156. Lamp Socket Failure

SUBJECT: Lamp Socket Failure
REVISION: 04
MODELS: Venders Utilizing Hi-Output and Slim Line Lamping w/Serial #’s 1343-0001 CH to 1449-5000 DJ

PURPOSE:
Recent customer feedback on a very small group of venders in outside locations have exhibited a localized harness melt down within the vender door and in the proximity of the lower lamp sockets. Investigation has indicated that moisture has gotten into the socket and over a period of time has created a high resistance path to ground which in turn may cause the socket to over heat and produce the melt down.
