Problem with 24" Coralife light

[Glennrf38]

I have one of the corallife lights with 2-moonlights, 2 PC and 1 150W MH. I noticed the other day that my PCs weren't coming on, so I took the covers off thinking it might have been a faulty ....something. I plugged it in and the light came on, so I put it bak on the tank and it ran fine all day. This morning when I went to turn it on, no lights again..... any ideas?

Sounds like you are not making contact with something. ie loose.
Try taking it apart again and rotating the bulb back and forth to "clean" the contacts.
That has worked for me sometimes, in the past.

Thanks
When I checked that, nothing seemed loose or corroded. Is there a "starter" thing like Florescents have?

[hillegom]

I am not an electrician. So do not know about your fixture. I know some flourescents have starters.

OK so now here is a weird update.

Got home after work.
The PCs weren't working.
Took the fixture off the tank.
Plugged it back in and they worked.
Put it back on the tank and they worked.
If it goes the way it has been, they won't work tomorrow morning.
If they don't work in the morning, the only thing I can think of is that there is something loose and when I moved it off the tank, it connected.

But, I gave the fixture a shaking and they still work now.

This is weird.

a friend of mine had a bad ballast and the pc's would turn on sometimes and not other times.
i think jl's just got a bunch of ballasts instock
