2014 xc300R DC and Light Issues.

[Homerocks1]

Hello All,

I am not metering any voltage on the DC side of my regulator/rectifier. Here's what is going on...

I recently purchased a 14' XC300R without electric start. The bike runs great, but neither the headlight, running light(the small light under the headlamp inside the bezel), or tail/brake lights are working. The bike does not have turn signals, horn, speedometer, battery or electric start. There are also no controls on the handlebars for anything other than an engine kill switch.

After downloading the wiring diagram and beginning to trace wires on the bike, I have found that behind the headlamp, all of the connections were simply disconnected, and it appears that they may have been connected to handlebar controls at some point. Did they make this bike as mine currently is or did the previous owner remove all of the handlebar switching? The tail/brake lights were disconnected from the harness too. I will have to make my own contacts to get everything to work, which isn't a big deal.

The problem is that while the bike is running I am metering 20-21 volts AC on the stator side of the bike, but I am getting no DC voltage on the DC side of the regulator/rectifier. I have metered various DC+ to various ground locations. I also metered the contacts at the regulator/rectifier. The results are still 20-21 volts ac and no voltage DC.

I don't see any fuses anywhere and the wiring all appears to be in pretty good condition. Is there a way to check to see if the reg/rectifier is bad? Because there are exposed DC+ wires and connectors just hanging behind the headlight could they have shorted while touching the frame while riding thus damaging the reg/rectifier?

Thanks for any help. I started reading about AC/DC systems in bikes just yesterday so I'm not very knowledgeable on the subject.
