Understand electrical power and verify the named test record
Learn how the SkyCourier’s digital generator control units, contactors, batteries and electrical buses work together. Follow the real component names and locations, then interpret supplied maintenance records in an interactive electrical workshop. Start with normal power flow and component locations. Practice generator, battery, external-power, emergency-feed and load-shedding records with the actual test connections and required restoration explained.

Find the actual connection

Locate the main battery, digital generator control units and junction boxes. Distinguish the PN906 battery power connector, PN908 electrical connector, RN902 sense leads, JN901 external-power receptacle and PN901 standby connection.

Use measurements to explain the fault

Work through the 42-page handbook, ten two-part fault cases and three independent five-field jobs. Compare actual switch states, current, voltage and temperature records. Retain the failed observation, verify the repeat and restore the identified connections before closing the job.
