Narrative:

Oct/thu/91 filed IFR out of nashville, tn, (bna) to charleston, wv, (crw) on the first leg of a flight back to penn yan, ny, (N22). Takeoff time was PM45 CST. I was cleared to hazard VOR (azq). Prior to hazard, ZID reported that they were not picking up my transponder and to report hazard. I reported azq and 7000 ft. Center did pick me up for a short time, then reported they lost radar contact again. I checked my ammeter and it indicated charging. I checked the circuit breakers and they were ok. I was having difficulty receiving center and requested a frequency change which I was given. My DME went blank and I was getting a loud hum from the strobe lights which I then shut down. I reported to ZID that I was experiencing an electrical failure and request to land at the nearest airport. Center had me check a number of things which confirmed failure. Center cleared me to crw and gave me vectors. Told me to expect visual to runway 23. I was losing reception and they turned me over to crw approach. I shut down all electrical which was not needed. I was clearing to right base runway 23. I reported the airport in sight and turned over to tower. Crw tower asked if I wanted runway 15 which I was already on a right base for. I accepted and landed on runway 15.
