Alternator out-put

Hello, Danny here.

That is way below specifications. It should be closer to 14.5-15 volts.
You need to replace the alternator. I have attached an alternator replacement tutorial. Hope this helps and thanks for using 2CarPros.

Hi and thanks for using 2CarPros.com.

When testing, you should. That way you place the biggest load on the system. If it is going to fail, it will then.

Here is a link that shows how to check an alternator. See if it helps.

If you find it difficult to check it yourself, most parts stores will do it for free on the vehicle. However, if the vehicle is not running, remove the alternator and have them bench test it. Same thing with that. Most do it for free hoping to sell you a part.

Let me know if this helps or if you have other questions.

Take care,
