On approach, the crew lowered the landing gear, but noticed none of the gear position lights were illuminated. Prior to landing, the captain found both the public address and interphone to be inoperative. A visual approach was performed with a normal touchdown. During rollout, the crew discovered that the thrust reversers would not deploy. After turning off the runway, the flight attendants began to smell smoke. The captain stopped on the taxiway and initiated an emergency evacuation. One passenger received a minor sprain while using the emergency slide. An inspection revealed that a multiple system loss had occurred due to the 28-volt DC battery bus going off-line. The condition was duplicated during troubleshooting and the failed part was identified as a battery transfer relay (R2). The source of the on board smoke was not identified.
Probable Cause: The failure of the battery transfer relay resulting in multiple system failures.
