ballast replacement question


I am trying to replace a ballast in my upstairs bathroom. The old one has two red, two blue, two yellow, a black and white.

The new one has black, white, one red and two blue. No yellow. How do I connect the new one?

ballast replacement question


I concur with Julius, your description of the original sure sounds like a 4 lamp ballast. What does the new ballast say it's rated for and what does the wiring diagram look like? This info should be on the front of the ballast....but it sounds like you've just got the wrong one.

Either that and with older ballast that is rapid start format that is a common set up and when OP got the new ballast which it allready a electroque ballast the connection will be differnt.

To OP what bulb size are you refering to this and how many as well?

Also post the new ballast number if you can we can able guide ya along the way.

Merci,
Marc
