Author Topic:   Navigation Light Wiring: Perko White All-Around Lamp

I just purchased a [white all-around lamp] from my local Whaler dealer. It is a Perko light. It came with two wires coming out of the base going into a polarized plug. The thing is, the grey and the black wires going into the plug and coming out of the plug are reversed. How do I know which to connect to the postitive (usually grey) and which to connect to the negative (usually black)?

(Jim, how do I post a picture of this?)

For help with authoring articles, please read the article linked under "author help" which appears on every page of the discussion area.

The black conductor is used for wiring the battery negative leads.

The gray conductor is used for wiring the battery positive to navigation lighting loads.

Please explain in more detail where you think the wiring has been done with the polarity reversed. In a connector the same wiring color code should be used on each mating plug, that is, if a plug has a pin-1 and it is wired with a black wire, then the mating jack should have a black wire connected to the mating socket for pin-1.

Exactly. I will try to post a picture of the wiring to illustrate it. There are 2 wires coming out of the light post. One is black and one is gray. It came from the manufactuer with an in-line plug already attached. The plug has one prong and one socket on each side. The side leaving the plug has two bare wires to butt splice to the navigation light lead and the negative terminal. The wierd thing is, the wires coming out of the plug are reversed, i.e. the black wire plugs into the gray lead and the gray wire plugs into the black lead. If it were reversed (normal) I wouldn't have any question, I would butt splice the gray to my positive (nav. light switch) and the black to my negative. If I figure out how to attach a picture, you will clearly see what I mean. I will give it a go. Thanks.

Just swap the conductors on one of the connectors so that they match the other side. If you want to be particular, the black conductor ought to be wired in the lamp fixture to the base of the bulb socket. In the lamp both conductors ought to be isolated from the mounting pole.

I think this link will work. There should be 2 viewable photos on this site.

One side of your connector harness is made up incorrectly. You can either trace the leads to the socket for the lamp to be sure the black is connected to the shell (as opposed to the pin in the center of the base) or you can just connect the black from the pigtail to your negative bus and the gray to the load side of your switch. If you connect it "backwards", it really does not matter to the lamp.
