Hard wiring Tom Tom rider

Col, if you wanted to still switch your mount on and off, you can switch the signal to the relay instead, although the relay will have power to it all the time it won't be energised until the signal energises it.

When I ran a GPS on my SV I spliced into the position lamp rather than the headlamp.
YOu could also change the 5w wedge for a LED version if worried, that will offset the power the charger consumes.

If the TomTom Active mount has a separate cable, I'm just going wire that cable into a cigar lighter plug and use the cigar socket. Then I can move the mount between the two bikes which both have permanently live cigar sockets. With a 8-9 hour battery life, I'd only need to plug it in once every two days, then unplug it again once charged. As I wire my cigar sockets permanently live, it also means it can continue to charge uninterrupted on the bike at stops and next to the tent in the evening too.

Does the cable unplug from the mount then? If so I won't bother with the switch, I'll wire it off a relay and like you only plug in the cable when it's needed.

Yes the cable unplugs from the mount.

No, constantly powering it through the mount won't do your battery any favours, you only want to charge it when it needs to be charged. Also the first 5 times or so that you charge it, do it in the house off the 240v charger, and leave it a good 8 hours at a time from fully discharged (leave switched on and on the windowsill to discharge it fully after your ride if you need to).



Do you have a multimeter or any experience with electrics at all? If you are wiring a relay under the seat, the nearest live feed to use is probably the feed to the rear brake switch.

I wired my hotgrips into the main loom but that's about the extent of my electrical talent. I am reading up on relays and multimeters though

UPDATE.

Hi all,

i have rigged up a relay to power the tom tom following this guide http://bolty.net/2008/10/21/sv650-mo...ibution-block/

everything went fine until i tapped into the number plate light. the relay clicks open when i turn the key and power comes through but only when i have the lights on? and if i switch between high and low beam the relay clicks each time??

Thinking i had tapped into the wrong wire to the number plate light i spliced into the other and now the relay does nothing when the key is turned regardless of the lights being on or off??

just realised the guide i followed is for a pointy ( lights on constantly, no option to switch them off???).
Is this why im getting the symptoms i described above?
As i have a curvy do i need to tapp into a live that is on all the time once the ignition is on?
If so where would be a good place to tapp into?

thanks for your input guys.

One would assume that the relay only works when you switch the lights on, because that's when the wire becomes live?

On the other wire not working at all, have you tapped into the brake light wire perhaps, so does the relay work when you operate the brakes?

yes, but i thought one wire was live all the time?

i dont think so as both the wires i tapped into were to the same connector?
the number plate light also wasnt on when i dissconnected this connector.
Also this connector was a lot smaller than the brake light connector?

Yeah you need a ignition live, in other words one that's a constant live once ignition is on, just a case of testing a few until you find one.

Well at least you found a way to switch power to the mount!

Well that's the extent of my electrical help Big Chris

I tried to use my Optimate chaging lead connector under the seat as a semi permanent connection using some of these on the end of my TomTom wiring.

Would have worked, had my Optimate lead not been buggered somehow, as everything I've connected to it hasn't worked, penny didn't drop until I connected my Autocom directly to the battery.
