My names Chance.

Thank you Chance. So the battery dies when the vehicle is sitting overnight? Would you like a test to help pinpoint the root cause of the battery draw?

That's what it used to do. It starts now but the charging system battery light is on.

What is the battery voltage at idle?

Last time that happened my AC stopped working.It's around 12I got the battery starter and alternator all changed too.But it still says charging system battery.

can you speak on the phone?

I cant pay that much money to speak on the phone so no.

Ok no problem. You need to check all fuses and all inputs to the back of the alternator to ensure there is no circuit issue. If all checks out good, you need to replace the alternator under warranty.

When I got the car it would need a jump to start. Went to the shop they said it was the battery and starter. I got those changed. Got the car back and that's when the charging system battery came on. I took it back to the shop they said it was the alternator so then I got that changed. I got the car back and it still had the light on.

You need to have them check the inputs to the back of the alternator to determine why the new alternator is not working.

Even before I got my keys back they told me the light is still on so they really didnt do anything to help meI know where the alternator is so how do I know what is what and if it's good? The fuses and inputs.

I would agree. There is a fusible link coming off of the starter that provides power to the alternator. That could be bad preventing the alternator from charging. Also, the computer controls the alternator so it could be a computer issue as well. They need to check for codes in the computer as well.

Can I go to autozone or something and have then scan it?What color is the fusible link. Black?

YES, if your vehicle will run long enough, you can have it scanned at your local auto parts store. YES, I do believe the fusible link will be black in color. It has been a pleasure working with you so far. Keep in mind this is a “starting point”. We can always continue as needed at a later date or at any time. Feel free to run some tests and reply back for further assistance as needed. Glad I can help. Please let me know if you have any further questions. Thanks and have a great night!

If I need to contact you again do I just reply to this message?

You got it!

Thanks. I'll be in touch.

You are most welcome!
