ok the truck i have runs just fine until the next morning the red light on the dash is blinking and the truck wont start i just jump start it and its fine but every time in the morning i have to jump start the truck again i tested the battery and alternator and starter they all check out fine.

 

Replace your battery....it is obviously bad or you have one HUGE power drain somewhere

 

Yep battery is going. Time for a new one

 

ok i will replace it and see it that fixes it but auto zone said the battery was fine when i tested it a few days ago

 

They are not always correct. But then neither are we. Flip a coin and decide....

Seriously though, everyone that comes in here with a red light blinking has had a bad battery. That why we say swap it out.
