How do you replace ac ballast where emergency ballast present?

First you need to determine if it's the ballast that's bad or the emergency ballast. The emergency ballast can go bad and cause the bulbs not to work or not all of them to work depending on the lights wiring setup. Push the test button on the emergency ballast which should have a red glowing indicator light. If all the lights illuminate slightly, change the emergency ballast. It's best to buy the exact ballast for this repair. i.e. If it's a T8 3 lamp fixture. Buy a T8 3 lamp ballast not a 4. You can use a 4 in place of a 3 lamp, but the 3 lamp will be more user friendly. Easiest way is to note what wires go to what. Draw a diagram if you have to and just simply match them back up.

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.

Ballast gets hot when trying to start 77 power wagon?

AnswerThe ballast may need replacement as this acts as a fuse in the system. You can momentarily jump the ballast to see if it will start. A ballast that keeps going out is sometimes caused by bad spark plug wires. Or secondary voltage jumping from coil tower to primary [ballast side] terminal.
