The lighting system is a project that I had been working on all summer. Today after working through snow and ice, I finally got the lighting in the pond to work. The big test will be seeing if it still works after we fill the pond. That can wait until next summer.
The original installation of the lighting was quite odd. There was an assortment of timers, no two being alike, several timers in the garage (only one for outdoor lighting), two hidden under a furnishing, another hidden behind the fountain, and none labelled with what they were for, and none of the lights worked when we moved in 2 years ago.
I spent $300 in bulbs, and replaced the halogens with LED's. Which didn't work. I ended up hand excavating the lines to try to find a break in the line since the entire north side of the yard didn't work, or seemed not to.
