Narrative:

I departed red bluff municipal airport on an IFR flight plan to medford jackson county airport. After departure experienced low voltage causing transponder to become inoperative. Everything else seemed to be operational. Cycled master, didn't help. ATC advised to turn off transponder to conserve electricity. I complied. At approximately 20-30 NM south of fort jones loss of 2-WAY radios and navigation sides. Loss of fuel gauges. At this point decided to proceed to nearest VFR airport where repairs could be made which was medford. Landed in VFR conditions at medford with appropriate ATC light signals. I made this report upon request of the medford control tower. I also received a phone call from inspector of hillsboro FSDO. He also required this report, told me that it was mandatory and that I had nothing to worry about. I never declared an emergency.
