Here is a generic schematic of the electrical system of a motorcycle. As you can see there are 4 wires on the switch of this example.



Now this is just an example, but it could steer you in the right direction.

Oh and welcome to the forums.

 

yep the cylinder/key part is what i am talking about as well. On the bottom where the wires attached is where it is broke. Just replacing the cylinder wouldnt do it.

Thanks for the pics will see if I can get some time to work on it this week.
