    Default '99 Silverado Battery drain after setting several days

    Looking for a possible bulletin or related problem with my '99 Chev Silverado. The battery charge is draining after setting for several days. Battery is new, 3rd within a year. The only thing using electric after shut-of is a diode in my, "Brake Force" trailer brake controler, which is aftermarket and has worked great for 3 years.

    Hi, and welcome to the site! Glad to have you here! Are you pulling a trailer everyday? If not, try disconnecting the brake controller, and see if it still does it. When I bought my Tahoe the vanity mirror was broke on the passenger side, allowing the lights to be on all the time. I happened to see it one night after I locked it. I fixed it, and my battery has been fine every since. Hope this helps. Good Luck!
