Had the same problem, changed the positive and negative battery cable heads, this stopped the drain. Check and see if the cables are good first.
A battery cannot be drained by a shorted diode when the ignition key is off.
usually means that the alternator is not charging. So the battery is being drained.
Yes, a starter solenoid can drain a battery. When a starter solenoid is not working properly it can actually keep rotating the starter after the car's ignition is turned off. Since it requires a battery to actuate the starter, the battery will eventually be drained of power.
The ignition switch generally has four positions: off, accessories, on, and start. Some cars have two off positions, off and lock; one turns off the car, and the other allows the key to be removed from the ignition. When the key is turned to the accessories position, certain accessories, such as the radio, are powered; however, accessories that use too much battery power, such as window motors, remain off in order to prevent the car's battery from being drained. The accessories position uses the least amount of battery power when the engine is not running, which is why drive-in movie theaters recommend that the car be left in the accessories mode during the movie.
Your alternator has failed, and the battery has drained from running the vehicle without being able to recharge it. Replace the alternator and the battery should be fine.
