    Where did you come up with that wiring diagram????????? It doesn't look right........ Also what is all the masking tape for????

    Plus if the bike is lunging forward when you crank it you have other problems........... That has nothing to do with wiring............

    get a FACTORY manual for your year & follow the wiring diagrams in it,
    they break it down to various circuits not just the whole spaghetti wiring,
    real easy when you have the book,
    plus if you search the interwebnet, you will kind Large scale, laminated diagrams in full colour so a lot easier to read,
    making up ya own diagram only works if ya know what ya doing & what every wire is for,
    I have been building & wiring Harley since the mid 70's & still ALWAYS refer to the manual or enlarged diagrams.
    the diagram you have on youtube isn't clear enough to see what ya doing, but as said, something looks a bit hookey, scan it & post it here so we can see where you went wrong...

    the masking tape is just to get the wires out of the way and a little neater for the meantime.

    it lunges forward not when cranked but in the 3rd position (ignition)

    1st position being BAT, which it stays on, next going left which is ACC, 3rd going 1 turn from BAT which is IGN, and 4th being the spring start (2 over from BAT)

    Can I ask why you have the same 2 colors of wires running every where??
    What happened to the original harness????
    You really need to start from the beginning why did you start messing with the wiring in the first place????

    Are you trying to make a car type switch work????? A spring start?????? What's that????

    I'm not digging on you just trying to understand so we can help you....... But you really need to throw that wiring diagram you made up in the trash........

    Way more info needed.......

    Ok I missed the pink one so there is 3 colors red, pink and white..... And the green one that you can't hook up..... I'm talking about the wires you have masking taped down.....

    They sure don't look like original harness wires........ I've never seen Harley use yellow wire connectors.

    So your simplifying it by using a car starter switch???????

    Best of luck..........

    You have, in the lower right side of your diagram, what looks like it says, 30A breaker, and it's grounded. THAT WON'T WORK!

    Most everything else looks OK except the power feed to terminal 30 on the starter relay. That should be breaker protected in some way. (I like that feed from the load side of the main breaker, so always hot.)

    The connectors arenít stock but everything else is.
    As far as simplifying Iíve actually done a lot. The momentary key switch bypasses a start switch. I also did away with the front brake switch, blinkers, instr. cluster including tach, speedo, horn, emergency stop switch, and bank angle sensor

    Okay so isn’t my terminal (relay) 30 protected bc it’s going from ACC switch then being relayed into a 15A fuse then going to headlight, tail light, brake light.
    Relay 30 is accessories. Isn’t relay 87 coming from the starter in the problem?

    Here’s the HD diagram…
    I see here that one of the 87 relay terminals is being transferred from all the others (85, 86, and 30) so maybe the problem lies with one of their faults in my wiring.

    Isn't the bank angle sensor incorporated into the pickup/module on a '00 XL?

    If the starter motor is turning over, the green wire to the starter solenoid is being connected to 12V by some path. That's the only way it could happen.
    Your new ignition switch could be faulty.

    By the way, if the ignition switch is robust enough, you can do away with the starter relay and connect the green wire from the starter solenoid directly to the start post on the ignition switch. You would be best served by using 14ga. wire to supply battery power to the ignition switch, and for the green wire to the solenoid, if that is what you decide to do.

    My question about the 30A breaker, above, still stands. It WON'T WORK the way you have it drawn.

    My bike actually didn’t have a bank incorporated! It was on the right side of the battery case.
    The green wire i have iss 14 gauge and the switch terminal is rather robust. So you’re saying i can and should go straight to the spring start position on the switch?
    Now without the green going to the relay it then takes the gray wire’s place and i wouldn’t have anymore use for relay 86 correct?

    As for the breaker, it has a black wire going to the starter. That i didn’t mess it nor remove.

    Thank you for your guidance

    New diagram would be…Click image for larger version.
