8 9 VOICE: They are preparing the diesel 1A for the bubble 10 test . . . . (Inaudible).

Il VOICE: They took all the temp switches out last night, 12 cal'd them, and they found one switch, high tube oil temperature, 13 had a little leak around the cover and 0-ring and they also 14 menticned that the switch was appearing to stick.

17 HORTC::: You can't say for a fact that it is. You've 18 ge a number of pneumatic lides with .006 inch orifices that are 19 passing 60 pound pressure through that orifice. And its, its 20 anybcdy's guess as to whether or not this leak is sufficient to 21 have drug dcwn the pressure low enough to have caused the P3 22 trip.

It was just 24 l 25 blewing back in his face.
