Re: replace battery warning light
If it is in the instrument cluster U will have to pull the cluster to get at the bulb, make sure the problem is the bulb, I have never seen one burn out, most times it is either a loose connection at the bulb or the indicator signal wire at the alternator.

There should be a fuse or fuseable link between the battery and the alternator. Check the voltage at the battery wire on the back of the alt - should be 12 volts or more. The alternator is turned on by the ASD relay and the computer. If the engine is running I will assume the relay is working. If you have battery voltage on the big wire and the alternator is not charging, you could have a problem with the computer.
the alternator is a doodle to change ,when you know how ?? was it a new recon unit or a secondhand scrapyard job---- check for power to teh large terminal the start engine and disconnect neg battery terminal if engine stops alternator fault ,if engine keep running but red light still on then its warning light control fault which is built into alternator so change alternator .
mcdevito75 here, The replaced alternator should have a warrantee, bring it back to the shop that replaced it. If you did the work yourself and even if it's a rebuilt, you should still be able to exchange it. Some manufactureres recommend a new alternator and not rebuilt, plus if you"ve added any moe electrical items you"ll need a stromger alternator (higher amp).
Check for bad connection to the battery. Use a volt meter to check voltage from alternator to the battery, should be 14.5 volts to 15 volts. If you have anything less than that then look for a bad alternator wire from alternator to battery. Also check for a good ground connection to the battery. Do all the testing with everything off inside the car so you will not have a power drain from the system. hope this will help you.
I am 99% sure it is the alternator. They are called throw away alternators because dealers are not supposed to rebuild them however I worked at a dealership for over 20 years and rebuilt 100's or more. If you know where an alternator/starter shop is, that would probably be the cheapest way to go instead of buying one.
You need a new alternator. Also check to be sure that your serpentine belt didnt break. The car was not charging the battery (either the belt broke or the alternator is bad) and running entirely off the battery causing the lights to dim and the voltage light and check charging system lights to come on. Good luck to you. Thanks for using fixya!
