Checked for incoming power?
Good point, joe, but yeah, it is in a SERIES - theres a working unit before AND after it. Thats what is getting me. Other culprit could be the main feed wire could be grounding on the metal case/box.....but doubt it.Checked for incoming power?
OK, Joe, then what should I do? Check for voltage at the blk/wh low v wires? Or the red/blue wires? What should one get for V reading? What V should one see there? I already did ohms......Still could be a power problem. The wires on the ballast are smaller than the line wires and sometimes they don't connect even if the power wires do.
guess it could happen, (mentioned in my 1st post I replaced with new). Have you ever seen a "new" ballast be bad?Bad ballast.
Tug on the power wire connections and see if they pull out. Undo the power wire connections and redo them.OK, Joe, then what should I do? Check for voltage at the blk/wh low v wires? Or the red/blue wires? What should one get for V reading? What V should one see there? I already did ohms......
Is this a slimline ( single end pins useally either 60 or 75 watters ) or High Output ( recssed double pin useally 95 or 110 watts ) ??have a 2 bulb, 8' fluo fixture, replaced ballast, but on 2 new bulbs (tubes), and no light. So, took Ohms readings of both terminals (one blue/red wires, other blk/white), and one terminal 160+- ohms, other 80 or so. Are these good readings? What is ideal? Am I on the right track?
Thanks
Whats the diffreence between the input wires and output? Is the input the white/blk? And output is red/blue?Since you know the ballast is good, you don't need to measure the output voltage. Just reconnect it in the right fixture, exactly the same way it was connected in your test fixture. Make sure the input power connections and the lamp socket connections are solid. If it still doesn't work, check voltage at the input (probes under the wire nuts). If it still doesn't work, then use a non-contact tester to check for power on the output wires - if they are hot and the fixture still doesn't work then it's probably a bad lamp socket.
