How do you test a ballast for fluorescent fixture?
Turn off the power, remove the bulbs, and remove the cover to expose the ballast. If you see tar leaking from the ballast it is bad and must be replaced. If you see no tar then proceed. Use a multimeter to check for continuity. The yellow and blue wires are the power wires and the white wire is neutral. With the meter set to ohms check between the yellow wire and white wire at the end where it connects to the light. If you get no reading the ballast is bad. Now check the other side where power is coming in. No reading and the ballast is bad. If you get a reading at both ends it is good. Check for loose wires.
