I was hoping someone could provide some advice.
My downstairs hall light will not switch on. It is a halogen (10x 10w) light from Ikea. It has a 105VA transformer stepping down from 240 to 12V AC.
The input to the transformer (measured with digi multimeter) is 240v when light switch is on but output from transformer is only reding 1.5v - I presume this means the transformer is faulty?
Also, when the light switch is off I am reading about 40v between the switched live and neutral feeding the transformer. Is this normal or does it indicate a fault and possible reason for the transformer failing after 6 months of use?
The 3 way switch in the hall also feeds an outside light. This also blows bulbs regularly (once a month) and there is a residual voltage of about 40v when switched off?
Are these induced voltages or is there something more serious and if so how can I fault find. I am relatively good with electrics but this is a new one on me.
Please help.
