There really is no good way for the consumer to trouble shoot the elctrical system. From what you describe the brake switch is working it is providing an on and off.
You will need to get this to a local authorized Husqvarna service center and they will need to find the draw on the battery as well as the electrical failure, most likely cause is the key being left in the on position. Make sure to tell the dealer of ANY parts that have been changed on the mower like the key switch or PTO switch.
