4th post dude.

The charger will only draw what it needs to, if it shorts internally it will blow a 5, 10, 15 30, amp fuse etc, regardless of whats protecting it.


I wouldnt loose sleep over it though 

Using that logic an extension lead wouldn't be fused? I only put a 5amp in cos the most I'd draw would be 3-4 amps. Personal preference I'm sure.

Why do you say that?

[simonm]

Most cig lighter accessories are already internally fused (a glass cylinder fuse) , including usb chargers. All the cig lighter really is an extension lead to the battery that is fused.

I've never looked inside a tyre inflater though tbh, I don't think one would fit under a bike seat anyway would it?

[alexanderfitu]

Oh right, I see what you mean.


If the extension lead to the battery wore against the frame at one point and through the insulation, it would be a dead short and would then blow the fuse. Thats the reason you keep the fuse as close to the positive terminal of the battery (or wherever it goes) as possible.


Lol no mine doesnt, I keep it in my "emergency pack" which is in my top box. Tyre inflator, puncture repair kit, breakdown info etc. Its helped me at least once!

[simonm]

Alex, I'm sure you're right, I don't want to argue.

You put your fuse in, I'll put mine in. No harm done Tis only a lighter socket  :lol

In your use scenario a 5amp would blow as much as a 30amp would blow  :eek

[alexanderfitu]

:o  I wasnt aware we were arguing! Apologies.

I like your riding btw. Smooth and considered. Much more commuting style rather than angry/aggressive

The fuse in the cable to something, isn't there to protect the "something". It's there to protect the wiring, and hence your motorcycle, from over heating and catching fire.

Not quite sure where that fits in the argument, but always worth the reminder :-)

It's to protect both surely. If it was just there to protect the bike why would there be different value fuses? The reason is to tailor the protection for both the circuitry of the bike and the accessory connected to it. Having a 30 amp fuse with a 5amp piece of wire would do no good. You tailor the fuse to the duty that it's performing. Admittedly a tyre inflator is a good example of where 5 amp would be wrong but using a 30amp fuse on your home lighting circuit wouldn't be a great idea either.

Maybe I'm wrong. I dunno. I give up.

Thank you 90% of my riding is commuting stuff, so its through lots of traffic. Lots of central london stuff as well. I always ride conservatively. Better to be safe than sorry.

This thread is quite old I found it when I was looking for information.
Today I installed a 12 V socket for my nav.
I do not like the direct connection to the battery for the nav I prefer switched 12 V (there is a Ctek-socket directly connected under the seat for charging),  and I hate drilling holes in the fairing. So I chose as location left of the ignition switch (have it similar on my TDM).
First step was making a mounting bracket for the small 12 V socket (I do not like the cigarette lighter type).
After testing with some cardboard templates the bracket was made of 2 mm aluminium. The Bracket is fixed on the left riser



Socket installed.



The Fazer has like the TDM switched 12 V on the horn (the horn switch closes to ground if activated). So I connected the socket to the horn.

[Brettholmes89]

I want to do this on my Fazer. Is that just a 12v usb socket wired into your horn? Or is there more to it than it seems?

[riedrider]

It is not an USB socket. In Germany it is called "small DIN socket".
I used this one but made  my own bracket:

Sounds like a bad idea to me.  Far too likely to get tangled up in the steering.

What? I have a customer with that many accessories on his bike I have had to fit a secondary fusebox. He has plug sockets on both infill panels for different things and the have never once interfered with the steering in any way.  :wall

mines on the right inner fairing
works a treat wired to headlight with in line fuse  :lol
