Tried to start my car and it wouldn't start tried it again and the car started with no problem. While driving the radio went out for a second came back on and then the battery light came on for about 2 seconds and disappeared. The lights didn't dim and the battery light never came back on. Any ideas what the problem could be?

    The plunger and contacts in the starter fail and can initially be intermittent they are replaceable at a fraction of the cost of a starter but most people change the starter. First check that your battery connection are clean tight and secure.
    It could be a bad or unsecured battery ground cable between the battery and chassis or chassis and engine. Put a volt meter across the battery terminals with the engine off, at rest the battery voltage should be 12.6 volts if the battery is fully charged. Now get a friend to start the car while you watch the voltmeter, the voltage reading across the battery should read approximately 14.6 volts if the alternator is charging correctly.
