I need a lot more information from you to help. There are a number of unknown potential reasons the battery and charging system are still not working. More than likely the new parts are ok but you can not assume that they are. Suspect everything. Do you have any test equipment to check the battery and charging system state? I need you to charge the battery back to 100 percent. We don't know if there is a short or parasitic draw so disconnect the battery before charging. After the battery is charged *BE CAREFUL*. Have safety glasses and water readily available if the battery explodes. You need to quickly wash the acid off your body. Note: Immediately wash your clothing or just throw them away. Battery acid will ruin clothing if the acid isn't diluted soon. I'm a master mechanic. In my life so far I have had two defective batteries explode in my face. Thank GOD I was wearing the safety glasses. Now load test battery. If not possible, hold off and temporarily connect the battery terminals. Connect the positive side first then momentarily connect the negative side. Was there a big blueish wight ark? If so, remove the terminal for a breif second and reconnect the ground again. Did it have the same big large ark or was it mild or tiny this time? If the spark was mild install both battery terminals and tighten. Start the car verify that the alternator is charging. What is it charging at at idle? At 1500 RPMS? What is it charging at with the heater on (At high speed) and high beams are on too. The alternator should support the system between 13.5 to 14.5 volts. Run your tests, write down your results and let me know if you are all set or need more help. Good luck.

You have already figured it out but don't know the answer <(^_^)> . It's the alternator.

SOURCE: 2001 kia rio checked battery

After disconnecting the battery overnight does it hold its charge? if not, its the battery. if it does then you have something draining it and this could take a bit of finding, is the radio draining it? you might think its off when it not, remove the fuse for the radio and try again. Have you got any mobile phone in car set up fitted? this is also a favorite for draining the battery. It has been known for the alternator itself to be faulty but as you have had this replaced with a new one, you can rule this out for now. interior lights is another possibility (the dim feature if fitted) or if you have a light fitted in the boot or bonnet, (trunk or hood) removal of fuses one component at a time should help you in pinpointing the culprit, but as I said if you know the battery is fully charged, disconnect it overnight and see if it is still charged in the morning when you reconnect it. There are other ways to find the problem but unless you are an auto electrician there is no point in telling you as you wont have the equipment to use, that by the way is your final option, take it to an auto electrician.

SOURCE: 2003 kia sedona wont charge battery with new alternator

well are you sure that you have a good or it just shows the correct amount of voltage. which that should 12.6 volts for a fully charged battery. to actually answer your question, (assuming)
you do have a good battery your alt. shouldn't keep it from cranking unless it is locked up, but you would use a digital volt meter and select the d.c. volts setting touch the red (positive lead) to the red (positive post) on the battery and the ground ( black lead ) to the ground terminal on the battery (negative post). it should read very close to 14 volts. if not check to see if you are getting voltage to your alt. by using your volt meter to test the power wire going to your alt. it will be the one on the backside of your alt with a protective boot over it. with your volt meter still set on dc volts touch your black lead lead to a good ground and your red lead to your power wire going to your alt. it should have 12 volts there. if not check your fuses. if your car clicks when you try to start it then you may have a bad battery connection. dirty terminals with corrosion built up on them will do the same thing. also a starter that is bad will click because the bendix can't kick out to engage the flywheel to turn your engine over. well hope i answered your question and then some.

I have an 01 kia rio that seems to be having a problem with the battery holding a charge, battery, alternator, and even the starter are all brand new. Everything will run fine for a day or two then I

place an amp meter in the circuit of the battery earth wire and get an idea of what the current draw is so you can have an idea of what piece of equipment is using the power. Radio amps require a big draw where glove box light, boot light, interior light are small draws. If it shows a medium draw the pull the ECM fuse, or IGN fuse or light control module fuse to see if the current draw drops . Even new alternators can be faulty especially if the unit was not wired up correctly and blew a diode. All it takes is a simple touch . have an accredited auto electrician check it out on the bench

2005 Kia Rio - sometimes won't start, but has a new battery

I once had a chvy lumina car that had a similar problem. I ended up replacing the alternator that was not charging up the battery. The battery was replaced first and then the alternator. In addition, the electronic motherboard was replaced underneath the coil pack. I did all the work myself. No more electronic problems. If they did a diagnostic test on your car and it showed a bad battery then the battery should be tested by Autozone. Go to Oreilly's too for test.

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.
