Been playing around with lectricks and put a direct link to the battery on Dolly. Protected it with an in-line fuse and found a nice neat little spot for it :-)
Can you see it??? No, well here's a close up
1/4" phono jack stuffed in the airbox. Now I can run all manner of 12v thingies off my bike. Don't know what exactly, but something will come to me I'm sure.
Oh, and i can charge the battery too, without all the faffing about with sidepanels :-)
