Inspect your battery negative (ground wire) at the engine block. After 10 years, the OEM Negative cable becomes brittle and creates a high resistance (hot spot) at the cable connection to the engine block. It is often the most overlooked item when troubleshooting the charging system.
You can have a custom Negative side post terminal fabricated using 2 ga. battery cable, and you can save money if you remove your old cable and take to a shop equipped to make them. A welding supply shop is an possible option. Be sure to order extra grounding connects [at the battery terminal], too. You should have at least 2 if you want to upgrade the sound system in your Sunbird.
Your other option is to purchase a service replacement, which you can order from most auto parts sources.
Unless there are visible signs of damage or any evidence of a white powdery residue near the ends of the positive cable, the cable usually doesn't need replacement.
Just install a new battery stud in the terminal, if yours is worn.
No way, only if the battery fails under a load test
The computer only resets when the battery is removed. The alternator just charges the battery, so if the battery is left connected when the alternator is replaced, the computer should not reset.
Repair the alternator to battery connections or replace the battery.
2002 Mazda tribute, what is cylinder misfire My #5 cylinder has a misfire. Battery light also flickers according to idle. So far not alternator. Alternator and battery was replaced maybe 2 years ago.

You have a bad alternator.
Check the battery cables or starter.

Alternator is not charging. Have it tested and/or replaced.
Voltage regulator or loose wire.
The battery light coming on in your Town and Country minivan means that the alternator needs to be replaced. The alternator charges the battery and if it goes bad it will not charge the battery.
It could be an alternator. Check with a mechanic if that is the issue.
Normally it means the alternator is defective.

94 Buick Lesabre replaced battery and alternator and the alternator is not charging the battery. Battery light is on and off. Is this fusable link. If so where is it located
You can have the alternator tested free of charge at just about any major auto parts store. By the way, a bad alternator will not "discharge" a battery - the alternator's function is to provide the charge to the battery. If the alternator is faulty, then it is not providing the charge necessary to keep other components from discharging the battery. I had the alternator tested and it was charging. If the alternator has a bad diode, it will discharge the battery. I replaced the alternator and everything is fine.
Your belt is correctly tensioned?
check the alternator. Use a digital multimeter and with engine running you should have 13-14 volts at the battery. If less than 12.5 Alternator is not charging Also check the amperage the alternator is putting out.
