Start with checking the condition of the battery, be sure it is fully charged. Cables clean and tight. Also have starter and alternator checked, they might have a short that is draining the battery. After that if you haven't found the problem, you can take the negative cable off the battery and attach a test light to the neg cable end and the other to the car body if the light comes on you have a short. Remove fuses one at a time until the light goes off. Then check everything on that circuit, that is where your short is.
