Normally when the alternator is downpowered for any reason(fails) and all thats left is battery voltage /power, you get the light..take the car to a local autozone or advance store and they will test the system for free..or you can start the car and put a voltmeter on it and see what it reads..should show at least 14.5 volts, if not then its replacement time..good luck

New alternator new battery 2 new sensors on a 2002 Cadillac and battery is draining over night

Check for lights that are on like sun visor lights in the vanity mirrors and other lights like console and glove box, it is always one of them that is the cause. You can also hook up a meter and watch the draw as you pull fuses to id the circuit that is the cause of the parasitic battery drain.

Batterie and brake light stays on changed new batterie new alternator car ran fine the next day the car would not crank

There is obviously have a drain on the battery. You have a faulty break light pedal switch causing the lights to stay on, or your turn signal switch is bad. your brake lights run through, the turn signal switch too. That could also cause the problem.

1999 Sentra Battery Drain

The most common cause of battery drains is that one of the interior lights is on, check the visors if they are lights and the glove box light under hood and trunk lights, check the interior at night to see if any lights are on, the next step is that the Alternator has a failed diode and is causing a draw. Also have the battery tested for a bad cell, that to will draw the battery low.

Which one is the fuse for the inside lights? the inside lights stay on the whole time and i need to change it! plus is causing my battery to die

Your inside lights are staying on
If the fuse was blown they would be off
So forget the fuse.
Why would you replace a good fuse with
another good fuse?

It is not causing your battery to die
The problem that causes your light to
stay on is the cause of the battery drain

We can't diagnose or guess over the
internet,you need help from a friend or
repair shop

My brake light and battery light stays on when driving. Also emergency brake does not work.

OK, the brake light is caused most likely by the emergency brake cable being broken, and the pedal or brake lever is not in position.

Also, the brake light could be caused by low brake fluid level. Check that, too.

Battery light, is caused by the charging system not working, like a bad alternator or shorted out battery, or both.

I would have these issues repaired before driving any distance.

Red battery warning light

Have the alternator and battery checked.
If the alternator isn't charging, that would cause the light to come on.
If the battery is bad and not holding a charge, do to a weak or dead cell, that would also cause the light to come on.

Battery goes dead overnight

This could indicate a weak battery or a drain caused by some electrical circuit turned on. Some parts stores will run a free battery check for you. You don't mention your location or the age of the battery, (Cold weather may cause problem to be more obvious.) Make sure all your lights are off - a trunk light or glove box light could stay on because of a stuck switch. Make sure nothing is plugged into the lighter that would cause a drain.

Something killing the battery

check for any lights staying at night, dome lights, sun visor lights for vanity mirror, glove box lights and so on, also have the battery tested, a bad cell can cause the battetry to run itself low, any Autozone or Kragen will test the battery for free.
