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
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.
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.
check your alternator or make sure the starter is on correctly
Alternator
did you check the alternator??
Inside the alternator
You have a bad alternator.
Voltage regulator or loose wire.
Check the battery cables or starter.
If the car has a bad battery the battery will not charge just becaus you put a new alternator in try raplacing the old battery.
