I've seen bad battery clamps cause a similar problem also. My wife's car had good voltage. I could measure 12 Volts, radio and other accessories worked, but cranking would drop the voltage to near 0. Finally I looked under the hood while she cranked it over and I saw a little puff of smoke come out between the wire and clamp. I touched the clamp and it was very hot.
