Shed yet to receive power for tool's lead (5)
I believe the answer is:
spill
'shed' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for spill that I've seen before include "Upset - lighter" , "Firelighter" , "Waste (liquid)" , "Overturn" , "Taper; slop" .)
