    ok guys if anyone can help .Started running the wiring for a test run tonight turned the ignition on brake light indicators worked great but for some reason the green wire to the starter just started turning the bike over .It was on when i first connected the battery and wasnt live so why all of a sudden .The battery did get low n power.Is it suposed to have power all the time i thought it would only have power when you hit the start switch.Since it has full power the indicators wont work im banging my head right now so if you can help at all

    You're right, that green wire should only be live when the starter button is pressed.

    Wonder if it has shorted to a live wire somewhere in the harness?

    Either that or it's connected somewhere to something it shouldn't be connected to.

    Ya gunna have to trace it back to where it's picking up the power.

    Discconect both ends and trace back until you find the contact.

    Cheers rider only thing is I can see everything and nothing else besides the front and rear brake light indicators and the neutral two ignition wires and the power and earth wires too the battery. I thought it might of been cause of a low battery. Does this box come apart or if it's buggered inside u just buy a new box.

    Hi hilly I was hooking up the dimmer too the headlight and powered it up to check it and that was fine then it just started turning over. Iv charged the battery and will start tonight again. I know the indicators and tail light are right just wondering if a relay has stuck open

    Thanks for the response just test run the wiring through the frame yesterday so not everything is connected just the power wire too the ultima wiring box and the main too the starter and the main and the earth too the battery . Besides the tail light and indicators nothing and ignition wires being run too the key switch nothing else has wiring run. Would this been the problem cause it's not completely wired and all circuits are not connected.also there are three wires on the ignition switch so where does the third wire go as the other two go back to the wiring box

    It's the 18-533 without the led's the newer compact one and are the boxes supposed to open if u need to replace anything

    Cheers rider you are helping me on some of the things.the other two things are the single wire on the regulator does that run back too the battery and the neutral switch has three wires
    And only one from the ultima box

    Ofh about the dimmer it says it's the wire that runs to the handlebar switches blue

    The blue wire is power to the dimmer, (Hi/Low Beam Switch)  and white from the H/L switch is High beam, Yellow is Low beam.

     

    There is no connection on the Ultima box for the regulator so I assume that it should be connected to where it was before. ?

     

    The nuetral switch is a mystery, maybe one of the three wires is an earth. The Ultima diagram shows two terminals from the switch are bridged and connected to the 18 GA Yellow wire back to the box. 

    You will have to use a multi meter or test light to determine which wire is which and connect the one that earths out when nuetral is selected to the ultima box. The nuetral switch should earth via it's own housing,  but if not, that will be why it has the third wire and that will have to be earthed.

     

    This is the wiring diagram that I'm going on; www.ultimaproducts.com/18-533.pdf

    Thanks rider you have been a great help will let you know how I go just want to test everything before I strip it down incase I have to add any brackets to the frame .oh one more question it does
    Not show or say to run fuzes so I believed it is done in the box.should I run fuzes too be safe

    Even though it isn't stated or shown, I would imagine that the Ultima box has it's own overload protection. You would hope.

    It wouldn't do any harm to make sure, and at least install a main fuse in the Red main supply from the battery to the box, 30 Amp should be sufficient.

    As a rule, anything that is connected straight to the battery should be fused, or protected by a circuit breaker, in case of accidents, wire chaffing, short circuits, and or the like. They protect not only the electrical components themselves, but also the wiring harness, battery, and prevent the possibility of an unwanted cremation, fire.

    Thanks mate done that only wires are the power too the battery and the earth no other wires are connected at all but the solenoid wire is still live it has to be in the box itself it's bloody frustrating

    OK, so if the only wire to the battery + is the Red to the Ultima box, what you say makes sense, the fault could be internal.

    but don't overlook the fact that that same Red wire/Ultima box also distributes power to the indicators, brake light switches, horn,  headlight, and starter switch itself.

    The problem does not neccessarily have to be in the box, it could be anywhere along the line from the starter switch (right hand controls) to the solenoid, where a short has occured from any of those other powered wires.

    Make sure it isn't any of those before you take the box back as faulty.

    Thanks rider I checked the power wires too the indicators and there is no power at all only the main power wire too the start switch that's what's making me think it internal as there was power to start with too the indicators and none to the start solenoid then once i hooked the hi mo beam up something must of happened and it changed like when you engage the starter your indicators don't work so if I knew I could open the box up I could check cause if that solenoid wire doesn't have power the indicators should work. There Is four screws under the box but it doesn't seem too open once I have removed them

    Yes mate they are all labeled so there is no confusion that's what's pissing me. I'd say something has locked on in the box itself as when I first made it live the solenoid wire had no power and all the brake tail and indicators were working perfect then I connected the headlight up and after that the indicators would not function and there was constant power too the solenoid wire so I have disconnected everything but the power and earth from the box too the battery earth too the frame and the solenoid wire is live it's like the switch is constantly on in the box . Searching to find if the box can be opened thought you would beable to replace parts if they went faulty

    Just a suggestion, remove power from battery to box. May reset itself (if protected) like an auto circuit breaker.???

    Thanks als1200 I have removed the wiring and made sure everything is right so fingers crossed when I start hooking it back up it's fine.

    Power connected to the box,

    box earth lead connected,

    the IGN switch is off  ? (even if the IGN switch was on you would expect power to everything other than the soleniod wire)

    but there is still power to that damn green solenoid wire.

     

    If that's the case, as you suspect, then you would have to assume that something in the box is not right now.

    If you open it up there is every chance that Ultima will not honour any warrenty.

    Think it might be time to take it back and ask questions.

     

    Everything appeared to be going OK untill the headlight Hi/Lo switch was connected. Ever since then, nothing has been right.

     

    Edit note:   Typing at the same time as you.  hope als suggestion works,,, but why in the first place?
