Ah, safari let me upload.
Two separate wires at lower right feed the light that works. Assuming there is a buried connection that I have not found. The black vinyl sprinkler piece connected to what appears to be sprinkler line is the feed that failed. In digging I pulled it out. So my next step is to find that wire, verify no breaks, reconnect and hope for the best.
What does the brain trust think of crimped butt connectors inside of heat shrink wrap for this buried condition. I am a good 18" down. Typically in AZ we do not get water penetrating that far. And frankly this dirt is like chipping concrete.
Have my soldering iron (cheap battery powered Weldon) and can a solder.
The extra wire in center left is the offending wire that proved the problem.
