12v halogen recess light has power but doesn't turn on
Hello Guys,
I am looking for some advice on fixing a low-voltage shower recess light fixture (Nora Lighting NL401), which uses a MR16 GU5.3 halogen bulb. I replaced the bulb but it still would not turn on. I initially thought it is an electrical problem, but when I took a multimeter and measured the voltage at the bi-pin base for the bulb, it shows 11.8v. I tried several bulbs so to make sure that it is not a random burned bulb. Do you guys have any advice on what other problem that might be? I did not think these 12v halogen bulbs requires any ballast. Could it be that even there is a voltage, a malfunctioning transformer is not providing enough current to the bulb?
Thanks for any advice.

It could be a defective socket too. From the extreme heat of those bulbs the pins lose their tension and don't squeeze the pins tightly. The sockets are usually replaceable.

When I had halogen puck lights several of the sockets failed. Sometimes inserting and removing the bulb several times would wipe the contacts and get the light to work for a while but it usually indicated that the end was near for that socket. The best source of spare parts I found was another light kit and I'd just scavenge it for parts.
