I got a new battery and alternator that tests good but after sitting for awhile I still have to get jumped off and don't know why or what to check....HELP ME PLEASE!!!

 

Can you go to an Advance Auto store and get them to run a full charging system health check? They do it for free. I've had a full check find issues.

 

Is ur brake and battery light on?

 

You may have a large parasitic draw. Google how to check for that using a multimeter connected to your battery. My moms car had the same thing and it turns out the sun visor mirror had a light on it and even tho the the lid was closed the light was still on underneath slowly draining the battery and after a few days of sitting (she has 2 cars) it would not start without a jump.

 

No

 

I had the battery and alternator checked. Do I just ask for a full system check??

 

How did you fix it. My visor doesn't close all the way. Its a slight gap but I can't see any light

 

If they do a full system check it looks for parasitic drains when the car is turned off, too much draw while the engine is running with lights and A/C on and etc.

 

it could be a parasitic draw but it dies after a few hours so the likely hood of an interior light depleting the battery is very minuscule. check the altinator belt, the battery could possibly not be getting a strong recharge which might be causing the frequent dead battery situation.

 

+1 on the parasitic draw.

Youtube it. Very simple. All you need is a multimeter...
