No not nessisarily. Some vehicles will run without the battery hooked up some don't. Is your vehicle not charging? If that's what u are trying to test get a volt meter or multimeter you are looking for 14+ volts running at idle. If less then 13 it needs replaced 13 to 13.5 very weak 14 to 14.5 alternator is fine
