With key off, remove neg batt cable, and put clamp on cable end, and probe on battery neg post. Light will be lit if you have a drain. If light is on, start unplugging fuses one at a time, and when the light goes out, you've found the particular circuit your drain is on. If you pull all fuses and still have a drain, try unhooking your alternator and see if it goes out. My drain was a bad diode in the alterntor that was draining the battery.
