Battery dead jump start runs but when i turn on light or put in gear it dies

It sounds like that not only is the battery totally dead ,due to a high very internal resistance, but that the alternator has very low output. While car is idling in neutral, the alternator has just enough output to supply the ignition circuits but once in gear and the idle speed drops there is insufficient voltage to run engine so it stalls, It is the same when the lights are turned on as the alternator cannot supply enough to run lights so engine dies without enough drive for the ignition circuits. Try another battery or install a new one. Also have the alternator output checked as it could be the cause of the battery dying in the first place because it has not been maintaining charge as you drive. The alternator problem would be caused by either worn brushes and / or a faulty electonic voltage regulator which is mounted inside the alternator with the brushes.
