hey mate i am not in brissy, im in sydney.
just subscribe to my thread and i will repost with whether or not the battery is still being drained in a few days to see if i have narrowed the problem down to the rear wiper / not.
Hopefully the battery is still fully charged, then i can somehow try to figure out how the rear wiper can be draining power the whole time while the car is off.
really it shouldnt go dead for like 2 months without use!
thanks
