boctal Posted January 12, 2022 Report Posted January 12, 2022 (edited) It appears as though the failure for AC BUS 1 (2) short circuit is not working since it should generate a bus fault. I believe I should be receiving an AC 1(2) AUTOXFER caution EICAS message, a fail light in the associated AUTOXFER light, and the isolated bus outlined in yellow on the synoptic page with no flow. That currently does not happen. Another way this could happen would be with a generator over-current, but I could not find an implemented failure for that (the voltage failure reduces the voltage). When testing this I confirmed all generators and busses were powered. Edited January 12, 2022 by boctal Quote
