANSIENT ACFT; ASKED THEM TO ADVISE ZNY AND CLOSE MY IFR FLT PLAN. I ASKED IF THERE WAS ANYTHING ELSE I NEEDED TO DO. THE FLT SVC ATTENDANT SAID NO; AS FAR AS HE WAS CONCERNED I HAD AN EMER.
