## Discrepancy

CAPTS VSI STARTED SPARKING WHEN AT THE GATE IN SLC BRIEF ELECTRICAL FIRE FOLLOWED BY SMOKE IN COCKPIT.  C PERFORMED EXTERNAL LEAK CHECK OF AREA ABOVE CAPT'S INSTRMENT CLUSTER NO FLUID LEAKS DETECTED. FOUND AN EMPTY SCREW HOLE IN THE GLARE SHIELD ABOVE THE INSTREMENT CLUSTER THAT HAD A BROWN FLUID IN IT.  INITIALLY THE FLUID ON THE EXTERIOR CASE OF THE IVSI WAS WET.
