Narrative:

I notified ZMP of the generator failure and requested vectors to the nearest VFR airport. ZMP asked if I wished to declare an emergency and I did declare emergency. I shut down all electrical system except the KX155 communications radio. After receiving vectors, I naved to the O'neill VOR by hand- held radio. I became established on the outbound VOR heading. The cloud deck was approximately 400 ft thick. Upon reaching the initial approach altitude, I was in VFR conditions. The descent and landing were uneventful. I remained in contact with center until landing. Upon landing, I immediately contacted columbus AFSS and canceled my IFR flight plan. The key to the safe resolution was a thorough WX briefing, including the knowledge of the location of VFR conditions, cooperation of ZMP, use of a hand-held VOR receiver, immediate recognition of the problem, and good fortune. The aircraft was checked at O'neill by an a&P mechanic. VFR conditions existed to the east. The battery was recharged. The problem resolved itself partially on the way back. When the generator was charging, I filed an airborne IFR flight plan, but was at all times in VFR conditions. I landed at ames, ia, short of my destination due to thunderstorms over southeast ia.

Title: AN ACFT, PROBABLY A SINGLE ENG, HAS GENERATOR FAILURE AND GETS HELP FROM ARTCC.

Narrative: I NOTIFIED ZMP OF THE GENERATOR FAILURE AND REQUESTED VECTORS TO THE NEAREST VFR ARPT. ZMP ASKED IF I WISHED TO DECLARE AN EMER AND I DID DECLARE EMER. I SHUT DOWN ALL ELECTRICAL SYS EXCEPT THE KX155 COMS RADIO. AFTER RECEIVING VECTORS, I NAVED TO THE O'NEILL VOR BY HAND- HELD RADIO. I BECAME ESTABLISHED ON THE OUTBOUND VOR HDG. THE CLOUD DECK WAS APPROX 400 FT THICK. UPON REACHING THE INITIAL APCH ALT, I WAS IN VFR CONDITIONS. THE DSCNT AND LNDG WERE UNEVENTFUL. I REMAINED IN CONTACT WITH CTR UNTIL LNDG. UPON LNDG, I IMMEDIATELY CONTACTED COLUMBUS AFSS AND CANCELED MY IFR FLT PLAN. THE KEY TO THE SAFE RESOLUTION WAS A THOROUGH WX BRIEFING, INCLUDING THE KNOWLEDGE OF THE LOCATION OF VFR CONDITIONS, COOPERATION OF ZMP, USE OF A HAND-HELD VOR RECEIVER, IMMEDIATE RECOGNITION OF THE PROB, AND GOOD FORTUNE. THE ACFT WAS CHKED AT O'NEILL BY AN A&P MECH. VFR CONDITIONS EXISTED TO THE E. THE BATTERY WAS RECHARGED. THE PROB RESOLVED ITSELF PARTIALLY ON THE WAY BACK. WHEN THE GENERATOR WAS CHARGING, I FILED AN AIRBORNE IFR FLT PLAN, BUT WAS AT ALL TIMES IN VFR CONDITIONS. I LANDED AT AMES, IA, SHORT OF MY DEST DUE TO TSTMS OVER SE IA.
