Hiya
PCB fuse has 240v either side via me multimeter...

240V potential measused against what?

erm... the earthed casing

Repeat after me

WITH RESPECT TO EARTH AGAIN"

duly repeated ;))

ah the depth of my experience in this domain surfaces ;))

any suggestions how I can more usefully proceed?


You need to test against a neutral on the PCB.

but if everything is measuring 240v wrt earth, it implies there is no
neutral.
