A » To test a fluorescent ballast, first ensure the power is off and safely remove the ballast. Using a multimeter set to resistance, check the continuity of the ballast. Measure across the input and output wires; a reading within the manufacturer's specified range indicates functionality. Inspect for physical damage or burn marks. If unsure, consult a professional electrician to prevent hazards.

A »To test a fluorescent ballast, first ensure power is off. Remove the fixture cover and disconnect the ballast. Using a multimeter, check for continuity between the input side wires; it should read infinite resistance. Test the output side wires; continuity here indicates a functioning ballast. If any readings are off, the ballast may need replacement. Always prioritize safety by wearing insulated gloves and following electrical guidelines.
