The bulb blew in a 300w halogen up lighter fitted with a dimmer
switch. So I replace it. But it did not work. I swapped bulbs, no
change and I gradually took the lamp apart looking for a break in the
circuit, did not find one.

Without a bulb in the lamp the wires from the dimmer to the lamp have
200+ volts across them. As soon as I put a bulb in the voltage drops
to near nothing without the bulb lighting.

Cant think what the problem is.

Anybody got any ideas ?
