I took my alternator to auto zone and got it tested last year, and it said that it was working fine.

SOURCE: nissan terrano 1996 td27 charging issue.

Did you hear the one about the Terrano with a charging problem?
Just fix it by replacing the thermostat!
Seriously - check your temperature gauge does it take ages for the needle to barely get off cold? (and is the heater useless?)
The needle should get to just below half way in 2 or 3 minutes.
If the thermostat is stuck open, then the engine does not get up to temperature.
The glow plug control senses the engine temperature is cold, so the glow plugs stay on for an extended period of time (sometimes 10 to 15 minutes) - short trips particularly in winter, with more headlight driving - the alternator can't keep up with the current being drawn off and from time to time you will end up with a flat battery!
A thermostat is cheap, and easy to replace (three bolts and about a half litre of coolant - I pumped the coolant from the top of the radiator, and didn't spill a drop when the thermostat housing was removed).
Sure enough, as the engine temperature reached about 50C, the glow plugs turned off.

SOURCE: 02 maxima battery wont stay charged. Took to auto

that seems very, very low. almost what the battery voltage is supposed to be. actually i would say that's not charging and you need to replace the alternator. normal voltage output is 13.5-15 volts

SOURCE: Alternator does not charge battery. Alternator light glows.

check for an inline fuse between the alt and battery,otherwise take a jumper cable from the positive terminal on the battery to the alt. battery terminal output direct and now check for charge

Have new battery, why is battery light still on?


Problem could be the alternator ( battery charger), seems like it doesn't charge battery.
You can test it With a DC meter , with your van Stopped mesure DC voltage (should be around 12 V) , when running should be around 13 V (Depending on the regulator) .
Hope this help you to fix your issue

Car wont start,seems like battery went dead


If the car doesn't start with a jump you might have a bad alternator. The alternator supplies voltage to the car once the engine is running. If the battery is dead, and the alternator isn't putting out sufficient voltage, the engine cannot run. Then again sometimes a car with an extremely dead or internally shorted battery WON'T start with a jump. Replace the battery and try again.

My battey light is on in my 2001 oldsmobile alero


Did you have the charging system and battery checked first before you started throwing parts at the car? Because I'm start to think that its in the wiring from the alternator to the battery (if the alternator was tested good). the symptoms are pointing to a bad alternator with the car not running after a jump. (the car is running off the battery which doesn't have much a charge and then it dies when the battery voltage drops too low). I would bet that your ignition wire to the alternator is bad (or signal wire) which tells the alternator the car is on and to start charging. I had a similar issue with my Honda and only a technician who rebuilt alternators was able to show me how to test it. Seems like you have a similar issue. Have the alternator and battery tested at any local Autozone and if they both test good I would start with the wiring as I suspect this is the issue you have. One of your alternator wires is the ignition wire which puts 12volts to the alternator (turning on the charging) to allows it to put out voltage to your battery.

The car was running fine one day then the next day it would not start. We tried jumping it thinking the battery might be dead and it still would niot start. The car has power until we take the jumper...


Sounds like you have a toasted battery or alternator. Have you performed a load test on the battery? Have you tried to charge the battery? First remove the battery and charge it externally from the vehicle. If the battery won't hold a charge, or won't hold a charge of 12 volts, replace it. Once you have the vehicle started, test the operation of the alternator. It should be putting out at least 13 volts back to the battery to keep it charged - if it is putting less than 13 volts or more than 16 volts, replace the alternator.

I have a few problems. First my van won't keep a charge. Second my van seems to not be able to go beyond second gear. Next when it was running it would die for no reason.


If it's not holding a charge you could have a bad battery or the alternator is not putting out enough voltage to keep it charged. Have your battery tested at auto zone or advanced auto. Once the battery is ruled out the next thing to do is check the alternator, this can be done with the alternator installed on the vehicle, if you have a digital multi-meter or volt meter you can check alternator out put at the battery. If your D.C voltage reading is more than 13 volts than your alternator is working. Your transmission issue is probably linked to the electrical issue since it is an electronic transmission, and requires a certain amount of voltage to operate properly.

you have to have 12.4 volts showing on your battery to even attempt to start your car,, you need to completely charge the battery , ( if you have a walmart near you, they will not only charge it for you, but they run a Load test , which tells how the battery holds up under a Load , such as when trying to start the vehicle,, ) I would venture to say that you have a bad battery ,, it only take one bad cell to make it pretty much worthless, Plus the alternator is being over worked trying to charge it as it runs the car for you after starting,, ( note, never disconnect the battery when the car is running to check to see if the alternator is working, that will result in bad problems , such as computer stoppage) once your sure you have a fully charged, good battery in place, use a volt meter to check ,, start the vehicle and place the meter probe's on the battery terminals,, you should get a reading of no less than 13.5 volts, and should see that up to 14.5 volts on the meter, if you do the alternator is doing its job.

Brake and Batt warning lights on at same time while engine running. Brake fluid is max and alternator belt looks good.


1st clean all the battery connections,, it appears whats happening is that the alternator isn't being able to charge the battery after a start , normally a good cleaning will do the trick, But your battery could have a bad cell too, Just because a meter says 12volts, doesn't mean the battery has the amps it needs, so have the battery charged, then LOAD tested, any parts store usually can do this for you . once charged, and with a meter connected to the battery terminals, you should get a reading of 13.5-14.5 volts, if not, you have an alternator issue,, unless the brake pads are worn excessively, correcting the battery issue most the time will also clear the brake light

Sounds like the alternator......If you have a auto parts chain store near you they will check the alternator for you. Autozone or similar store will do it for free!
