The current is drawn through the CCU and causing problems inside when it draws too much - I was under the impression this faulty design was changed before the 300E was released, but apparently not. Why a 0.02 fuse wasn't included is beyond me.

Yeah, I think I'll add a small fuse just in case. BTW, I unplugged the CCU when measuring the current draw and connected the AWP directly to the battery. The current varied from 1,5 to 2,5A and the pump turned then stopped then worked again and so on.
