During a second surveillance test conducted the same day, the lA Diesel Generator again failed to start due to the same cause. The rack handle linkage to the fuel racks of the 12 cylinder diesel was disassembled, cleaned, and relubricated. In addition, heat from a heat lamp was applied to the diesel governor assembly. The 1A Diesel Generator was then started and tested satisfactorily within the time limits allowed by the Technical Specifications.
It is  not known whether malfunction of the linkage or abnormally cold weather effects on the oil system caused the problem. In lieu of the previously reported proposed corrective action, the following has been accomplished.
The cleaning and removal of paint from the rack handle linkage is considered to adequately remove malfunction of the linkage as a potential problem.
Prolonged periods of below-freezing weather are rare at the St. Lucie site.
However, to enhance governox operation under such weather conditions, the governor oil has been changed to a lower viscosity type as allowed by the manufacturer's technical manual.
This  is the third occurrence of a diesel generator failing to start properly.
The previously reported start failures involved a clogged air start system solenoid valve and air line (335-76-21) and an improper air start valve lineup (335-76-44), and are unrelated to this occurrence.
