After changing The alternator on a 98 ford excort, does the battery need to be charged?

you need to make sure you check the alternator fluid, if thats low watch out.....that could be bad. Also if your battery keeps dying...check the blinker fluid, there might be a leek.|||It depends on if you drained the battery befor changing the altenator, More than likely you probaly will just have to jump start it, and let it run for a while. You also may need to get a new battery if u drained it to much or its old and such|||Not unless the battery is already dead, just ,make sure you follow instructions for reconnecting the battery you could damage the alternator.|||If the battery is dead the alternator will not work.The alternator needs 12VDC for the exciter field.|||The alternators job in a car is to charge the battery after starting, and to run the engine%26#039;s ignition system while it%26#039;s running. It also does all those nifty things like power your radio and lights. If the car will start, you don%26#039;t need to change the battery. Furthermore, current batteries have a typical life of 4.5 to 5 years. It%26#039;s likely that the battery in your Escort was replaced in 2002 or 2003, so unless you completely drained it of energy which can damage your typical lead acid battery, it%26#039;s likely that your current battery will last you a good one or two more years.|||Yes. It is a must that you have a fully charged battery. You need proper voltage on many alternators before it will energize. A low battery can kill an alternator. Also, never run a car with the battery disconnected.|||if it starts don%26#039;t worry about it. just check the alternator is working and it will charge your battery. if you can%26#039;t get it to start charge it at a low setting of like 2 amps.
