1994 olds battery draining

We have replaced alternator, starter and battery and still something is draining the power from the battery. It doesn't happen every night but it is getting old. Any help would be appreciated

Welcome to AF drrussell !

It helps to know what your engine is... :grinyes:

So this happen all the sudden, or just after you started replacing things?

Have you recently installed any thing electronic?

Check that all your cables are clean and tight.
Even on the starter cable, and engine grounds.

Check the wires on the Alternator plug and the hot wire.
Kinda check for broken wires there.
