Tested lights from 3 transformers. Noticed that one timer was not plugged into the transformer which was causing those lights in the back not to work. Found not working: 1 well light, 1 wall mounted light, 1 small uplight with integrated bulb (right side), 1 ornamental light behind pond, and 3 uplights in the far back right. Quoted customer to replace bulbs, replace fixtures, and add 1 uplight and wire, however customer declined at this time. Did some electrical testing also, and determined that 2 exposed wires do not appear to be getting voltage. More troubleshooting and wire would be needed.
