Hi Guys.
I have a new Ventura 180 that has a short of some kind in the circuit for the running lights. To wit: occasionally the red-green light will not come on and the all-around light works fine. The boat is still under warranty but I would like to try and fix it before I take it back to the dealer. Any ideas? Thanks.

Have you tried twisting the bulb in the recptacle?

Or give the fuse a twist. It worked on my Outrage 18.

You don't have a short, you have an open.

First thing I'd do turn them off, and back on again. If that
fixes it, I'd be thinking switch problem. Also check the
connections on the back of the switch.

Are they separate red/green lights on the sides or a single
bow light?

At least on my Montauk, all the lights are on the same fuse,
and I'd suspect yours is too -- so the problem is not the fuse.

What would you suspect if there is a slight delay when you turn on your stern or bow light? Perhaps about a 1 to 2 second delay, and then the light goes on...

I'd suspect a bad connection somewhere, probably something
to do with salt water corrosion. Could be anywhere there's
a connection including inside the switch. If the switch has
a pilot light, watch it. If it does the same thing, the
problem as at or before the switch:

Step 1, pull all the wires off the switch and fuse, and put
them back, one at a time, then start watching for the problem
to reoccur.

Step 2, replace switch.

If the pilot light doesn't do it, watch the lights to see
if the all do it at the same time. That may give you a handle.

My problem child was the plug where the anchor light plugged in.
I finally gave up and used a straight run of wire. It's been
absolutely trouble free for several years now.

My trailer is doing something similar because the plating on
on the flat four plug has gone away, and some copper compound
is getting in the way of the electrons. If the lights don't
come on after a second or two, I just touch the brakes and
that seems to blow a hole in the barrier.

It is typical in a small boat like a Boston Whaler that the navigation lighting is controlled by a three position switch. The wiring to the all-around light is separate from the wiring to the sidelights. The problem you describe could be either in the wiring to the sidelights or a a bad pole on the switch. To remedy this I suggest checking the wiring between the sidelights and the switch, and checking the switch itself. Often a little WD-40 sprayed into the switch contacts can relieve a problem like this.

Thanks guys. I have thought of some of these tests and will try the others. However, my first mate, (actually she's my second), reminded me that the guy that did my canvas drilled near where the wiring runs forward to the running lights. DOAH! This may be the problem.
