Hi all.
Probably this topic is out there somewhere but I could not find it.
I have a 98 hornet and I want to conect the power suply to my Sat Nav (home made adaptation). Where is the best way and what consideration shall I keep in mind?
Many thanks

It depends if you want it to be switched by the ignition switch or live 24/7
…I think that been available 24/7 it is not necesary, at least it is much easier to get it done.
cheers
simplest is two wires from your battery…have a fuse in the positive and bobs yer uncle job done…you could attach it via a relay and wire it to any dvice that comes on with ignition on and that would work too but to be honest seems a waste for a sat nav…
I ran my Road Angel via a cig socket wired to the battery. Now the Zumo runs off the battery direct; both of these had/have in-line fuses, way to go.
done the same on the 'bird, wired direct to the battery socket under seat in the dry piece of p**s 
Might be a piece of p**s but I wouldn’t fancy having it live all the time.:Whistling:
true but if its for your sat nav chunks and only that then when the sat nav aint there it wouldnt be likely to drain the battery unless some knob connects his boom box to it…and runs the disco for the night…
^^^^^^^^^ wot he said 
its there and handy if you wanna charge ya phone, use an inflator for ya tyres or girlfreind if your ginge
plus its nice n dry in the battery box on my bike
Agreed but knowing me, I’d leave my satnav on when I put my P&J away for the night. I had enought grief with my blooming Datatool rinsing my battery:D
Guys the fuse…of how many amps?
too dark to check but i think its a 15 amp one let ya know in morning ok

The smallest you can get away with, it’s the safest. Look for the current draw for the satnav, or the heaviest bit of kit your ever going to plug in, and size it to suit.
It’s the old simple Watts over Volts = Amps rule. You know V = 12, Watts, or parts of, will be on the kit you want to connect. Do the simple sum and I’ll be surprised if it comes over 3 Amps with modern stuff. (Unless you want to plug a work light in.)
Easy enough to carry a couple of spare/heavier fuses in your pocket on the chance you got it wrong.
… and I maybe teaching you egg sucking, but make sure the wires you use can handle more current than the fuse is rated at. The fuse protects your bike wiring, not the device.

Thats not so daft. Once f88ked up a rear end wiring loom on a car by getting everything right except one cable on the new tow hitch socket.
Since then, I’ve worked on the basis that the cables CAN’T BE TOO BIG, only too small.
