ATA 27-62, Auto-Speedbrakes was created by Mark

Intermittent EICAS failure warning of the Auto-Speedbrake system.

Found an associated relay K218 (P33 Panel) that had a bad coil. It would act like a car blinker. The coil got hot and went open. It would cool down again and activate the relay.

Great find Mark! I like your power supply unit too. I see many videos on fixing power supply units. FETs, Diodes, and CAPs seem to be the issues.
