In a little more detail. DISCONNECT YOUR BATTERY! then remove your headlight. Nearly all of the wiring in your bike runs through here. Very carefully inspect the wires and connections for corrosion or breaks. DO NOT DETACH ANYTHING UNLESS YOU KNOW WHERE IT GOES! Or unless you want to spend the next 2 weeks staring at a wiring diagram trying to figure out what all the wires are for. Check every connection. Wiggle it a bit to ensure that it is secure. If there is corrosion, carefully detach the connection making a clear note of where it came from, and clean connectors with soft metal brush. If any of the wires are actually broken, consult someone with electrical experience. Hope this helps - Rebekah
