My ST alternator took some time to completely fail. During the decline, I saw all kinds of random electrical issues. My advice-go ahead and replace the alternator unless you don't mind needing to tow the car (or you travel really short distances). At some point, you'll find every electrical system completely shut down (one of your computers will funnel all available battery energy to the engine and fuel pump). From that point you've got a very short distance till the battery is exhausted. This doesn't mean the battery is toast!

Having the system tested is of little value. My car-the "BATT" light was ON when it was tested, and I was told it needed a new battery. Indeed, until the very end, the voltage provided by my alt was about 14.4VDC-even with the light on.

Replace the alternator now or do it later after a tow.

Most auto parts stores will test an alternator for free, or use a good garage or mechanic. Sounds like it's going bad.

Sudden loss of power

Are you sure the battery is being drained during this process? That would be a major draw from something, but then you said "...suddenly full power again,". It sounds more like a connection or a terminal working loose at times, not able to pass normal voltage. You sure need a voltmeter, my friend.

I think I would want to have that new alternator tested again, just to make sure it is not defective. A lot of aftermarket parts are turning up like that. Did you replace the alternator and battery because this condition was present? Do you know your battery cables and ground points are all good and secure, and corrosion free? You might want to double check all the grounds you can find- the battery negative cable, the engine to body strap, or cable, maybe an engine and computer harness ground point-look around the top of the engine for a ground wire coming out of the engine wire harness and going to ground at a nearby bolt. Also check all alternator connections.

If you have to keep looking, look at the power side of the power distribution scheme. From the battery, power goes to the Power Distribution Center, maybe called a junction box or junction is where the fuse and relay block under the hood receives power, both from the battery and the tie-in from the alternator, and then distributes it to the major circuits for the car. With all your symptoms, it sounds like the problem is not far from the battery in the power distribution. Sayeth Dr. monte. Good luck.

New battery drains.

I can't imagine how changing the belt would have any effect on the electrical system if the alternator is working.
The way you check for a drain is to disconnect the battery ground cable and use a test light to make the connection between the battery and ground. If there is something drawing power from the battery the light will glow.
Then you pull each fuse from the fuse boxes until the light goes out. You also disconnect the starter and alternator if necessary.

Battery and brake light on

When the brake light and battery light come on at the same time on a Nissan, it is most likely the alternator. Perhaps you got a faulty alternator or it has failed already. Another possibility is a bad connection from alt. to batt.

6 weeks ago, my car 2002 civic would not start. It made this really weird clicking noise..A guy jumped me and then all of a sudden it worked fine. He said the posts needed to be cleaned though, so I had...

the clicking noise was due to the bad battery. the starter solinoid was not getting enough power to turn it over. try this if possible, engine off at battery should be at least 12.6 volts. start the car and if alternator is ok, it should read 14.2 to 14.7. if not repair alternator. what happens, is the voltage regulator in alt. goes bad and will not supply enough current to battery. good-day !

My car suddenly won't start. There is a constant clicking noise and the dash lights are going on and off in synch with the clicking noise. It doesn't appear to be the battery. Any idea what the problem...

Sound like a low battery, lights left on or not charging. Try boosting it. If starts and then stalls the alternator not charging. If it starts and keeps running its probably a low battery or a drain.

Is my alternator bad??

You are definately not charging. Have you lost your alternator belt? If not, then yes, your alternator is probably bad. After you connected the new battery, did the problem stop? The reason I ask, is if you have a bad connection the battery can't charge properly. You can have your alternator tested for free at Advance or Auto Zone. Good Luck. Hope this helps!
