    take a jumper lead long enough to go from

    bat. + and probe to black wire .

    if this is scary 4 you put a fuse

    in it.

    this will bypass any possible

    bad connections.

    Like its eager to go.
    had a Horse that was "Eager"
    But didn't sound the same.
    So I called him "Duke"

    Dfoustou, fuse seems to be fine. I also replaced it with a spare just to make sure it wasn't fooling me and nothing changed.

    Bob, I am checking voltage relative to the green wire. I checked it at several points:
    at the main grounding point,
    at the ground wire in the headlight plug,
    in one of the ground wires that leads to the front blinker wires too.
    All were the same.

    One thing I just thought of...I don't have my headlight plugged in.
    I removed it to make it easer to get to the ignition.
    I doubt it's relevant, but just to make sure--an unplugged or blown headlight wouldn't cause this would it?

    Thanks,

    Wekadog and PurpleCX500:
    for some reason didn't see your posts last night.
    Thanks for those...I'll continue trouble shooting after work. If my memory is right though, I don't think there are any connections to the red wire between the main fuse and the ignition/key.
    that doesn't mean that something couldn't have melted or been "improved" in the past.

    This is actually got me thinking of just building my own harness. I had to replace my first harness because it came to me torn up and after a couple of years of problems popping up here and there I just bought a used one off of ebay. This one worked fine for the last couple of years until now....

    I'll report back what I find.
    Thanks y'all.

    You are correct that there are no joins in the red wire between main fuse and ignition switch. ..... from the factory .....

    OK, if you have voltage relative to the green wire at the fuse end of the red wire what Wekadog said about a high resistance in the red wire sounds like a good candidate. Try bypassing the whole keyswitch & red wire like Purple said.

    Also, take a good look at where the terminals are crimped onto the red wire at both ends. It is possible that moisture has gotten int it and corroded the copper. I once had a gremlin that i chased for quite a while before I figured out that a crimped butt connector's insulation had a tiny hole from the crimping tool on the side I couldn't see and the copper was turning to green mush.

    yep...that's what I'm worried about.
    To be clear....there's no impact to all of this from having my headlight unplugged, right?

    Right. The only difference having the headlight unplugged will make is that the headlight itself won't light up.

    If it does turn out to be corrosion inside the wire it is not likely to affect more than an inch or so near the end.

    Thanks Bob.
    Looks like I've got my trouble shooting plan for tonight.
    To be clear. I should take a wire, connect it to the battery positive, then connect it to where the black wire goes into the six pin connector.
    If my neutral/indicator/gauge lights come on and I'm able to fire the bike up then I know for certain that the problem is within the red wire (most likely where it is crimped on both ends).

    Best advice for cleaning the ends of the red wire? I'll try to spray some electrical cleaner down them to clean them out, but not sure how effective that will be. I think you need a special tool to release the wires from the six pin connector, right? If you don't have this tool handy is there an alternative fix?
    Thanks,
    Blivy

    Start by taking a good look at the wires. Sometimes when the copper is corroded you can tell because, while the insulation is intact, it has an odd kink or bend in a place that doesn't feel as stiff as the rest. If you don't see anything that looks wrong skip to trying Purple's suggestion exactly as you described. And yes, if everything lights up when you do that the problem is somewhere between the fuse and where the keyswitch connects to the black wire.

    BTW: You said the new keyswitch was intended for your brother's bike. Is his the same as yours? I ask because one from a TI bike looks very similar to one from a CDI bike and the connector will plug into it but it won't work right.
