Kevin - the dimmer is probably knackered. With the rheostat set just a tad off
full brightness a lot of heat is dissipated in a small amount of resistance and
this damages the printed circuit, increasing the resistance and reducing the
brightness.
All the ones I have seen have had two spades on each termninal, so it is a
moments
work (once you can get your hand in) to take one of the wires off its spade and
put it on the spare spade of the other connector.
