Question about Cars & Trucks
Hello Just a hunch but before you started replacing everything did you test the alternator for proper voltage and now with the new one in with vehicle running what is the voltage? The reason i ask this many people just start replacing parts for no reason ! might not have ever been the charging system or battery, If the lights are staying on there is a reason. What i do is test engine running for the voltage at battery should be 13.7 14.4 somewhere in there, if not then that's where the problem is. if voltage is good then check battery disconnected for voltage- then a few hours later or get it load tested-if all is good with battery then now we check for short and a draw on the battery.This will take time but no cost. use volt meter reconnect battery and make sure vehicle is not running doors are closed if possible and watch the voltage drop to kill battery as u pull fuses one at a time-reason for this is to see what fuse is running what is drawing the power, once you know then you can start checking what is on that fuse and trace the short

May I suggest that you drive your car to one of the major auto stores and they can and will check your alternator for you to make sure it is good/bad.These places like AutoZone do this all the time. They do not charge for the check out. (Of course they are hoping that if you need a part you will buy it from them.
One other suggestion. If you do need a new alternator, get a rebuilt one. It is cheaper and most always comes with a warranty.
Hope this helps Good luck Loringh PS please take a moment to give me a rating

Check all your fuses if you had a system failure it could have blown a fuse. I am not sure on your vehicle where the fuse is in the car or under the hood it could also have a relay. You can check your alternator by checking the voltage at the back of the alternator where the big wire bolts on. You should have 14+ volts at the alternator.

Check the main power fuse that goes to the alternator output. if the alternator went out it could have burnt this fuse also.
