Hi I have a 97 STS I am trying to get it running. I charge the battery and reconnect it to the system, the interior lights, and radio come on. As soon as I turn the ignition switch to the on but not start position, the power drains out of the battery, and the inadvert power relay starts ticking. My code tester cannot read the car because the power is to low, all of this in less than 3 minutes. The battery is less than 1 yr old but was 1/2 dry before I charged it. The battery before this one tested for a dead cell while still under warranty. I dont have a clue what to do. Please help thanks Rich

Rich:
Remove the battery, fully charge it, and have it load tested at a parts store to see if it is good. It is nearly impossible to kill a battery that fast without causing a fire. Another thought would be to make sure the battery terminals are clean and tight. If one is slightly loose or corroded, usually you will get a click then lose power.

Let me know what you find.
