short? or somthing ealse. flat battery

Again mate, its not a short. A short is a direct connection from power to ground. A short in a small AA battery would not be noticeable, but a battery that big would be noticed within seconds. A short would blow fuses, make wire incredibly hot and possibly cause the battery to explode.

OK - last thing you haven't done is to connect an ampmeter or multimeter to the battery to discover just how much power is being drained from the battery when everything is switched off. You said initially there is a big spark when you dis/connect the neg terminal - you need to verify if this big spark is simply initially charging a capacitor or is a constant current drain. Only way is to connect one of the above instruments. If the drain is more than say 500 milliamps then you have something that is running all the time.
