A bit of luck

The sat nav on my bike (TomTom Rider 550) is a great bit of kit but I always power it through a USB cable into a socket at the back. There is a cable attachment dangling down from the mounting but I've never got around to purchasing the, rather expensive, cable to connect it directly to the bike battery.
Where the 'bit of luck' comes in is when I got the original box out to look at the user guide for an operation on the TomTom. Lo and behold I found TomTom provide the cable in the box so it's been sitting there for all this time. I think I bought the Rider 550 a couple of years ago.
So now it begins, quite straightforward in theory but;
1 - Prepare to remove the seat - there's a large bolt which attaches the rear of the seat to the rear mudguard of the bike. Not very easy to get at since if have a luggage carrier with the top box attached so it's just a bit fiddly.
2 - Remove the seat - Wish I had a bit more muscle sometimes as to remove the seat you have to grab the back of it and push it towards the front of the bike to disengage it from that large looking spindle on the left in the top photo.
3 - with the seat off you now have to remove the - and + nuts on the battery so you can attach the wires of the sat nav. With a Harley you have to first (a) switch on the ignition (b) remove the main fuse to kill all the power.
If you don't do this the very loud, screeching, alarm will trigger when you disconnect the battery.
4 - attach the red and black cables to the battery - & + terminals, remembering to also attach anything else that is already taking power from the battery, in my case I have an adapter on my handlebars which contains a 'Cigarette Lighter' socket (not much good on a bike you might think but very handy for plugging in an electric tyre pump). It also has two USB sockets which I use for my bike camera, and the sat nav, until today.
5 - feed the wire underneath the fuel tank so it is not flailing around loose when you are riding, this involves removing the tank bolt, propping the tank up on a block of wood, feeding the wire through and then securing the tank again.
6 - replace the main fuse and get the seat back on securely.
Job done.
To be tested tomorrow when I ride to the National Memorial Arboretum for the RBL Riders Memorial ride when we have a service to remember those Riders that we have lost over the past 12 months. A sad occasion but it is one that is very important to us.
