Troubleshooting Questions

I have a customer for whom I installed four Kichler 15732 LED uplights
in his yard August 2010.

He is happy with the lights except that (coincidentally I think), his
GFI trips intermittently.

I checked the system for shorts and couldn't find any. It's a 10 year
old Unique transformer with a fuse, and the fuse does not blow. It's
just the GFI tripping.

I concluded that the had to be either the GFI itself, the line voltage
side of the transformer, or maybe some other device on the same
circuit with a big power demand turning on at the same times as the
lights.

I think what I am going to do is take a spare transformer over and
temporarily replace his (I have a Vista MT on hand I think.)

What would you do? What about the notion of something else on the
circuit that turns on at night? He doesn't seem to know what else is on it.
