1997 not wanting to stay running
Hi guys, I am new to this forum and am on my first Jeep. it is a 1997 Grand Cherokee Limited with a 5.2l v8. I love the car but........ I am having my first problem with it.
So the battery was dying after sitting for a few days. when i would jump it, it would fire right up and things would be good. Them just recently the battery died again. so I i tried to jump it and it would fire up but it wouldn't stay running. I tried it again and this time i put my foot on the gas and held it at 1500 rpm for a bit then let out and.... died again. I put a new battery in it and it fired right up but guess what...... died again. I read online that it was maybe my alternator so i took it off and took it to my local auto parts to get it checked.....but they ran it twice and it was good. I for sure need a new battery but I have no idea what could be causing this. I was hoping someone here maybe experienced this problem before and could help me out. I know I should take it in but I am a little strapped for cash right now so I am hoping one of you can help me out with some trouble shooting.
Thanks in advance for your time and help.
