My 1990 Chevy 1500 keeps blowing batteries and i would like to know what would cause that
First thing to check would be the alternator, it may be over charging them.
Get a free diagnostic done on the alternator at Auto Zone.
Next check the would be the cables. Make sure all you battery cable connections are secure and corrosion free, especially the ground points.
