We need to start by doing a voltage test do you have a multimeter to do some testing?Sounds like you could just have a bad alternator.
The battery light is on when at idle and its running bad two things that point to a bad alternator. If it was just the battery light on I would say may just a fault in the battery light circuit. But with the other symptoms I really want to know at idle what the voltage reads at the battery when the battery light is on.
When started it idles between the 1 and 0. And battery light on. If I give it gas light turns off. If I don't give gas truck dies
Also he said he could be a vacuum leak. Does that sound familiar. I just had to replace that last summer. Kind of getting the same symptoms but last summer the battery light didn't come on
I dont see how a vacuum would cause the battery light to come on?The first thing I would do is what I told you to do with the voltage reading. That is what I need you to do and give me the results?I have been working on cars for a long time now so when I ask you do something I need you do it. Because I cant do it for you so please let me help you and make it easy as possible.
Ok no problem. I appreciate Your help. I am single mom so I have to do it myself. I am not understanding what you mean by what the voltage reads. Do I need to look at the battery when I start the truck
To read the voltage you will need a multimeter/volt meter to read the voltage. You dont know anyone that knows how to use a volt meter?
How do I replace a battery in a 2009 Chevy Equinox LS with a 3.4L V6. Most cars are straight forward, this looks difficult. Shame on GM. Thanks.
