Hey guys I have an 82 Honda Cb 450.I wired up an iPod charger a few weeks ago.it drained my battery because it was hooked directly to battery and I haven't used bike in a while.Im gonna wire it into a switched electrical source ,would the wires coming from behind the ignition be a good spot or is ignition a constant hot 12v?thanks
 
That would be fine. But... why is your charger draining the battery? Was the iPod connected?

I find the simplest route is to just wire in a 12v accessory adapter and then plug whatever you want into it. I have a dual-output USB charger in most of the time, and then run one cable to a GPS if I'm on a long trip and the other to my phone to keep it charged.

Your battery is likely pretty weak if the parasitic drain of a disconnected iPod charger killed it.
 
Tim thanks for response. I should have clarified that it is a 12v iPod adapter from burns moto.

They have a disclaimer that says over time the adapter could drain battery (miliamps). I wired it over a month ago so I guess from the bike just sitting it killed the battery. The site recommends a switched ignition source.
 
Yep just wire it in after the ignition switch. I don't know the wiring on the 450 or how many fuses it has but a lighting circuit would be good or the horn.
 
Ok cool I was actually thinking of running it to tail/brake light but the horn is right there so maybe that's better. Both horn wires are black does it matter where the red and black from the adaptor get wired to? And should I wire fuse in?
 
Don't wire it to the horn.

Tap into a black wire heading into one of the control assemblies.
 
Because it'll only charge while you're pushing the horn button.
Tap into the fuse for the headlights ;)
 
The horn button typically grounds to the handlebar completing the circuit. So power only flows when the button is pressed.
 
Both horn wires are black, though, so it's easy to get wrong. You tap into the wrong one and you'll be providing a ground through the charger and your horn might be on all the time (not taking into account the resistance on the charger, of course).
