First, check the battery terminal connections, they should be clean and tight, next check the battery surface voltage, if below 12.4 volts the battery needs to be charged before you can go further. If the battery does not accept a full charge replace it with a new unit. After installing the battery start the car and test the alternator output, it should be between 13.6 volts and 14.2 volts at idle. If the voltage is lower replace the alternator with new and retest system. Please let us know how it goes, Thanks for visiting 2CarPros. Com :D
