Something is draining the battery on our 2002 bmw z 3. The battery and alternator checks out good. What could be the problem??

The problem is that an electrical component in the BMW that should be dormant when the vehicle is shut down is actively drawing power.
The only way to track it down is to have tests run to see which circuit is drawing excessive power because there are numerous components that might be the cause.

Electrical battery drain OR "parasitic drain"

Seen this "mystery drain" many times. Check spark at the battery to see how big the drain is. For this simple test, blow away any (explosive) battery charging fumes. Leave one terminal on and gently touch the other to its post in fairly dark surroundings. Then try it again with the wires taken off the alternator. Your spark is now probably much less. Usually bad diodes leaking electricity backwards through the alternator cause this drain. Replace the alternator or the diode pack inside it. Some mechanics recommend actually measuring the drain.... hahaha. OK whatever.

2008 camry battery drain excessive drains battery

Hi my name is Tom and I can help you.

Most battery drains are shorts in the electrical system. Also, you might have a light(such as a dome light or trunk light that is not turning off.

Electrical problems are the personal hell of mechanics because one wire touching the cars ground and you have a drain which will drive you crazy. If you have the time you can check all the wiring on the car, if not take it to a shop. They will spend hours finding it and never can charge you what it is worth.

Battery draining when engine is switched off

The negative terminal is the earth
The larger cable is for the engine earth so the starter will work, the smaller one is the body earth, The car needs both for the electrics to work, If you disconnect the small cable the electrics may earth back through somthing else like the throttle cable and this will not stop the battery drain

Have tried 2 new batteries. car starts at once. runs smoothly. but when ignition is switched off for about 30 minutes, the battery goes dead! The alt. has been checked OK. The problem started when we...

The cause is most probably a current drain on the battery when the vehicle is switched off.

Check for a drain current from the battery while the vehicle is standing with engine and all electrical system turned OFF -
[ while in this condition, if you don't have a current meter, temporarily connect a small bulb (6-12W) in series with the main battery ground cable - lamp glow indicates current drain - remove fuses, disconnect items to identify cause of current drain],

Also check alterator output voltage (measured across the battery terminals) is approx 14.5V when engine is running and electric system is loaded with headlights or blower fan on.

Battery will drain if left connected overnight

your problem is faulty electrical, you have to trace your electrical wires for a shorted line or an electrical component is always on causing the draining of the battery.
