Hi All, I was hoping someone might be kind enough to offer some advice please.
We moved to a new house and got rid of an old bathroom cabinet with a light above it. I’ve just got around to fitting a new cabinet and separate wall light. I’m not sure if the old light worked as it didn’t have any bulbs in it.
Having wired in the new light the led bulbs that I put in were very dim. I thought I’d just bought some poor quality ones so ordered replacements. They arrived but still dull! I tested the fitting with a volt meter and got a reading of only 97 volts. I took the fitting down and checked the connections. Both looked fine. Checked the switch no loose connections there either.
I Swapped the l1 from the mirror switch with a neighbouring switch one. The voltage across the one that I moved the mirror cable to dropped to 97 volts and the one the mirror light had used went up to 240 volts so I don’t think it’s the switch. They have linked common wires.
There is a permanent live to the fitting so I swapped the existing l1 wire for that. This made the lights work perfectly and brought the voltage up to 240.
I then decided to remove the l1 from the switch and replace it with the permanent live feeding the mirror light with a view to making it work on the switch. Having done that, the voltage dropped back to 97 and the mirror lights went dim again. It doesn’t take much but I’m baffled! Would anyone be kind enough to suggest anything else I might try please? Many thanks.
