SOURCE: replaced alternator and battery is good but not charging

I found the problem YEAH. It was the fuse that is in the side of the fuse box under the hood, Its where the battery wire from the alternator connects thru a fuse to go to the battery, Its one hundred and something volt fuse. It took care of the problem instantly.... Thank you all for your replies...

SOURCE: the alternator is good, new battery , wont stay

Ok, i understand that you have replaced the alternator, but there seems to be a non charge state in this case. i recommend checking the charging system. use the procedure below to isolate this issue.

Wear protective eye wear and clothing and remove all jewelry when checking your battery and charging system. Jewelry is a good conductor of electricity and is not recommended. Most batteries wear out every 3 to 5 years and need to be replaced. Always replace your battery with an equal replacement battery to assure proper operation. Automotive batteries have a +positive terminal (red), - negative terminal (black). The battery in this illustration has a protective cover over the positive terminal to prevent short circuit in case of an accident. Electricity is stored in the battery and then supplied to the vehicle when the engine is not running. While the engine is running the vehicles alternator charges the battery for future use. (Note: never disconnect the battery while the engine is running. If the battery cable is disconnected from the battery a spark can be generated which can cause the battery to explode or a major electrical malfunction to occur.)

To check a battery surface voltage, remove the positive terminal protective cover. Connect the +positive side meter lead (red) to the positive side battery terminal. Connect the - negative (black) side meter lead to the negative battery terminal. With the vehicle not running and the car sitting over night the battery voltage should be between 12.5 and 12.8 volts.(You will need to use a voltmeter for this testing procedure)

The alternator is rotated by a drive belt driven by the vehicles engine while it is running. Electrical voltage and amperage are generated to recharge the battery and supply voltage to the electrical system of the car. The alternator is held in place with mounting bolts. There is a main electrical wire on the rear of the alternator that supplies voltage to a main voltage junction box. If your alternator is not charging properly, your battery will slowly drain down from operating all the electrical systems in your car and stop the car from running.(most non charge states will be the cause of a loose belt or a low tension rate, due to a mis-adjusted alternator. make sure you have enough tension in the belt for full rotation of the alt pulley)

Next, you will need to check the alternators output with the Amp meter.

Testing the amperage output of the alternator is good for measuring the amount (not the level) of voltage the alternator can produce. This test can be tricky because if the alternator is weak it can still show it as producing amperage. Which is good, but if the voltage is low, it will still allow the battery to go dead. To check the amperage output of an alternator an amp meter is needed. Once the meter is connected start the engine. Next turn on all electrical accessories and raise the engine idle to about 1200 RPM. The alternator should output the max amperage it was designed to produce. Example: a 90 amp alternator should output about 88 amps. Note: An alternator cannot sustain maximum output for long periods of time. If the alternator is forced to operate at maximum output it will overheat and fail. An alternator is designed to operate at max amperage output only for a reasonable amount of time.

((Connect the voltage meter lead the same way you would in a battery static voltage check, Start engine (do not drive) at engine idle the voltage should be between 13.6 to 14.3 volts. If not the alternator may need replacing.)))

Replace the large wire on the back of the alternator,with a new one,it comes off the back to the positive side of the battery,leave the old one on the alternator.

Battery light stays on after changing battery,alternater & plugin.


Is the system charging? You should have 14.2 14.6 volts at the battery. The charge light is controlled by the alternator internally. If the charging system is working, you could have a bad diode inside the alternator keeping the light on or a short/grounded circuit to the battery light

I have 05 kia rio. jump started dead battery but the cables were crossed and killed it instead. purchased new battery. car stuck in park. worked when screwdriver in override button but still won'


There is a large maxi-fuse between the battery and alternator. Its at least 100 amp or more. It may be in the cable at the battery, or in one of the fuse boxes.
You may also have damaged the key switch or the brake circuit.
You may have to get a book to get the wiring diagrams to check everything involved.

Battery won't stay charged, it is brand new battery, alternator has been checked and it is good, blown BTN 60 watt fuse, on 1994 Mazda Protege.


The 60amp fuse probably is in the circuit between the alternator and the battery. Which would be why the battery is not getting charged.
Someone would need to check for a short in the wiring between the alternator and the battery.

You might have a bad alternator. Take your battery in to have it tested and if it is good then it is probably you alternator. Good luck

2000 lumina' new battery won,t maintain a charge


Have the charging system load tested and make sure the alternator is charging.If this is good then you will have to check for a draw.If you have anything that is staying on and draining the battery or if you have something plugged into the accessory plug that could be draining the battery.You can check for a draw with a multimeter but this is a little more complicated if you are not familiar with this process.Hope this helps.Good luck.
