OK, I guarantee this is a first for this site.
I'm debugging -- of all things -- my landscape lighting. Here's what's going on:
1) The bulb stopped lighting in the socket one day
2) I measured the output at the transformer (ac 12v) -- right at 12v measured with DMM going into the wires feeding the light
3) I measured the output at the socket -- right around 11.1v
4) I measured continuity on the bulb -- it has continuity so it isn't blown
5) I took a few scraps of wire and hooked it up directly at the transformer and ran it to the bulb and it lit
6) I can stick these scraps of wire into the sockets of the fixture and get 11.1v and touch them to the bulb and it will NOT light
What the heck is going on? Is 11.1v not enough to light a 12v bulb? Surely it should light but be dim? Or is there something else going on?
It looks like I'm losing a bit of current as I've dropped from 12 at the transformer to 11 at the light fixture...
Thoughts?
