I have a new portable generator that I'm hooking up to some lights on my boat for night fishing. My wires are black for hot, green for ground and white for neutral. The generator came with a male 20 amp plug adaptor that I can use to hook the wires to the generator. Does anybody know which wire goes to which prong?there is an 'N' on one prong, an 'L' on another and the bottom one has three little lines next to it which I think might mean ground.

Switch the ground on the switch to a fused hot wire from the battery and then from the switch to the spot light --ground the light. This will give you the spot light even if the power from the key switch is interrupted.

Most boat nav lights come from the aux or bat side of the key switch.

red and black are power or hot wires white is netrual and green ground need a little more input ,good luck

This should replace any existing single pole (one location) switch. You have two wires on the pir, black and blue and then the ground. The black hooks to the hot or common wire. It may be black, but it will be the hot wire. The blue wire hooks to the wire going to the light. The ground hooks to the green or bare.

White (Neutral) White to White

Blue (Light to Hot) Blue to Black (optional)

Black (Fan to Hot) Black to Black

Green (Ground to Ground) Green to Green

If you do not have a green lead you might see a green screw to attach the ground wire from the house power. The fan has the optional light fixture future connect the blue wire to the black hot wire. If you have the optional light fixture you may want to connect it to a separate switch power.

You're right, green goes to ground.
Black wire connects to Hot wire from breaker box
Red goes to Load (fan, light, motor)

Ok which wire on the switch goes to the Load?
And which goes to Hot from breaker box?

You can test or you can simply hook up the device. If it doesn't work, swap the two wires.
It just won't work until the 2 wires are correct.

Well you need a voltage tester for automobiles or 12 volt systems. The black wire should be hooked to a good ground. Test the wires on the back of the switch for your nav lights. If you have voltage there then you should test each of the light sockets. If you have voltage at switch but not at the light sockets then you need to trace the wires and find a bad spot or replace them. If no power to light switch you need to identify the hot lead (positive) and try to trace it back to the battery. Somewhere there should be a fuse. Need to test the fuse. An ohm meter would be handy to use in troubleshooting this. You not only need to ensure that the positive lead is good but the ground lead also. I"m not sure what kind of boat you have but for instance if it is fiberglass then the boat can't act as a ground. A seperate ground wire has to be run to both lights as well. I'm guessing since both lights don't work that the problem is between the battery and the switch. There almost has to be an inline fuse somewhere. Don't rely on just looking at the fuse. Sometimes they don't look burnt but are. Check the fuses with an ohm meter.

The red and the black are the hot wires. One will be the fan and one is the light. The white is the 'common' for both fan and light.
It sounds like the new fixture has got one hot for both the light and fan, they will both run all the time from one switch. This is the blue wire. Hook it to the red or the black, which ever one comes from the switch you want to control it. Hook the white to the white on the new fixture.
The green is just a ground. hook it to the new fixture green or ground terminal. Cap or the black or the red that you don't use. It won't be need for the new one. The switch that it comes from will not control anything now.

If you have a multimeter which can cost less than $10 or a test light. What you want to do is have the up button pressed and see which 2 wires have power. The 3rd wire should not have power. Then press the down button and see which to wires have power. It should change. Most likely the black is common and feeds power to the switch. When pushed up the blue gets power. When pushed down the green gets power. You may have to provide a ground to the motor from the battery.

is your house older, Some old wires its hard to tell which one is the grounded conductor(nuetral), Both Look black. If this is case You need to test it with a voltage tester- The green and yellow is a ground wire. Test the green with the voltage tester, Along with one of the blacks, if the Black and green set of the voltage tester that black is the hot. hook it up to the black on the lt. hook white to the other black. and green to either green screew or ground wire which ever is provided
