Where do I find a wiring diagram for my boats navigation lights for free?

Question

1989 17 foot sunbird with a closed bow

Answer 1

I'm not sure if you will be able to get a wiring diagram off line. If one is available it will have to come from the manufacturer.

All fiberglass & wood hull boats have a hot wire & a ground wire going to each light fixture.

This 12 volt wiring is not complicated.

Answer 2

Not sure of diagrams. This is fairly simple. Bow light should have 1-2 screws holding it to the boat. Remove and look at the wires. They probably red and black. Go to the Dash and look under at the Light Switch and you will see the red to the switch. The black may connect to ground block under the dash or go to the battery. One the Stern light it do the same. May actually have two black wires and it really not matter. 12 Volt lights will work either way they connected. But, one wire goes to the switch and one goes to ground. On the switch you will need to determine which is the hot wire from the battery. Test Light can be a big help. Unless there is a horn on the Bow, usually the Bow Lights the only two wires from the front. If, there a Fuel tank there be wires for it and they will go to the fuel gage. I will look around and may find some pictures that will help.
