So last week I proactively installed a new battery after my power steering/alternator belt broke.
Well later in the week, my door locks stopped working from inside...I'm thinking door lock timer gone bad? Needless to say I didn't check it, but let the car sit for 2 days without driving it. This morning the car completely dead, won't even crank.
Can someone tell me how to check for an electrical drain somewhere in the car? I wouldn't think it's the battery but not sure.

Thanks
