Question

drains battery overnight...

Answer 1

Hi there

This is called a parasitic drain. This is difficult to locate, but I would start by removing the under hood light. You need a volt meter to test for the drain. When you see the voltage on the meter, basically you remove one fuse at a time until the voltage drops, once it does, then you have to check everything on that circuit to find the short.
