This is what I would do in this situation:
-Check battery posts for clean and tight contacts. Check your main ground connections. That is: the two blue cables going from the negative battery post to the engine compartment and engine block.
-Also,make sure the battery is charged: 12 to 13 Volts between posts. If not, you may have a problem with the charging circuit: Recharge the battery, start the car if possible. Check the voltage again while the engine is running. You should read 14+ Volts between battery posts. If not, the voltage regulator may be bad. It is fastened to the alternator. You need to remove the alternator for easy access to the regulator. It has two carbon brushes. Those brushes wear out. If they are about 1/4 inch or less in heigth, you need to replace. An aftermarket regulator is about $20.00 . AT the same time, check the condition of the slip rings that make contact with the brushes, inside the alternator. Those surfaces must not be grooved by wear due to the friction with the brushes.

Let me know what you found out.
