I wanted to hardwire a USB adapter by my handlebars. I found power from a spare yellow wire coming from headlight. Do you think I could use a ground bolted to the forks?

 

most likely will work, use a multimeter and check the ground to a known good ground. should be below 2 ohm's

 

Never thought if that. One side of the meter to the ground that I want to use and the other side to what? Thanks

 

I always read that you are suppose to wire accessories directly to the battery.

 

A better way to do it is hook up a battery charger pig tail to your battery. Then plug a USB cable into it and route it appropriately.

Number one, you avoid hacking into your wiring. Number two, the battery charger pig tail will come in handy to maintain your battery in winter or charge it up. Number three, doing it this way is very easy and cheap and virtually eliminates the possibility of a bad connection or a connector getting loose.

 

Deltran makes a usb charger that plugs right into the battery tender pigtail

 

Thanks for the tip. Looks good.

You could but that's the kind of thing that comes back to haunt you. I'd use a pig tail or direct battery connection.

 

I have A battery tender connecter but its not by my handle bars. I want to put a connecter like that near my handle bars then plug the UBS adapter into that.
