Can't help with a wiring diagram. Lots of bikes built in the last couple of decades are fitted with an immobiliser and they are far from trouble-free. The first step when the engine doesn't start is to check the immobiliser is disarmed - if the bike is equipped with one. Often that information is found only in the owner's handbook or at the dealer. Although wiring harnesses aren't very long on bikes there is usually quite a lot of it and manufacturers don't make it any better than it absolutely has to be and there are places where wiring can be stretched or chafed and where it jumps from the frame to the steering there is lots of flexing. I suggest you expose as much of the wiring as you can and inspect it carefully for signs of damage. Check whether the fuse(s) are ok and have power on them will give you a start.

Whether or not the parts link listed above might also have wiring diagrams available would require contact with them. You might have to inquire with a dealer for such if indeed them have such access.

Have you checked your battery, sounds like it's dead to me (engine making the power once your going). Might be corrosion on your terminals too? Test your battery with a multimeter. Good luck.

Should be a dipstick up in front of the fuel tank. These have oil in the frame and use a dry sump oiling system. Run it for a few minutes then check. Only holds about 1 litre of oil total so don't overfill. It will only show oil on the dipstick after running a bit as the oil needs to be pumped around the system to be accurate on dipstick reading. --

The cable for your speedo is probably really loose, about to fall out, so tighten it.

look at the owners manual which no doubt is on-line if you don't have it.

Maybe you can find your manual on carlselter.com. I found a lot on this Web site. Good luck.

Well the horn could be very well grounding out and causing that problem or there is a faulty wire or short running with the horn check all connections for corrosion as well and clean components and re connect everything to see if it stops your problem
