My Hyundai Tucson battery is draining daily.
I found that it has to do with the fuse associated with the alternator; if I pull the fuse at night it does not drain the battery. I have changed the alternator and computer, but did not fix the problem. Any suggestions.
If you have replaced both of those then the only other option is a wiring problem.
This might be the same issue I'm having. Do you notice that when you open the car door after turning the ignition off and removing your key that the warning alarm comes on. Same alarm you hear trying to exit the car with the key in the ignition. If so, its an ignition switch issue. This drained my battery a few times before I figured it out.
