Re: Can a dimmer switch be bad, but still work?
Electrical continuity is simply a continuous path (conductor) for electricity to flow, which can be checked using a multimeter on the ohms setting. A multistrand copper wire can check out completely fine using a continuity test, if even all but just 1 strand are broken. However, when that wire is asked to support a load, it most likely will fail due to high resistance along that single strand.
Dimmers are notorious for going bad, especially most aftermarket garbage. Check for 12v at the plug on the dimmer.
