My wife uses a Black & Decker Dustbuster and recently it has lost
power and doesn't seem to recharge
I noticed that the plug which connects the base unit to the mains
remains cold. Usually it is warm to touch
I assume that the plug incorporates a transformer. How can I check
this? If this transformer is faulty can I buy a replacement?
Any advice would be appreciated

Forget it, its Dust(bust). :-)

A black&decker stockist will supply you with a new one.
