Troubleshooting a 277 emergency light

[naplespete57]

277 volt emergency light is not working at a plant I am working at. So far I have replaced the battery, didn't help. I do have 277 coming in and when I press the test button the lights come on ever so dimmly for a a second or to. Have inspected for loose wires or burn spots but have found neither. Is there anything else I can do besides replacing the unit?

Thanks as always!

I would swap this battery with one from another pack that you have tested. If you still get dim light check transformer.

Sounds like the charger board has gone out.
I'd go to the supply house and buy another light and be done with it.

Usually it is always more cost effective, to just replace the unit.

I've had similar problems with the same type of fixture. I don't waste time with them anymore. When they fail I either replace the fixture or remove the battery altogether and install an LZ-2 nearby.
