Question on Cig Lighter and Fuse

[jammer]

I blew a fuse. In looking..I noticed that it was to the Clock and Cig LIghter. I replaced the fuse and it all started working again.

Question: I noticed that when I used the Cig Lighter after replacing the fuse..the fuse, 10amp was hot. Not warm but hot. Is that normal? When I bought the boat it did not have a clock on it. Now it has a Teleflex Clock on it. I wouldn't think that would pull many amps.

Opinions please.

Thanks in advance for your help.

What are you running from the cig lighter outlet? The clock takes a very small amount of current so something else is on that circuit.

I just went over the entire circuit. It's only the Cig Lighter on that...I added the clock aftermarket. Those two things are the only thing on the 10amp fuse. Now if I am wrong this wouldn't be the first time; however, Both live wells, lights, internal lights..nav lights, bildge pumps etc. They all worked. Plus on the fuse panel..it only shows the Cig lighter.

Opinions?

Re: Question on Cig Lighter and Fuse

You have a short on this circuit somewhere. The fuse should not be hot. For a sanity check, pop the fuse and make sure everything else is sill working. When you;re touble shooting it, try and visulize a divide and conqure theory. What can you elminate by disconnecting.

Right right..keep talking. Right up my alley. With the cig lighter not on..just the clock...the fuse is cold. Push in the cig lighter..after it pops out...the fuse is hot. That is the last check I did.

Here's my idea. A cig lighter assembly is cheap. Just put in or buy a new one and see. I think the kids over the weekend by holding in the lighter like a car blew the fuse.

Opinions.

And thank you all.

Re: Question on Cig Lighter and Fuse

Ten amps is pretty small to fuse a cig lighter. They draw a lot of current.

After you confirm that nothing else but the clock and the lighter are on that fuse, change it to 15 amp.

Re: Question on Cig Lighter and Fuse

So it is actually a cigarette lighter you are using and therefore thats the reaon things get hot. A lighter is heating element and they draw lots of current. Changing to a 15A fuse is ok so long as you have at least 14 gauge wire in the complete run from the fuse panel to the lighter and that includes the ground wire.
