I want to hook up (charge) my iphone AND my radar on my motorcycle. My radar is already wired to the 12v cable in my bike. Now can I hook up the iphone to the same cable? or is it gonna be drawing too much power? thxI was planning on buying the cigarrete lighter thing, and pluging the iphone into that. I'd obviously hook up the cig lighter to the 12v cable.
Splice into the wire of each device, an in-line fuse holder. Use a 10A fuse. Every wire on your bike can handle 10A If a wire were to draw more than 10A the fuse would blow before any damage were to occur.
Should be ok. The current draw of these gadgets would be minimal,I would guess 5A tops
Yes. Personally, I'd leave the damn phone off and in hiding. Just ride.
Basically no, they are better wired separately unless you calculate the load. A ciggy lighter socket is not water proof so find a proper bike socket. BMW do them, You need to work out what the total load of these 2 are, and check the output of your alternator and the capacity of your battery to make sure you have enough ''spare'' power. What make of bike is it? What's the battery capacity and the output from the alternator. Electrics on modern bikes are usually good enough for accessories, I run 100w headlight 2 x 50w spots, sat nat phone and audio, not always all together, so do some sums on what power you have otherwise if it's only a small battery and alternator you could run the battery own whilst riding.
How much power you can draw from a wire depends on which wire you tap into. If you are planning on a cigar lighter type power outlet I would wire that directly to the battery, using two wires, with it's own 20 amp in-line fuse on the positive side. The one I have is weatherproof, mounted in one of the side covers.
