Had a 4 car bank with a swing car doing that crazy shit one time... westinghouse mark iv... they would shut down, gensets would stop, then all of a sudden start running on their own... seems they were emergency dispatching...

turned out to be the phenolic ladders on the FH relays on each controller...

happened on thanksgiving day at a 14 story highrise that was serving 2000 dinners that day on the 14th floor... GM signed papers for the MOD that afternoon... true story...
