Hello and thank you for your question,

The check charging system light comes on when the alternator stops charging and when the alternator stops charging the battery will slowly loose its charge even if its new. Because you lost charging system power and the voltage dropped that would cause the other warnings to come on. In most cases this type of problem is going to be a failing alternator. The place to start would be to charge the dead battery up and start the engine and check the alternator output voltage. If the alternator is charging you should see right at 14 volts with the engine running. Any thing less would me the alternator has failed.
