Hi all,

My bathroom light halogen bulb (1 of 3 on a centre light mounting -
bathroom-safe) came to the end of its life and popped, throwing the main
lighting tripswitch/fuse.

When I reset the fuse and put a new bulb in, I notice that ever since then
the entire lighting rig in that room only, flickers now and then. It's on a
pull-cord, and the flickering is like what happens when you pull the cord
down slightly but not all the way.

Any ideas where to look for the fault?

Mm. Probably a switch or contact has arced a bit under the high load and
become unreliable.


In my electronics days, this usually involved srpaying the boards with
freeze spray until we found the general area, then a bit of wiggling or
close inspection found the bad connection.

Try careful wiggling of switches and junction boxes.
