How do I wire the fan wires to the cabin dome light

[TheOtherLine]

I bought one of those oscillating fans for the cabin and I am going to attach it to the starboard that holds the cabin dome light. But, I want to make sure that in doing so, I don't have to have the light on for the fan to work. Is it just as simple as connecting the red and black wires on the fan to the same leads on the dome light or am I missing something?

Oh. And for Dale's benefit, the magic word. Dielectric. Done.

Should work since you would grab the red before the light switch.

I have a two-speed Hella Turbo, draws 1/2 amp. I wired separate but no big deal.

Here is a photo of mine mounted at the front of the cabin.

The wiring should be hot anytime the battery switch is on.
As Dana mentioned, the light is controlled by the switch, so you should be good to tap into it for your fan.

Here is what my wiring looked like when I replaced my (too dim) cabin light.

Old LED light

New LED light

It is easier just to get the battery powered dome lights from Home depot :lol:

Okay. I am not sure what to do here. The black wire on the light which connects to the switch, is crimped to a another wire above which is blue/red. The othe black wire that is wire connected to the other 2 black wires, is crimped to another black wire.

To which wires do i connect the red/black, and solid black wires on my fan, to which wires on the light?

Incandescent lights don't care about positive or negative, so it wouldn't matter how you wired the light
(LED's on the other hand, are polarity sensitive)

My suggestion would be to wire it temporarilly and give it a try.
If the fan runs backwards, switch the wires.

Didn't even think about the fan running backwards. :shock: I just wanted to make sure that the light doesn't have to be on for the fan to run when I hit the switch on the fan.

So what you are saying is I can tap one of my fan wires into any one of the red light wires and the other fan wire to any of the black light wires and I should be ok? (other than the fan spinning bacwards).

Correct!
Hook the fan wires to each of the wires feeding power to the light, and you should be good.
The light will work normally and the fan will 'share' the electrical feed.

The black wire on the light which connects to the switch, is crimped to a another wire above which is blue/red. The othe black wire that is wire connected to the other 2 black wires, is crimped to another black wire.

From this description it seems the blue/red wire is positive constant power and the black coming out of the ceiling is negative.

So what you are saying is I can tap one of my fan wires into any one of the red light wires and the other fan wire to any of the black light wires and I should be ok?

If you do it this way the light will need to be on for the fan to work.

Wire the fan to blue/red as positive and the black as negative.

Thanks for the advice guys! :shock:

Hooked up the fan the way BryanA suggested and it works perfectly.

Thanks

I love it when a plan comes together... :wink:

BTW... nice 'fro. :lol:

I would't listen to me if I were you. :shock:

Just kidding, glad I could help.

Thank You. Took me 9 months to re build. Luckily for me there were only wires to hookup :lol: Electrical is not my forte.
