Narrative:

Jun/xe/95, en route to redding airport from sun river, oregon, I experienced an electrical failure to the system of my grumman tiger. I landed at redding and the alternator was repaired, the battery charged and a maintenance release was issued by maintenance. The following morning I proceeded on course to reedley airport. However, I again experienced an electrical failure, and I landed at visalia municipal airport for repairs. The battery was checked, an attempt to charge it was made, and the battery was then replaced with a new one. The system was checked, the aircraft electrical system was run, and I proceeded on course to my final dst of torrance airport. En route, not knowing if the system had been repaired completely, I used the radio and transponder only when necessary. Prior to entering the los angeles area, I monitored the ATIS at van nuys for an altimeter setting and descended down to 4900 ft from 7500 ft to be under the los angeles class B airspace of 5000 ft and over the class C airspace of burbank of 4800 ft. I turned my transponder to standby to warm up and then switched it to the altitude setting. As I was leaving the burbank class C airspace, and prior to descending to 3500 ft for the la special flight rules area, I observed a large commercial aircraft in front of me, climbing nwbound. I believe it was approximately 500 ft above me. I glanced at my altimeter setting, which was 4900 ft, and continued on course, descending to 3500 ft. I changed my transponder to VFR and transmitted my position through the la special flight rules area. While transiting the area, someone kept asking me what my north number was by referring to the make of my aircraft. Upon responding, I received no reply. Perhaps it was lax, I don't know. I know I was at the correct altitude and locations at all times. Upon exiting the area, I descended to torrance VFR, cautioning them that I had experienced intermittent electrical problems en route. I squawked identify at their request and turned off everything else, except 1 radio. I was cleared to land without additional problems. A prior report was made on jun/xa/95 relating to an electrical problem upon leaving the torrance area nwbound. The aircraft was repaired prior to continuing to sun river, oregon. A complete check of my aircraft prior to leaving torrance on jun/xa/95 was made, and the entire system was rechked after returning.

Title: PLT EXPERIENCES REPEATED ELECTRICAL PROBS DURING FLT.

Narrative: JUN/XE/95, ENRTE TO REDDING ARPT FROM SUN RIVER, OREGON, I EXPERIENCED AN ELECTRICAL FAILURE TO THE SYS OF MY GRUMMAN TIGER. I LANDED AT REDDING AND THE ALTERNATOR WAS REPAIRED, THE BATTERY CHARGED AND A MAINT RELEASE WAS ISSUED BY MAINT. THE FOLLOWING MORNING I PROCEEDED ON COURSE TO REEDLEY ARPT. HOWEVER, I AGAIN EXPERIENCED AN ELECTRICAL FAILURE, AND I LANDED AT VISALIA MUNICIPAL ARPT FOR REPAIRS. THE BATTERY WAS CHKED, AN ATTEMPT TO CHARGE IT WAS MADE, AND THE BATTERY WAS THEN REPLACED WITH A NEW ONE. THE SYS WAS CHKED, THE ACFT ELECTRICAL SYS WAS RUN, AND I PROCEEDED ON COURSE TO MY FINAL DST OF TORRANCE ARPT. ENRTE, NOT KNOWING IF THE SYS HAD BEEN REPAIRED COMPLETELY, I USED THE RADIO AND XPONDER ONLY WHEN NECESSARY. PRIOR TO ENTERING THE LOS ANGELES AREA, I MONITORED THE ATIS AT VAN NUYS FOR AN ALTIMETER SETTING AND DSNDED DOWN TO 4900 FT FROM 7500 FT TO BE UNDER THE LOS ANGELES CLASS B AIRSPACE OF 5000 FT AND OVER THE CLASS C AIRSPACE OF BURBANK OF 4800 FT. I TURNED MY XPONDER TO STANDBY TO WARM UP AND THEN SWITCHED IT TO THE ALT SETTING. AS I WAS LEAVING THE BURBANK CLASS C AIRSPACE, AND PRIOR TO DSNDING TO 3500 FT FOR THE LA SPECIAL FLT RULES AREA, I OBSERVED A LARGE COMMERCIAL ACFT IN FRONT OF ME, CLBING NWBOUND. I BELIEVE IT WAS APPROX 500 FT ABOVE ME. I GLANCED AT MY ALTIMETER SETTING, WHICH WAS 4900 FT, AND CONTINUED ON COURSE, DSNDING TO 3500 FT. I CHANGED MY XPONDER TO VFR AND XMITTED MY POS THROUGH THE LA SPECIAL FLT RULES AREA. WHILE TRANSITING THE AREA, SOMEONE KEPT ASKING ME WHAT MY N NUMBER WAS BY REFERRING TO THE MAKE OF MY ACFT. UPON RESPONDING, I RECEIVED NO REPLY. PERHAPS IT WAS LAX, I DON'T KNOW. I KNOW I WAS AT THE CORRECT ALT AND LOCATIONS AT ALL TIMES. UPON EXITING THE AREA, I DSNDED TO TORRANCE VFR, CAUTIONING THEM THAT I HAD EXPERIENCED INTERMITTENT ELECTRICAL PROBS ENRTE. I SQUAWKED IDENT AT THEIR REQUEST AND TURNED OFF EVERYTHING ELSE, EXCEPT 1 RADIO. I WAS CLRED TO LAND WITHOUT ADDITIONAL PROBS. A PRIOR RPT WAS MADE ON JUN/XA/95 RELATING TO AN ELECTRICAL PROB UPON LEAVING THE TORRANCE AREA NWBOUND. THE ACFT WAS REPAIRED PRIOR TO CONTINUING TO SUN RIVER, OREGON. A COMPLETE CHK OF MY ACFT PRIOR TO LEAVING TORRANCE ON JUN/XA/95 WAS MADE, AND THE ENTIRE SYS WAS RECHKED AFTER RETURNING.
