Hi Kevin,

I am having A very strange problem on my 72′ Sunseeker that I can’t figure out.

I recentlly replaced all the overhead lights throughout the whole boat with L.E.D. lights. All of the lights are powered by 24 volts and are wired in series. I used 12 volt L.E.D.’s throughout the entire boat and they work fine.

I then started on the exterior of the boat, replaced all the lights on the arch, aft deck courtesy lights and the flybridge courtesy lights and they too worked fine. Ok enough of all that.

Here is my problem, The last lights I tried to replace were the port and starbord gunnels, I have nine lights on each side and they are controled by separate switches. I installed all my new lights and they work great for a couple of minutes and then they start flickering and then they stop, and then they start again.

This is driving me crazy!

Can you please give me some insight as to why this is happening ?

Thank You,

Keith

Keith,

Without looking at the system, I would guess that your flickering lights are being caused by a voltage drop problem.

The LEDs turn off when the voltage drops too low. As soon as the current draw goes away (the lights turn off), the voltage rises again and the lights turn back on. This causes in increase in current, a voltage drop in the wire, and the lights turn back off again.

Increasing the size of the boat wiring at least one AWG will probably solve your problem.

It sounds like you have a wonderful boat. Can you send me pictures of your project that I can post on the site?

Thanks,

Kevin
