Narrative:

VFR flight from O22 to mod in an small aircraft. Uneventful departure from O22 in VFR conditions. Contacted stockton approach (125.1) for advisories. Handed off to mod tower. Mod was calling sky obscured visibility 3/4 fog and haze. Called castle approach for vectors to ILS 28R (radio ok). After clearance for approach was received, intercepted localizer. Handed off to tower (radio still ok). Reported OM. Cleared to land by mod tower. Noticed GS was out and continued on localizer approach. Did not see runway at MDA and proceeded with the missed approach. At the report of the missed, no response from tower. Tried to reach castle approach. No response. Held as published. On the first inbound turn lost all navigation equipment (I was VFR). On the inbound leg airport was spotted and uneventful landing was made. In-flight visibility to the west (at my altitude) estimated 3 mi. Taxied off runway. Was able to reach ground control and taxi to destination. Alternator was found to be inoperative and battery low. Requested to call with details. Alternator replaced and aircraft returned to service.

Title: SMA MAKING ILS APCH DOES A MISSED THEN HAS RADIO FAILURE. FOLLOWS PROC, LANDS.

Narrative: VFR FLT FROM O22 TO MOD IN AN SMA. UNEVENTFUL DEP FROM O22 IN VFR CONDITIONS. CONTACTED STOCKTON APCH (125.1) FOR ADVISORIES. HANDED OFF TO MOD TWR. MOD WAS CALLING SKY OBSCURED VISIBILITY 3/4 FOG AND HAZE. CALLED CASTLE APCH FOR VECTORS TO ILS 28R (RADIO OK). AFTER CLRNC FOR APCH WAS RECEIVED, INTERCEPTED LOC. HANDED OFF TO TWR (RADIO STILL OK). RPTED OM. CLRED TO LAND BY MOD TWR. NOTICED GS WAS OUT AND CONTINUED ON LOC APCH. DID NOT SEE RWY AT MDA AND PROCEEDED WITH THE MISSED APCH. AT THE RPT OF THE MISSED, NO RESPONSE FROM TWR. TRIED TO REACH CASTLE APCH. NO RESPONSE. HELD AS PUBLISHED. ON THE FIRST INBOUND TURN LOST ALL NAV EQUIP (I WAS VFR). ON THE INBOUND LEG ARPT WAS SPOTTED AND UNEVENTFUL LNDG WAS MADE. INFLT VISIBILITY TO THE W (AT MY ALT) ESTIMATED 3 MI. TAXIED OFF RWY. WAS ABLE TO REACH GND CTL AND TAXI TO DEST. ALTERNATOR WAS FOUND TO BE INOP AND BATTERY LOW. REQUESTED TO CALL WITH DETAILS. ALTERNATOR REPLACED AND ACFT RETURNED TO SVC.
