Hi, I bought this car, And the first day I got it the battery went dead. So I charged it up and it went dead again in six hours. So I figured the battery was bad, so took it up and got a new battery, two days later that battery is dead too. The only thing I could tail is the glowing from above the radio that has the weather and time clock on it, so I disconnected the radio fuse and the battery doesn’t go dead anymore. How do I go about finding where the short is for this or if there’s a problem with it? Does anybody have a diagram of the electrical going from the radio to the fuse? Thank you everyone

 

Some newer vehicles have several modules that make up a "Network". If something is preventing one of these modules from going into sleep mode it will prevent the network from going into sleep mode and will continue draining the battery. The radio in some vehicles is one of the modules. The best way to check this out is with a capable scan tool that can check module health. It should be able to tell you which module is malfunctioning and it could be the radio itself or it could be something keeping the accessory delay circuit active when it should be shutting down after the engine is shut down.
