    56MY anchor / Nav lights are crisscrossed

    I want to replace Nav lights which were not working. The only thing changes was the actual fixtures.Now the stern light and starboard light come one when switch is part way out. The port light comes in with switch all the way out.Does anyone know where wires come together.The back of the switch at both helms has wires 309, 310, and 311 connected. That all looks stock and original.Thank

    3 position pull switches, Toggle or rocker nav light switches all work with with the same theory.
    B+ to one lead, one position applies power to one set of lights, the next position applies power to the next set of lights. All lights return to B- or ground. Pending a common anchor light/steaming light, a diode may be involved.

    If all lights are using standard incandescent lamps, I would say something is mis-wired on the switch.
    If your new lights were LEDs, an whole new headache appears.
    So my first questions;
    New LED lights?
    Combination steaming / anchor light?
    Single station light switch?

    Good information. There are 2 stations. Push/Pull style.Once it became dark it was much easier to troubleshoot. Both switches appear to be very intermittent. The lights flash and flicker when I wiggle the switch. Most of time, the wrong combinations came on, but I was able to get the correct ones on.The lights by the way, are new Hella multi volt series and work natively with 32v.On fly bridge, I have one forward facing white light, and one anchor light.At this point, I will replace both switches and see if that sorts out.

    You have the wire that powers the port running light connected to the anchor light circuit. The first position is all of the running lights and all the way out is the anchor light.

    Well, new switches did not solve problem. The problem is not at switches, as there is only one wire going out to Nav lights. They must junction elsewhere. Do anyone know where those terminal strips might be?On plus slide, flicker and intermittent is solved.

    There are two terminal strips where these wires lead from each helm switch. One is under each helm. Follow those wires down to the terminal strip. You may need to clip a few cable ties to separate the wires in each bundle to be able to trace them.
