I put a gfci outlet in my front yard for use during christmas time for lights and such. i ran it to on my front porch light so it only turns on when my front porch light is on. i also added to the gfci a light about 20 feet away so that it lights up a dark area. I turned my breaker on and the gfci works but the light doesn't turn on. why is this happening? Ive tested and reset the gfci. unfortunately it got too dark to work on the wires. what could be the problem as to why there is no light going to the light post?
It turns out that the OP's problem was caused by a loose connection that slipped out when he attempted to fit the light fixture to its pole, as per his comment:
Thank you guys for the help it turned out the black wires weren't touching they somehow slipped out when i pushed the light on the pole
Check the ground on the new light. It could be tied in in a way that trips the gfi. Also if the wire is getting wet to the new location.
