went out to start my elcamino a minute ago and the @#$%^&* battery is dead. it is the one out of my blazer. it died while i was doing some 4 wheeling. i was able to jump start it to drive it home and move it around the yard. i swapped the elcamino battery for it, now i cant even jumpstart the old battery. it kinda p*ssed me off because i really wanted to hear my elcamino run.
