Always check the simplest possible cause (such as a loose or disconnected trigger line) of a malfunction first. Then
proceed logically, eliminating other possible causes until the cause is discovered. Where possible, substitute known
good parts for suspected defective parts. Use this troubleshooting information to aid in locating and correcting
trouble.
