My 1998 Chevy Silverado K1500 truck is sucking the battery dry. I just replaced my old battery with a brand new Die Hard Gold. After sitting in the garage two weeks it has been drained. I didn’t have anything turned on in the truck, I checked lights, open doors, open hood etc…. nothing left on. The last thing I repaired on the truck was the dimmer switch from O’reilly Auto parts BWD dimmer switch.
My question here is where do I start and how do I start finding what’s draining the battery while the truck sits?
Thank you,
Ryan

Do you have a Multimeter? Attach a multimeter up to your battery (after you have it replaced/recharged) and check for the draw. Then go into the cab, and start pulling fuses one at a time, until your draw gets down to acceptable levels. Then check what that fuse was for. Thats how you’re going to need to start.

Sounds like a parasitic draw on the battery. Was any work recently done, or maybe a fender bender?
You could try to get a 1 ohm 10 watt resistor, and connect a wire with cliips to both sides of the resistor. Disconnect the negative battery cable and clip one end to battery neg cable and connect voltmeter to neg bat terminal and other lead.With everything off you whould read about 35 to 45 millivolts, If not pull one fuse at a time until you get that reading, and when you do,that will be the circuit to check,
