Troubleshoot 1 uplight for front tree not working. Tested voltage at fixture and got 2.0 volts only. Dug up wire lead and found a loose wire connection several feet away, likely caused by tree roots which were growing over the wire connections there. Wire could also have been pulled. Repaired wire connections and retested good. Existing bulb is not worn out. Tested output current at transformer: 7.0 Amps (~98 Watts). Customers not available—Approved over phone.
