Two weeks ago, I launch at dark, put in the light post and I'm off. Then I realized as I was motoring out, the lights had gone out. It was light enough now to safely not need them. Next time out, same scenerio, same result. ON one minute, OFF the next. So, I start to thinking. I then turn OFF my depth finder. Lights come back on. Finder ON, lights OFF, finder OFF, lights ON.

What gives? Each circuit is run through a different fuse.

Did you check your grounds?

Don't just look at them they may appear to be OK take them apart and clean and tighten them.

I agree with Nitrofreak.  Start at the battery.

Thanks.  Will do.

dave take a wire brush and brush the conectors. i use a dremel and clean off the corrosion. that might work.

not to jack your thread but is it mandatory to have a bow light or can you run a night with just the pole light

I can't speak for electric-only lakes, but on all others the red/green bow light, as well as the white stern light are required.

I had some ground issues with the trailer lights recently that I fixed. I read online that you can put a small nail in the Dremel and wrap a little fine steel wool around it. It's like a steel wool Q-Tip, and it works very well to clean connections.
