Hello, Im Leann and i drive a 96 Tahoe. I have recently had a problem with battery draining out in 24 hours. I have replace my starter, altanator. ignition switch, and starter relay. I have a 10k watt system in my truck and have been told that its staying on after the truck is off. Right now when i try to crank the engine over i just get a clicking noise. Im not sure if this is my total problem... I have also replace the battery and tried to unhook the system, but when i do that i dont even get the clicking noise. please help

 

You must have unhooked something in the starter circuit. It sounds like something is staying on to drain the battery. It is more than a small light as that would not drain a good battery overnight.

 

Sure it isn't just a bad battery?
