Thanks for the replies chaps, i will get a new cap//
So, how do they work then? as said no reg in it just the cap so how does it give a ( clean ) -ish 110 and 240v. It just has a switch, one way 110 the other way gives 240v..
Is there a way to check it out other than changing the Cap i mean, or even after changing it, the winding has four wires three colours and a black.
Lyn.
PS: the grinder is ok as it has been used on the mains 240v.
