Battery light on

With the car at idle and the battery light on tell me what the voltage is at the battery?Sounds like a alternator going bad. Some die slow and some go suddenly.

The voltage when the car at idle and the battery light is on is 14.7 volt. The guy at oreilly is used to be a mecanic he checked the alternator and the battery. He told me the alternator is good he tested it under load headlight on and I gave him the battery he put it in the charger for 10 minutes he said the battery is holding the charge

Hi,
about two days ago, my battery light went on when I was on an incline. I went to my mechanic who tested the battery and said it was charged. We turned the car on and off a few times and nothing. Then the battery light went on again later that night. I rinsed off some of the corrosion on the battery with water and it was fine for a day. Then, when I was going up a hill yesterday, the battery light went on again and has stayed on since - the cable connecting to the battery seems firm and only one of the cable attachments to the battery has corrosion - what should I do?

If the battery is in good condition with clean and tight posts/cables-have the alternator load tested might not be putting out or the battery is not taking the charge.

The battery light is on. Today I replaced the battery and the battery light still on.
There is a DTC code p063a generator voltage sense circuit. The alternator is generating 14.5 volt when the car is running and under load

what could be the problem
thank you

This is a very common issue on that particular vehicle. There is a T.S.B. (Technical service bulletin) pertaining to that exact issue. The t.S.B. Number is 18-007-07. It requires updating and/or reflashing the pcm. Call you local dealer and ask them about the t.S.B. Number.

I have a DTC code P063A.
Battery and alternator are good.
I hook up a voltmeter to the battery car and drove it the battery light came in when voltage was 14.3 volt

I saw a service bulletin related to the p063A code as well as other code. It was listed under driveability improvements. You reflash/reprogram the computer. You may need to take it to dealership? The ref number for the bulletin is 18-007-07.

I have had the battery and alternator checked they are ok what should I try next

Hi:
If the alt light is coming on from time to time, I say the alt is the problem. When it was checked, was the light on?

Joe

No

You need to have it checked when the light is on. My guess is that it's going bad.

Thank you it was a bad alternator

I have had the battery and alternator/genorator checked and everything checked out ok so where to I go from here?

Chances are the alt is on its way out. However, when you have it checked, it is working fine. I would think it will progressively get worse to a point that they will be able to identify the problem.

Pam, if you have other questions let us know, and I would like to kow how you make out with this problem.

Joe

OK Joe I will keep you posted

I m looking for electrical diagram for the battery light.I want to check the circuit if it shorted

Thank you

Let me ask what kind of issue you are having. Maybe we can help you with it.

The battery light comes on and after I turn off the engine and restart it it is not on anymore it does that every day so I think my be there is a short in the circuit
