7.0 SIMILAR EVENTS
On December 14, 2002 while performing a different PT, a temporarily installed jumper alligator clip failed to establish continuity due to a high resistance connection. The cause of the high resistance was attributed to oxidation on the terminal screw to which the jumper's alligator clip was attached. The jumper's alligator clip was removed from the terminal point screw, the jumper's alligator clip was reconnected to the wire landed on the terminal point, and the PT was performed satisfactorily.
8.0 MANUFACTURER/MODEL NUMBER The failed Train "A" MDAFWP starting relay was a Westinghouse model BFD-24S.
9.0 ADDITIONAL INFORMATION
None.
