Singer Featherweight: Nothing happens due to blown fuse or power cord break

To determine if the power delivery system is compromised, perform a continuity test on the power cord and inspect the machine's internal fuse. Use a multimeter set to the continuity/ohms setting to check for a closed circuit across the power cord pins. If the multimeter shows infinite resistance or 'OL', the internal wiring of the cord is broken. Additionally, inspect the fuse holder located near the power intake; a darkened or broken wire element within the fuse indicates a catastrophic electrical failure preventing power from reaching the motor.
