Dear, I have a 2002 4 door Chevy Blazer and I have a big problem with the electrical system. From now I say it's not the battery, this is new and was tested and is OK, the battery will discharge 2-3 days this means that there is consumption of "something" in the Blazer. 2 Electric have seen and have not seen what they consume electricity.

Questions .... Has someone has this happened? Someone knows it can be?

Thanks.
