Gfic keeps tripping ? The wiring sequence is from the box to the gfic to an oulet to a switch to light fixture #1 to light fixture # 2 using 12/2 with ground. Thanks jimk49

May be necessary to disconnect the last device and try the GFI, to find the section or device that is causing it to trip. Keep disconnecting one at a time until the tripping stops.

If the lights are outdoor, I would suspect moisture or corrosion in one of them to be the problem.
