I have a low voltage ceiling pendant light on a dimmer switch that started dimming and stopped working. I checked the bulb and power to the switch and both were OK. When I connected the switch wires the light worked fine at full power. So I figured the switch was bad and bought a new, identical dimmer switch. But it didn't work either. So I hooked the light up to a regular switch and it works fine, albeit at full power. Hard to believe both dimmer switches could be bad?
