Hi,

I have been called back to a job where a 3-halogen lamp fitting with 2 way switching keeps blowing a bulb. When this happens and the switch is turned off the remaining 2 lamps stay on but very dim. When the blown lamp is replaced, all is well again. I have tried everything. Isolated it from upstream lights, changed both double switches and tightened all terminals. Any ideas? Thanks.

sounds like a job i did not long ago!!

customer had new loft insulation fitted!!
installer disturbed a junction box and the live feed for intruder alarm came out!
been the nice installer he was he reinserted the red cable in to the red connector! (how ever he connected to the wrong red bit and actually connected to switch line from the landing light!

outcome!! when light on stairs is on it powers light and charges intruder alarm!
when light off it also disconnects alarm and the battery in alarm powers the light very dimly!

is your smoke doing the same!!! possibly the battery feeding the light!! i would double check the connections!!


may i also add the loft guy also mashed the screw terminals in JB!!! PRAT!!!!

I fixed the problem in the end. I just fed the smoke into a jb on the same circuit just upstream and hey presto. Very strange, it deffo wasn't the switch wire I was feeding into! One of those mysteries.
Cheers All.

My guess is an earth to N fault in the damaged light fitting. This will become a problem when other devices draw large currents.
