We just got our Valor 29t18 and we cannot figure out how to turn off the lights under the carriage off...appreciate an assist.

Same issue also. Anyone solved this? I'll start following wiring from outside in & see what's going on this weekend. Pulled control panel and reversed the wires into the back of the switch and no change - still could not turn off ground lighting
