Take the car or even just the battery to your local auto parts store. They can test it and tell you what you need for zip as long as you purchase the parts to repair it from them.

The most common cause for your 1997 Honda Civic lights to dim is a bad alternator. The alternator is not charging the battery. The battery retains a small charge, but not enough charge to run the engine.

My head lights get brighter during acceleration. I have replaced the alternator. What causes the battery light and the air bag light to flash on and off when driving a 1994 Ford Taurus Wagon 3.8L?
your alternator was never the problem. Its your battery and/or charging system. the reason the lights get brighter is because the car isn't getting the propper amount of energy from the battery and is having to directly draw off of the alternator. when the engine is rev'ed the alternator spins faster creating more current to charge the battery, witch is why the lights brighten at higher rpms.
On a 1988 Toyota Camry what does it mean when the brake the charge and the tail light warning lights come on and all your lights dim and if they dont turn off your battery dies?
Possibly a bad alternator (the system is not charging the battery).
What would cause your 98 Honda civic dx to not hold a charge on battery-you changed alternator and battery is not holding charge-electrical system is going up and down-in other words when lights are o?
Have you verified that the replacment alternator is working? Test both the alternator and the battery. If a battery is allowed to go completely dead and then it sits for a few days it will "sulphate", meaning that the lead plates turn to lead sulphate, making them unable to hold a charge.
Can my car start with a recharged battery if my alternator is bad?
Yes, the battery starts the engine, and as long as the battery is fully charged the engine will start. The battery will loose it's charge if the alternator is defective and not replenishing the charge of the battery but the alternator has nothing to do with starting the engine.
How do you tell if the battery is dead in the Chrysler sebring jxi or if it's the alternator?
if the battery is dead, there will be no ignition lights etc when u turn the key your headlights would be very dim if on at all. the alternator only works when engine is running, so if alternator is dead it will not charge the battery most auto stores will check both battery and alternator for free if you remove from car and take them to the store
Can a loose positive battery cable prevent the alternator from charging the batter and can it cause a battery drain while the engine is not running?
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
Why are vehicles designed to allow their batteries to flatten when their lights are left on?
That's not a design feature, that's a flaw! When the lights are turned on, they draw power from the battery. If your engine isn't running to allow the alternator to charge the battery, then sooner or later the lights will use up all the stored power in your battery. simples.
