Thanks for your time and let me know what you think pleasehttp://s1146.photobucket.com/user/jakey ... t=3&page=1 There are just so many female connectors with barely any males. Sad to see what people have done to this bike. If you need better or more specific photos let me know

Need to work by process of elimination to find the issues.
Going one wire at a time, comparing what you have to the wiring diagram.
Eliminating the wires that are easiest to figure out first.

Its tedious when sitting in front of the bike if you have a wiring diagram.
Not sure how much help I can provide remotely by just looking at pics.

Start by pulling all the wires further out of the bucket so you can separate them as much as you can without disconnecting anything.

I hate working with wiring that other people have modified. It drives me nuts. So what I do is to sit down with a pad of paper and pencil and a few copies of the wiring diagram. I'll follow one circuit on the diagram and then then I'll test that on the bikes.

So let's start at the battery. Red is 12v. Do we have 12v at the battery? The wiring diagram shows that going to the main switch. Do we have 12v there at the terminal? Do we have 12v on the Orange lead coming out of the main switch when it's turned to ON? I draw out that particular circuit and if it's not the same as the diagram, That's where I have to decide what has been changed.

That was easy. Now to test the ignition circuit one step at a time. Power goes from the main switch to the kill switch and form there to the coils. test at each connector into and out of the kill switch and then at the coils?

Then test the circuit for the headlamp high and low beams. It seems daunting but it's a simple process of literally following wires and testing them.

And so on for each circuit in turn.

hey guys, my neighbor and i were out in the garage trying out a few things. He thinks its a bad earth somewhere. when the ign is on and dimmer switch on, testing the battery it drops .01 practically per second. 12.46-12.45-12.44 etc. Also noticed a loose wire that had been cut and left exposed which is connected to the metal mount for the turn signal relay, what is that for and where should it be? Thanks for your time - Jacob

What color is the wire?

That wire was solid black. Completely cut off and just hanging. Gotta love the people who just genuinely dont care, its a shame to see how it was treated its such a beautiful bike. Yesterday i took the seat and tank off, so if you guys think theres a problem there i would be more then happy to take more pictures, Thanks again - Jacob

Look at the wiring diagram that I posted.
Look near the bottom of the diagram roughly between the coils & alternator, and you will wee a ground wire attachment point.
That ground attachment should be somewhere hear the battery box.
The black wire that has been cut off could be for that ground.

Am willing to help.
Going though the wiring via pics & posts is likely to be a rather lengthly process.

Make some printouts of the wiring diagram that I provided.
With the help of your neighbor, you may be able to map out how it compares to the actual wiring on your bike. Having done that, finding the problems should be a lot easier.

I got the headlight sorted out it was the black and white wire in the junction box. Now I can't get it started at all. The orange wires are connected and I'm out of male connectors. Now what? Freshly charged battery aswell

Check to see how the kill switch is wired up.

Not exactly. It could be that one of the brake light switches in ON or that the kill switch is incorrectly wired

+1 on that.

Looks like you switched the kill switch & stop light wiring.

Look at the wiring diagram.

Orange hot wires go to both the kill switch & stop light switch.

Other wires for the two switches:
O/W for the kill switch
W for the stop light switch

Check the O & O/W wires.

When i found the wire for the headlight the bullet connector had broken off so i replaced it with another, which turned out to be too big. So i put a different connector on, the other end was a dual connection and i replace it with what i had, just a single connector. Im starting to think the orange wire was suppose to go in the other connection. I have an orange/white wire but theres no voltage going it. There is a hot brown and a dual connection female orange. When connected solid orange to the solid orange dual connection that caused the brake light to illuminate so that was the incorrect connection. So through process of elimination im guessing that the dual connection needed the orange in it aswell. What do you guys think

Hey guys. This guy came over and just told me to trace down every wire, which I feel is unnecessary. Regardless my neighbor came back over and we spent 45 minutes and there's no spark and nothing at the coils whatsoever. When I connected the orange from kill switch to the orange connector in the headlamp bucket and turn it to run the tail light would illuminate so I know the kill switch is working. Its just a matter of where this orange wire goes. The problem is I don't have voltage coming from any wires except for the orange which illuminates headlight and a brown wire when I switch the headlamp on which has also been bypassed. I'm getting really frustrated and kind of at a loss. I'm not sure hoe to check to see if the coils are bad. But they are yagusa's I bought offline. Everything was running last Friday until I approached the headlight issue. I'm just really stumped any more help would really really be greatly appreciated
