My voltage drops for a number of reasons. I have heard that GM cheaped out on the wiring and used wiring that'* much too small. I will be running some extra wiring inside my car to see if that helps alleviate the problem with the voltage dropping so often.
However, I am able to start my car without any problems. I have an optima battery, but I doubt that makes a difference in this case.
I'm going to say its your battery. Even if you had it tested, it won't come back as completely failed if it holds any measure of a charge.
