1986 XL600 voltage question

recently bought my first bike ever....an enduro xl600. The guy I bought it from had all the enduro parts off of it....said they rattled to much. bike runs great. the head lamp and tail lights were burnt out...and im trying to figure out the wiring to put everything back on. Also has bad battery....when i started the bike and tested with my multimeter im getting 40 volts at anywhere i can get voltage.....could this be a bad voltage rectifier? and if so could the enduro parts have been taken off by the previous owner becuase the high voltage fried the circuitry? in the components?

thanks...im completely new to dirt biking other than just a bit of riding when i was a kid


Yes it's either a bad or just not connected right regulator. The XL has two electrical systems. One is AC for the headlight and the other id DC for the signals, horn, etc.

You need a wiring diagram at a minimum. A book is beter.

Here are a few that I found on Google.

For the 85 XL600


+1 Sounds like a bad or improperly plugged in regulator/rectifier.

I doubt this has killed anything important, just blows out bulbs as you have stated.

thanks for the wiring diagram...looks complicated...i know the head light and tail light on the bike are aftermarket and neither are hooked up but once were and i have no idea whatthe previous owner did to make them work...also dont know how to hook them up to the typical honda oem configuration since its an AC system.....i dont know why they couldnt just stick to one or the other ( ac or dc) instead of both

      Changing out my fork oil on a new to me 650l. What's generally recommended for stock springs and valving?

      So I don't seem to find my specific issue so here I am asking. 
      I have a 1997 Xr600r. It was recently re-jetted and has ran really well ever since until more recently it has begun to have this issue.
      Everything works fine. Kicks right away, nice and easy. Runs great, sounds great, purs. But when I'm downshifting and slowing down to a stop, if I let my hand off the throttle that's when it just dies. I found that I can counter this by lightly holding the throttle as I down shift (so I'm revving quite a bit during downshift).  But it hadn't done this before. 
      The only thing I've done that I suspect may have been an issue on my part was when I pulled out the engine to change the valve cover gasket and upon doing so perhaps when connecting the carb back to it, I may have missed something or made a crack in the boot? 
      Any ideas? Thanks

      Hello all,
      There's been a lot of talk about how to register a dirt bike in states that don't allow it.
      I just moved to North Carolina and for the first time in my life might be able to afford a bike. I've been dreaming about an XR650R for a long time, but they're not cheap. Plated bikes seem to be more expensive too. So here's my question, has anyone tried to plate a dirt bike by adding all the necessary features and having it inspected as a custom bike? Anyone know of another way I can plate an xr650 in NC?
