I want to wire up a ct1 175 enduro yamaha to only have a headlight , and the ignition was missing when I got it ...... Where do I put the kill switch ? Before the coil ? And , can you tell me where ea

Starting doesn't go through the ignition switch it goes through the starter solenoid and the ignition switch controls that solenoid only about 5 amps.

I think your bike is being powered through the starter solenoid by a defective starter button. The starter button is on the right switch assembly and normally turns the headlight off when depressed halfway. A wire may be plugged in wrong in the headlight (Two wires are crossed). Take apart the right switch assembly and check for shorts and power from the solenoid ). Check the main wire harness to the handle bar switch for crossed wires (they are color coded).

Sounds like you are missing a fuse panel. Don't forget the protection.

One of thouse wires is( battery ,acc , start , axilly ) that's your (4) wires.

ill do a list of things that can help or be the problem.

1) Pull the coil off and wire brush down all the bare metal. then do the same to the frame where it bolted on. Make sure there is a grounded wire that bolts back onto the coil if there was one, Replace the wire end for the ground peice.

2) Pull off the spark end cap and cut the wire down a few mm until you see new wire then screw it back on. (if its NGK)

3) follow the wire from the kill switch and make sure it isnt grounding out.

4) Hotwire - find the kill switch and unplug it. if this doesnt help unplug the ignition key wiring. on older bikes it will work for ignition but not lights for the key part. if this helps you need a new Ignition barrel / Kill switch.

5) check your wiring harness make sure it isnt grounding anywhere exept where its ment to.

6) make your your engine to CDI is plugged in and has no oxide in it

7) try and find somone with a running bike the same as yours and borrow there CDI, if this helps you need to buy a new CDI or check yours for wiring shorts.

hope this helps if not buzz me ([email protected])

with Steering lock on headstock and correct tank using the plug in black connector Bosch ignition - she looks great and pulls like a train.... My problem is that I am entered into an Enduro in France (I am in England) on the 14th October and the bike must have working lights.....It has a headlight and Tail light but no wiring connecting them. There are several spare wires taped up under the tank I am quite happy to carry out the wiring I just need to know the colours to use...and how to check them I have a multimeter available. It has a horn attached and I have bought a high/low /horn switch , as well as a rear brake light switch...,I have written this motoplat instruction quite a while back: http://www.ktm495.mxbikes.com/motoplat.htm Right at the bottom is the color coding for the lightning wires.,,,
