Car will not turn over

So, you've had a professional test your battery to ensure it is fully charged and also capable of handling the voltage drop and surge of a starter motor load? Most folks don't have this test equipment, and if they've had it tested at a repair shop that does have the equipment, you'd probably have resolved this concern by now. How do you know your battery is good? It's the first thing to think of in an occasion like this. Take the time to have the battery properly tested for state of charge and the ability to sustain a load.
