I've been watching this thread and have searched many others as I'm about to wire my XR650r and still deciding on several components. I have noticed many threads about BD batteries getting toasted, could this be due to incorrect wiring or wrong reg/rec? I was thinking of going with a battery box available through Wheeling:
Scroll down to the EZ Electric Wire Kit, you can buy the whole deal or bits and pieces. It just takes 8 AA batteries, thought that would be good if they went out on the road you could replace at a convenience store, or if the batteries went dead in your flashlight you could rob the bike. So, I was wondering if anybody had any experience with this battery box and their wiring harness, it seems reasonable enough. I have heard many good things from this company. I currently have their Edge tail light/brake light and it works great.
