Battery drained

Asked by Sep 23, 2016 at 09:17 PM about the 1990 Chevrolet C/K 1500 Standard Cab SB 4WD

Question type: Maintenance & Repair

With a brand new battery and alternator, my battery will
slowly drain down until I have to jump it to start it. Twice
now I've replaced both batt and alt which lasts for a month
or 2 then slowly i can tell the battery is losing its charge. My
biggest problem is that it's not just drained and that's it.
Every time the truck sits for an extended period of time,
such as overnight, the battery seems fully charged and
starts just fine but if I drive to the gas station and shut it off
then the restart seems to lag until one day it has drained
the battery too much and then I need a jump.

What about the Battery terminals & terminal wires, and ground to frame from battery and block to frame ground? May also have a voltage leak due to a wire shorting out, or a bad connections somewhere. Connection at starter check it, Starter May be showing early signs of failure and showing this when its hot.
