I would bet that your serpentine belt is loose which is causing the belt to slip on the pulley of the alternator. If this is the case it will happen more when it is raining and when you accelerate. This would probably be the result of a failed belt tensioner. To test this theory you can just push on the serpentine belt. It should be quite tight. If it isn't this, then I would say that it is your alternator on its last leg. Good Luck.

Battery being drained over night

Check to be sure that your hood light is turning off when you close the hood. Seriously. (Common problem.)
Remove the bulb from the hood light to see if the problem persists. If the battery no longer drains, replace the hood light assembly.
Also, run the car for a short while, then turn the car off. Leave the car off for an hour, then feel the back of the alternator. If it is hot, the diodes are bad in the alternator.

Why is my volt light flashing off and on?

Your alternator is bad. When the car drove home fine it was running off the battery and not the alternator. Replace the alternator, and the belt too while you're at it.

My daughter is driving our old 1999 Saturn hatchback. She just called and told me the batter light came on when she started the car, then it starts to flash....The faster she drives, the more the light...

the battery light is for the altenator. It is possible that it is going out. The light comes on when the altenator is not putting out enough voltage to power the you need 12volts and it's only putting out 11 volts. the car will eventually quit running, as soon as the battery is drained to about 5 or 6 volts. the altenator can be checked. she should get back home as soon as possible.

Battery light flashes. Ran a battery test and it came up with No Charging Voltage. Diode Ripple Load on 12.07 Load off 0.0

I would say check altenator for proper voltage and pigtail on altenator for loose bad connection

Blinking battery indicator

the altenator will test fine although if they did not test with a voltmeter on the car reversing the voltmeters probes on the battery I would say the diode is at fault. when a diode goes bad and the battery is fully charged or new the voltage will look fine but the altenator will not charge as it should, a diode keeps the current from reversing which would be called a direct current as all cars have. if the diode is faulty the current will reverse becoming an altenating current a will not produce a charge to the battery

Blue High beam indicator flashing and high beam lights and daytime running lights no longer working

Check your altenator. Mine had the same problem blew all the front headlights, running lights. My altenator was over charging the system. Sounds like you need a new altenator. Pull the bulbs to see if they are blown..if your lucky the fuse just went. Fuses #15,16,17,18 located beside the battery may just be blown also.

After change the new battery, while driving the battery light flash every 3 to 5 mins, please help?

A battery light flashing indicates a problem with your charging system I would have altenater checked, also make sure there is no corrosion in battery cables and insure terminals are tight. Most of the time though it is the altenator.

chances are the regulator inside the altenator is starting to fail which explains the intermittant blicking of battery light. i would imagine that you should have your altenator checked. Oreilly's will check your battery and altenator for free
