    I owe a 2001 BRP and it is the version without battery. Its a kicker of course. I now wonder where I could connect the cable for my nav system (Zumo 660).
    Although I am familiar with all kind of technical stuff I am not so sure with electrics. Can I just go and look for a cable somewhere in the wiring and connect my Zumo?
    And what will happen if the regulator fails, I expect it will kill my nav system instantly.

    Thanks for any tipps and hints!

    Cheers

    There is a thread on ADV called "XR650R Electricity" that is over 50 pages long and will keep you entertained for days but you will know everything you may or may not want to know about your bike. Sorry I can't give you the link but that is above my skills.

    Now the abbreviated version :

    1) There are two types of elecrtical systems - Alternating Current (AC) and Direct Current (DC)
    Your 650R provides AC and your Garmin needs DC so you will need to convert a portion of your bikes AC to DC

    2) Stock XR650R system is big enough to run the stock electrical accessories and not much more. It puts out approximately 75 Watts power and consumes approximately 50-55 Watts - This is only the lighting load of headlight and tail light. The ignition electrics are supplied by it's own system and are not part of the lighting system load.

    I think what you are wanting to do is possible with the stock system as long as it has had no additional loads already added. I would purchase a small "bridge rectifier" at an electronics supplier - converts AC to DC- and connect it to the brown wire at the headlight and ground, then the proper garmin vehicle adapter cable to the DC terminals, you may need to add a small smoothing capacitor but I doubt it. Use caution with this as older Garmin units were able to connect to a very wide range of DC voltages - I think my old GPSV will operate on 5-40VDC but I think your newer unit is more sensitive to voltage inputs.

    Good luck and if you have a electronics buddy I would enlist their help.:D

    Many thanx for the short version :D <i am short on time these days. However, I am sure that the headlight and instrument lightning runs with 12V DC so I thought I might just.... mh.... but obviously that isnt a good idea either.

    How long do the nav systems batteries last? :1drink

    Many thanx Brian, that is what I hoped. I will go and find a DC + line to hook in the GPS. Hope that the voltage is stable.

    Thx again for the wiring diagram!

    Cheers

    I did not notice where you were - I wish our 650R's were delivered like that, it would have made things so much simpler. Have fun with a great bike.
