strange light issue

Hi,

Last year the mast mounted lights (masthead, steaming, foredeck) lights all worked perfectly. The boat spent the winter on the hard with the rig up. A few weeks ago she was splashed and life was good.

I checked the nav lights (bow and stern) and they work fine. None of the mast mounted lights are working. Whats strange is that when I turn on any ONE of the lights (mast head, steaming, or foredeck), the LED indicator on the switch panel lights up indicating that ALL 3 switches are on. I have verified with a volt meter that energizing one switch actually powers all of the switches.

What could explain this?

None of the lights are coming on. Could a bad bulb explain this? Do I have a short inside the mast?

Thanks,
Barry

Simple! The common wire is not connected. Probably a corroded connection at the base of the mast. Maybe at the foredeck lamp. Maybe at the switch panel.

Re: strange light issue

Does sound like a ground problem. Probably all the lights use a common ground and it's disconnected or corroded somewhere. When you turn one on the current back feeds through all the others. The weakest link in the system is the connector at the base of the mast so start looking there.
This is why I always wire things like this with separate ground wires. It costs more but when you have trouble with one it's only the one. Easier to trouble shoot and fix.

Conclusion

Hi Guys,

I fixed this on July 4 but forgot to post the conclusion.

You were all right, it was a bad ground. The ground for all of the mast mounted lights was bad on the bus-bar. I haven't taken it apart to see what is really going on, all I did was make up a jumper wire and connect it to a good ground, then I tied the grounds for the mast mounted lights to that and like magic, all the lights work.

I did this on the morning of July 4, which was important because we anchored out with about 100 other boats to watch fireworks. I most definitely needed anchor, steaming, and foredeck lights that night.
