Narrative:

On aug/xa/06 I was en route to corona (ajo) from parker (P20). I was on VFR flight following and had just been handed off to palm springs approach; I called up and let them know I was with them at 8500 ft. I was at approximately 329 degree radial of palm springs VOR; 12 NM out when they gave me a TA. When I went to respond my headset gave a loud static and then I lost all electrical power to my plane -- my GPS; vors; transponder -- everything. I went to my flight bag and pulled out my handheld radio; informed palm springs of problem and requested frequency change and squawk 1200. This was approved. I now had my hands full descending down the banning pass skirting the march AFB class C airspace; then over riverside airport class D; then lastly ontario class C. The approximately 1 1/2 NM incursion occurred over pdz VOR in ont class C airspace. I used my handheld radio to land at corona (ajo). The problem was later found to be alternator at voltage regulator failure. Problem resolved.
