Hi all.

I am just about to install a 12v socket inside the fairing so that I can keep my gps charger always plugged in and so I don't have to have a cord running down to the 12v socket in the 'OEM' position by the right crash bar.
I was thinking to run the socket straight onto the battery because of my limited electrical experience (that much I can do though).

My question: will my Rocketfish charger use up any Juice while it is plugged in when the gps is not plugged in (meaning the mini USB end is hanging loose)??
Is it possible to drain my battery from leaving the charger alone plugged in?

Cheers

If it isn't plugged in to the GPS it shouldn't use power, unless it has a light/led (for power) then it will, but VERY minor. If you leave the GPS plugged in, it will charge it, regardless of if it is on or off. Learn how to add a relay in there so you can have it switch on with the ignition, fairly simple. If you can add a 12v socket, you can do the relay, too.

If you put it to the battery dont forget a fuse. I prefer doing it this way so that you don't have to cut into any of the wiring for the bike.

I ran a wire from the battery, to a switch in the cowling, instead of a relay. I prefer have power in my socket if i want without the key in ignition. I have a LED as visual reminder that the switch is ON. And yes, dont forget a fuse.

The problem with a switched socket is that when used for a GPS, it is annoying to have the GPS turn off every time you stop and shut off the bike. I like to have it up and running all the time so I can make adjustments when I am stopped. You also then lose the use of the socket for charging things while the bike is off - charging a cell phone for a couple hours over lunch or whatever.

Yes you can. Make sure you fuse the socket to match your GPS as they draw very little amps and will not blow a 1 amp fuse ( at least my garmin 60 CX only has a 1 amp fuse>)

So that is your issue, if you want to use the socket for anything else than the gps, you will have to change out the fuse. So for example if you wanted to use a heated vest, likely in the 10 amp range or a tire pump more like a 15 amp range.

On mine I have three lines to the battery ( combined into one ground wire & two power wires ). Each one has its own fuse rated for the load it is expected to carry.

I also have a battery monitor and the GPS itself draws very little juice, so that for gas or lunch stops you don't have to shut it off, but other than that I shut the gps off.

My gps asks if I want to turn off or use (internal) battery, it's an old gps, but it lasts for a while without battery, so that's not an issue for me.
Like I said, I have a switch in between constant power and switched power that feeds the tankbag. I can make it what I want by flipping a switch. I normally keep it switched with ignition, only when I need to charge something when I'm off my bike do I use the switch to make it constant power.

I did this and had to replace the fuse at one point in time. Direct to the battery is the no-fuss option for us mechanically challenged.

Where is the best place online to buy switch, relay, fuses and power plug. Does anyone sell a kit?

Automotive stores have the parts and probably radio schlock.
If you get the connector that goes to the factory heated grip plug it's easy to run the relay off that and then wire all the accessories from there.
Then it's fused and switched. You would want to fuse any accessories individually. Like the 12 volt outlet at 10-15 amps for the air compressor that inflates your flat tire.

Thanks everyone for their input.

I ended up getting a 12v socket with a 15amp fuse and putting it straight to the battery. I was able to hide the socket up under the fairing where it will stay nice and dry.

Just had another quick question. I plugged a car air compressor (unsure of the wattage) into my factory installed 12v socket (not the one I just added) and blew it instantly. Opened up the fuse to find out that it was only 3 amps??? Is that right? You can't run very much with three amps!

Your fuse should be sized to match the wire you have used, eg; 10amp wire would require a 10amp fuse, the fuse is there to protect the wire only, what you plug in should have it's own fuse of a suitable size.
