I already changed out the battery twice hoping I just got a bad battery from the store. No luck. Still doing the same thing. I'm wondering if it could be the alternator pulling power off the battery overnight. Should I try changing this part since there really isn't much that could cause this draw?

Truck is a 78 chevy k-10
