Hi,

snip

... or the mains is wired backwards and the dimmer (electronic) is on the
neutral.

sorry - this would only expain a lit neon screwdriver which you didn't
use... (previous poster)


=================

We mended one at work and had to replace a fast blow fuse.

I've never put a meter on the output of a dimmer, but I guess it might
read 240 volts on the average multimeter if for some reason the slider had
become disengaged from the slider potentiometer - might just not be enough
mark to space to light the lamp visibly.

... I never found an electrical appliance that couldn't be opened BTW - if
you discount the coffee percolator which saw me in casualty when the 3mm
drill snapped and went through my finger :-(
