The procedure to replace alternator is as follows:-- 1) Determine which alternator your Toyota Corolla needs. Be sure the new alternator is compatible with your Corolla's engine.2) Disconnect the negative battery cable with a socket wrench. Remove the gravel shield if you need to access the alternator from under the car. Remove the electrical connector and unfasten the retaining nut on the alternator terminal with a socket wrench. This allows you to remove the battery terminal wire.
Remove the drive belt. Unfasten the two mounting bolts on the alternator with a socket wrench and take the alternator off the vehicle.
Install the new alternator assembly. Use a torque wrench to tighten the smaller mounting bolt to 18 foot-lb. and the larger one to 40 foot-lb.
Connect the electrical harness and battery terminal wire to the alternator and fasten the retaining nut to the alternator terminal with a socket wrench.

2010 corolla not charging replaced altinator and fuses and battery still having this problem

Hi. There are four things to look at. One of the four will be the issue. Check for ground at the alternator. Check for battery power at the alternator's main (+) battery terminal. Check the field for 12volts (Key On). If these three tests pass you will need to remove the alternator and have it bench tested. This should help. Please let me know if you are still having an issue. Good Luck.

If you have a good battery that dies. It would help if you had a volt meter to see how many volts your battery has and if you could get it to start, check the volts on the battery while its running. 12.4-12.6v while off is good. 13+ volts while on is most likely a good alternator.Another thing you can do is take the alternator to oreillys or another auto store and they should be able to test it for free.

My dashboard battery light is illuminated/i replaced the battery but light is still illuminated??

The battery light is not an indicator to replace the battery. It is an indicator to tell you that your alternator is not producing sufficient voltage to charge the battery. If you have a Delco alternator, you would be best advised to replace it. Those cars were notorious for bad Delco alternators.

Replace the alternator, and you should be fine.

Thanks for choosing FixYa for advice!
