Received the replacement circuit board from E-bay 2 days ago
Spent time Wednesday opening the old battery pack removing the old circuit board and soldering in new one
Had to remove (cut out )thermal sensor off the support frame of the battery pack it was interfering with the new CB sitting flush ( new component sits on the bottom of the board.
Works ! will hold charge over night unplugged and didn't burn down the house.
I do have the new (replacement) battery in the vac. and after charging it before using it and then left off the charger overnight it lt drained over night.
Reading the from the Dyson web site it states that the battery is designed to stay on the charger at all times when not in use.
