Has anyone tried connecting the GPS power socket on the CANBUS wiring, as seen here into a SW_Motech powered tank ring as seen here.

Seems to me a great solution for hooking up gadgets in your tankbag without upsetting the CANBUS. Anyone tried this?
 
It will power up, just like any other electrical device.

If you run it directly from the battery (not the best way, as it will always be live) don't forget to put a suitable fuse between the the 'ring' and the battery.

Power it, perhaps, from the auxiliary power socket in the beak, perhaps? Or find some other suitable, switched, feed.

Here's a much better picture of the whole thing: http://www.bikegear.co.za/att/tankbag electric.pdf

This looks like a simpler system and can be attached to a whole variety of bags and panniers.

On the SW Motech system:

I am not convinced how usefull the internal light for a tankbag would be, once the bag is stuffed with clutter.

The lit up map? Not convinced.

I guess the advantage lies in that you just clip the SW Motech bag an and off, breaking the connection, with no wires.

PS I read on the bigger presentation above that the SW Motech device is already fused.

PPS If you want to charge muliple electrical devices at once, and also want to avoid carrying multiple mains tranformers around as well, the best thing on the market is still an iGo. http://www.igo.com/home.asp I have been using one for years and it's faultless; the one true 'One size fits all' device.

I would say it's unwise to go this route as the GPS Power Socket is designed for a low current draw i.e. a single GPS device. Connecting a number of 'gadgets' to this power source will either result in the CanBus shutting it down or a blown fuse.
I would use the fused power lead provided with the SW Motech powered tank ring to connect direct to the battery or an aux power distribution box/fuse panel.
 
Thanks!

Great, just the sort of advice I needed. I will look again at powering up the tank ring. Thanks for the advice.

You can draw 5 amps from one of the standard 1200 GS BuMW aux sockets. Just how much power does a phone, plus a GPS, plus an iPod, plus a charging camera draw?

Answer: A lot less than 5 amps.

I have charged, simultaneously, all the above, no problem.

According to the blurb on the transformer, my camera, at 100v draws 0.12A and and at 240v draws 0.065. Let's say 1 and a bit amps at 12v.

My phone draws 0.15A at 100v, let's say 1.5A at 12v.

Still not getting close.

Even being cautious you should be well within the limit. This of course assumes you have enough leads to charge all the devices at once, whether you run the supply direct from the battery, or via a separate switched spur.
 
Hi, I have fitted this self same item to my 07 gs.

Bit fiddly getting it under the tank without taking it off, I too the plastic box/cover off the little fuse board.

Located the fuse 'box' underneath the seat, just behind the locking mechanism, needed to loosen the bolt on the rhs of the mechanism to get the circuit board underneath.

then routed the live and neutral pair back to the battery.

Not saying this is the best way, certainly one way of doing it!!!

The CanBus socket sounds like a great way, much easier etc...

........but the original question related to the GPS/SatNav power socket not an Aux power socket and I doubt that has the same specs.

Indeed so. :thumb2

Wasn't there a chap, linked from your excellent website, who was running a radio and a GPS from a similar Canbus GPS / Sat Nav power socket, without too much problem?

It wouldn't do too much harm to try it, surely?
 
:o ......now I've got to go and check my own website, my damned memory :blast

......It wouldn't do too much harm to try it, surely?
I'm one of those 'play safe' guys when it comes to these things - I either want input from a techy/expert type (what is that GPS power circuit rated at? :nenau) or the knowledge that it's been done and was safe....now back to finding that link you're thinking of! :)
