Why is your 2002 Tahoe battery going dead after changing the battery and checking the alternator?
First check to see if all accessory lights, such as glove box light, under-hood light etc turn off when compartment is closed. If you want to rule out an chance of a faulty alternator diode simply disconnect alternator output cable and regulator connector at the alternator and leave the vehicle overnight to see if this changes anything, if that does not solve it, disconnect the battery ground cable and between the cable and the battery neg post connect a 12v light bulb such as an incandescent test light. bulb will light if there is a drain. start at fuse box and remove fuses one at a time watching to see which one causes the light to go out. this will be the circuit that has the problem.
