LER #315 In this short video I complete the repair to the Emergency Backup Power controller PCB – I’ll show you how I managed to suubstitute the SPST replay with a SPDT of the same voltage rating, because i could not get one of the original type, and how I replaced the bridge rectifier where the PCB was badly damaged.
