Narrative:
During taxi-in the #1 engine was shut down to conserve fuel. Upon doing so, all electrical power, including battery power, was lost. This left the aircraft without any radios or gyros, including the standby horizon. All attempts to reset circuit breakers, restart engines, obtain emergency power, etc, etc, were futile. The APU was on MEL. With no radio communication possible, the air carrier was escorted from between 2 active runways with the assistance of the newark port authority. The aircraft was turned over to maintenance and subsequent flts cancelled.

Title: LOSS OF RADIO CONTACT AND EVERYTHING ELSE IN MLG'S LOSS OF PRIMARY ELECTRICAL PWR SUPPLY IN TAXI-IN AT EWR. FUEL SAVING PROC IN USE OF 1 ENG SHUTDOWN TAXI PROC.
Narrative: DURING TAXI-IN THE #1 ENG WAS SHUT DOWN TO CONSERVE FUEL. UPON DOING SO, ALL ELECTRICAL PWR, INCLUDING BATTERY PWR, WAS LOST. THIS LEFT THE ACFT WITHOUT ANY RADIOS OR GYROS, INCLUDING THE STANDBY HORIZON. ALL ATTEMPTS TO RESET CIRCUIT BREAKERS, RESTART ENGS, OBTAIN EMER PWR, ETC, ETC, WERE FUTILE. THE APU WAS ON MEL. WITH NO RADIO COM POSSIBLE, THE ACR WAS ESCORTED FROM BTWN 2 ACTIVE RWYS WITH THE ASSISTANCE OF THE NEWARK PORT AUTHORITY. THE ACFT WAS TURNED OVER TO MAINT AND SUBSEQUENT FLTS CANCELLED.
