## Discrepancy

THREADED STUD ON THIS TERMINAL ADAPTER LUG HAS IMPROPER THREAD PITCH/DIAMETER FOR PROPER INSTALLATION OF WIRE TERMINAL NUT.  IF THE NUT IS THREADED ON THE TERMINAL AS DELIVERED FROM RAYTHEON, THE THREADS ON THE TERMINAL STRIP OUT.  IF THE ADAPTER IS USED AS DELIVERED, PROPER TORQUE ON THE TERMINAL NUTS CANNOT BE ASSURED AND RESULTANT LOOSE WIRES AND ARCING CAN OCCUR.  THIS CONDITION HAS BEEN NOTED ON THE VAST MAJORTIY OF PREVIOUSLY DELIVERED ADAPTERS AND DIRECT CONTACT WITH RAYTHEON HAS PROVIDED NO IMPROVEMENT IN THE DELIVERED PRODUCT.  THIS ADAPTER LUG IS PART OF RAYTHEON 1900C STARTER IMPROVEMENT KIT NR 114-9034-1.
