I ran the annual SV Backup Battery test today, no problems running for an hour with no power input. I let the battery recharge and shut off the Avionics bus switch to kill power to the SV1000. Normal power lost messages, so I pressed Power Off and the SV1000 shut down. The SV rebooted and came up again on the backup battery power only. Tried the #1 switch to power down and got the same results, the SV1000 rebooted. Had to disconnect the SV battery connector to get it shut down. I think this may be the second time it happened and may explain a depleted SV battery condition alarm I had shortly after installing the V15.3.3 software. Any ideas about what is going on?
