I am trying to wire a new lamp into my cab....can I do this?

OK, so I am looking at the wires in my cab in the marquee area...there are three wires...a grey, a white, and a black wire going to the lamp in there.



on the lamp, there are two wires going to the lamp...one goes to the switch and one goes to the light bulb.





So, what I am wondering is...can I just take the entire thing out of the cab and just hardwire this one in there?

you should be able to... one of the wires heading to the old flouro fixture should be ground... follow the wires to the power supply to figure out which.

Flourescent lamps arent powered by the power supply, they're straight AC.

The three colored wires, white, black, and grey, are the same colors they use on regular grounded AC wall jacks. I don't remember which one is ground (earth ground, not DC ground) though. You should be able to wire the two wire AC flourescent up using those wires, but one with three so it has a ground path is recommended. The picture is a bit rough, but it looks like the grey wire is the earth ground, so you'd want to hook up the other two cabinet wires to the two wires in your flourescent fixture. Finding a place on the fixture to bolt the earth ground wouldnt be a bad idea.

After you wire, before you plug it into the wall to test it, unplug your jamma harness, so there's no chance of a bad wiring harming your pcb.

That's what I was thinking, but I just wasn't sure which wire went to the switch and which wire goes to the bulb...


I guess I can trace it on the cab's setup to see...


thanks for the comfirmation and idea of unhooking the harness

will give it a try

thanks!

My cab has a weird PSU, though -- it eats AC and spits out AC and DC through two different molex connectors (one from each side)

It came in my Dynamo 25".

thinking about trying to fix the old one...going to try and replace the fs-2 starter...

are these things comon? I mean...could I find this at HSC? or another computer parts store? radio shack?

Im pretty sure the marquee light is getting power from the isolation transformer on mine, but I could easily be wrong.

The small little metal (aluminum?) cannister? You can get them at Home Depot type places, maybe even walmart. Just about any place that would sell flourescent lights. Replacing it would be much cheaper and easier than replacing whole flourescent fixture.

and it worked $1.79 for 2 of them and I popped it in and it worked. Time to get a good picture

thanks for the help...and who knows, I may have to do this in the future so it's all good info!
