Narrative:

Approximately 10 mins after departing srq on instrument flight to gpt, high voltage light came on in my cessna P-210. I requested radar vectors back to srq from tampa approach. My request was granted. After descending through cloud deck, I lost all electrical power. I switched to my hand-held transceiver to contact srq tower and was given radar vectors to airport and cleared to land. I landed without incident and my flight plan was closed. Probable cause: defective voltage regulator.
