My battery was not charging so I had the alternator replaced 6 months ago with a 'rebuilt' one. It was fine for 3-4 months. Then the battery light came on again, tester showed 10.5 V and the starter was very low. I got a new battery. The shop wanted to sell me a starter, but I did not believe that I needed one.
Two months later, my battery light came on- stayed on- but the car restarted fine. The tester checked it for 12.5 V, it was low.
I only drove about 15-20 miles. The shop refused to warrant the battery, because I did not want to replace the starter.
1. Should I check out the alternator again for problems
2. Do I need a starter?
I have 2003 Hyundai Sonata, a great car besides this problem.
Thanks, in advance!

Look like the mechanic (or the guy who work on your car) didn't know what he is doing.
Voltage test of battery and charging system is not a good test to show how good are the battery and alternator and wiring.
You need a load test of battery and charging system.
One of the tester i know is very good and does all the test automatically is Midtronic Incharge 9 series.
I would find other shop for your car problem.
Your Sonata alternator output rate is about 95A.
The Sonata charging circuit is very simple. If the fuses (2) and wiring checked OK, i think your rebuilt alternator is bad. Make sure you get one from dealer only. Do not use aftermarket rebuilt.

I am very sorry for your problems and the dubious answers you have gotten so far. if you can, charge teh batt and measure the current your starter draws with a clamp style meter it should draw less than one fifty amps if if does then its not the problem and you should look at the alt again. good luck!

First ck. the voltage at the battery without the engine running. If it reads anything over about 12.5v your battery is fine. If it reads lower than that it will need to be charged and retested. If it is reading proper voltage then start the car and recheck the voltage with it running. The average "healthy" alternator output should be somewhere between 13.1-14.6v depending upon demand. Once the battery has recovered from starting the engine the output should be at least 12.9-13.1v. If it does not do this then your alt. is suspect.

Typically Hyundai's are one of the worst cars you can get. they're full of engineering faults. anything that young (2003) shouldn't be having problems at all. Tip for the future- don't buy another one. Try and stay close to Toyota's.
Because your problems are engineering faults and not your typical wear and tear you would be best to go to an Auto Electrician. take a male with you.. you are less likely to get ripped off.

I don't know where you are but they are giving you a crock. Where did you buy the battery? I do not believe the starter would be the problem. Consider that you use the starter for mere seconds to start the car.
Since you replaced both the battery and alternator, I would make sure the ground connections to the engine and or chassis are clean and tight. This is often overlooked and can keep the battery from getting charged properly.

Check to see if your wiring harness is all tight

Sounds like it a defective alternator just take it back to the shop it should be a warranty atleast at ours it would be.. If you had a friend do it or something have them remove it take it back to the parts store and let them know.
