    Looking for some help. I am not a mechanic and I don't have much experience with bikes, however, I do understand electrical work. I'm trying to track down why my 2007 Norge isn't starting. I believe its an electrical problem. And I've been trying to track it down. (It might be an ECU issue).

    Important to know that my fuel pump does work. We mounted the gas tank on another bike and it ran perfectly.

    Now back to my bike.

    I've tested the individual relays they all work on their own. All the relays when the control coil is activated they close the switch portion of the relay. I tested them all (primary Injection, auxiliary, ignition and even the lights). With the relays inside the Norge, I:

    a) cannot start the bike with the starter button (hint that the ECU would be involved)
    i) when I took to the starter button apart, it seemed to open and close correctly, but to truly test it I need to test pin "28" on the ECU to see what signal is provide. Getting to the ECU is another big issue.
    b) I should also note, that the primary relay comes on when the key is turn to power. So I believe power is at the starter switch
    c) When I close the control circuit on the ignition relay by grounding the Pin "1" side, the bike turns over
    there is no spark though......also pointing to an ECU issue
    d) I've check all the sensors (clutch, Neutral, side stand) they seem to open and close correctly. (I just don't know what signal is present at the ecu pins.

    Is there something else I should have checked?

    Now, I have stripped the fairing off, disconnected the lights, removed the gas tank, and am now looking to both disconnect the connectors to the ecu and remove the ecu from its very tight spot. So far, I have spent 2 or more hours trying either to remove the ECU or disconnect either of the two connectors. I just don't understand how to get that damn thing out? Any ideas, pointer or pictures of someone removing it from the Norge?

    Any help would be appreciated.

    Hang on I've got some pics, back soon!

    Here it is, you can see how the clip engages and disengages in the pics. It's a bugger for sure.

    MIke, It looks like the clips to lock the connector in place are behind the round part (ie) towards the middle of the ecu. Do you push the locks inwards to unlock the clip? I have some work to do to get that ECU out. I just don't believe how tight it is...amazing.

    The clips are identical in operation to the clip holding the dash board connector in place - except that you can see the dashboard connector so it's a good place to look and get a feel for how they operate. They are a PITA to get at but it can be done. Cursing helps!

    Cheers
