I am new to this group but may be using it a lot since I have just bought a
house that is turning out to be a true Handy Man Special.

Question: Some of my receptacles will run low voltage such as lights, but
not very bright. A hundred watt bulb will only look like it is 50W. A
vacuum cleaner will not even work.

I have replaced all receptacles in the bedroom but there may be more
switches and receptacles on this circuit.

Can anyone tell what the problem may be and is there an easy way to test it?
