Ive got an old boat Ive been fooling with, there's an aerator on it but I dont know if it works, its not hooked up and I dont really know how its supposed to be wired. It has three wires, a green wire, a brown wire, and a black wire. Anybody know how to wire one of these things?

or if anyone knows how i can test it that would be appreciated to? thanks.

If you really want some meaningful help, please provide as much information as you can. e.g. Make, Model, Age of boat,

well i know the black wire is ground, im pretty sure the brown wire is hot, but im not sure about the green wire. If i knew what the purpose of the three wires coming off of the aerator were then it would be no problem for me to wire it up to a switch but anyhow the boat is a 1985 Performance Thruster, its a 15 1/2 ft fiberglass bass boat. Then again I guess maybe black is ground and the other two one pumps water in the other pumps water out, I dont really know.

The third wire was for a timer.  brown and black should make it run all of the time.

Thanks Bud, I believe you've answered my question about that third wire. I believe I know what I gotta do now, appreciate it.

Based on the age of your boat, I agree with Bud.  The third wire goes to a timer.  Does your boat have an "Auto" switch for the aerator?  If so, that's where the green wire will tie in.  The timer on my 1990 was toast, so I bought a variable timer from BPS for about $40.
