2001 Chevy Tahoe

Got a question for you guys, Why does my battery keep draining itself down I've got a brand new alternator on it and the battery keeps draining itself down?

Must have a parasitic draw coming from somewhere. How long does it sit before the battery dies? Overnight? Takes a week?

Overnight but can jump it off and it'll run fine the next morning have to come out and jump it off again.

Went and bought a Battery Relay Switch for my Tahoe and it stopped the parasitic draw....
