96 K1500 Suburban Slow Drain

    I have a 96 GMC Suburban K1500 and I have a battery drain. Has anyone else had this problem and how did you find/ fix it?

    The truck runs great but if it sits for a few days the battery is dead. It jumps fast and easily.

    thanks,
    Dave

    Simplest way to find the current drain is this: disconnect the negative cable from the battery, and jump from the cable to the battery with a test light - it should light up if there is a drain. If so, start pulling fuses 1 at a time until the light goes out. When it does, you've found the circuit in question.
