I was repairing some landscaping lighting, and when I took the cover off

there, maybe 1/4 to 1/2 cup. I'm guessing it wasn't enough to reach the
wiring connections, held together by wire nuts, or maybe it did.

Because if it had, the breaker would have tripped, right?

Hi,
If it is not GFCI, and pure water is not a good conductor. You should
have drain holes on the box and liberal use of silicon sealant to
minimize water/moisture build up.
