## Discrepancy

ELECTRIC SHOCK FELT IN GALLEY WHEN ELEC PWR IS TRANSFERRED. ENTIRE GALLEY HAS BEEN HAS BEEN ELECTRICALLY DEACTIVATED. NO SHOCK NOTICED WHEN TRANSFERRING POWER.  NEED TO CHECK THE GALLEY ELECTRICAL BONDING AND GROUNDING.  FOUND POOR ELECTRICAL BONDING BETWEEN G1 COUNTERTOP AND AC STRUCTURE (114 KILOHMS).  REMOVED OVENS AND FOUND LOOSE BONDING STRAP.  SECURED STRAP AND CLEANED OVERHEAD GROUNDING CONNECTIONS AND SECURED 106589 OVERHEAD GROUNDS.  REINSTALLED OVENS AND REACTIVATED GALLEYS G1 AND G2.  RESISTANCE BETWEEN GALLEY BONDING POINTS, GALLEY COUNTER TOPS AND AIRCRAFT STRUCTURE ALL CHECKS WITHIN LIMITS.
