i have a 1994 dodge dakota sport. 6 cyl.

my battery keeps dying, but testing says its good.
testing also says my alternator is good.

any help?

thanks

 

Sounds like you have some kind of drain on the battery. Like a light on or radio on when you leave for the night. You might want to disconnect the battery over night or how everlong it takes it to drain. Then hook the battery up then see if it starts. If it is still dead you will need a stronger battery. Also by dieing do you meen its completely dead or just somepower and not enough to start the truck. Because your starter may be going out and requireing to much power. If you know how to use a amp meter you can pull out fueses and see which one is pulling power when the key is off.
