    Neutral light issue

    Assuming you have an earlier XB (< 2008) it sounds like you have the diode in the fusebox inserted the wrong way around. It is a thing that looks like a fuse but has a symbol on the top that is similar to '->|-'. This is a picture of the fusebox layout of my '06 Uly - the layout may differ with...

    Fuel injector wires (?) chewed by mice.

    The manual has some info on removing & fitting the sensor - it is in the Fuel System section (see page 4-98/99 of the .pdf linked in one of the posts above). I've not actually done this so can't help with any 'gotchas' but the manual does at least list a special socket that you would need -...

    Fuel injector wires (?) chewed by mice.

    Something has gone awry with your last attachment but looking closely at your first picture that wire appears braided on the section that is out of focus so I think you are correct about it being the temperature sender. These early ones had a black, braided outer but I can't vouch for the...

    Been gone long time, stator question

    Unfortunately yes, all the failures I have seen with this (my own '06 and at least 4 or 5 I have done for other people) all started with the female sockets being spread slightly so there wasn't a good firm seating of the male pins. In some cases the resulting resistive connection created by...

    Been gone long time, stator question

    I haven't been on for while but looking through your saga here I would be inclined to suspect the dear old 77 connector that is the DC output of the earlier VR. They definitely can get a carbon buildup from arcing in spread female sockets that effectively insulates one of the pis from connecting...

    fuel pump will not stop running

    The fuse box diode is a pre-2008 item that provides isolation between the clutch switch and the neutral switch - this is handled by the ECM in the 2008-2009 so not fitted (I have no idea about the 2010). I will have a further dig into the pump wiring on my 2009 Uly later today but in theory...

    fuel pump will not stop running

    John, please excuse the interruption - the power for the fuel pump is indeed switched in the pre-2008 XB's and is shared between the fuel pump and fuel injectors, sensors but in the 2008-2009 models it is hot via the 10A fuel pump fuse (and the 30A battery fuse). I just went and physically...

    Lightning short gremlin

    The one area of suspicion for a high current ground short is the starter motor cable going to the battery positive as mentioned in the previous post, therefore this is a point to look into - I'm not familiar with what this is - I have seen the push buttons that mechanically push the solenoid...

    Blowing 30A fuse - When Hot or Not?

    Nice work - I'm with Eric O looking at that.

    Blowing 30A fuse - When Hot or Not?

    This is a photo of the Uly main diagram from the 2009 Electrical Diagnostic manual - not sure if it there are any major differences to the earlier systems in the main fuse area but these diagrams are colour coded so possibly easier to follow if you aren't into electrical diagrams. One thing...

    Ignition switch question

    The XB ignition switch contacts can get grotty and because the ignition switch is essentially two seperate switches ganged together you can get this odd behaviour with intermittent contact on the multiple fixed contacts internally. The electrical part of the switch was available as a spare but I...

    Lunatic happy birthday

    Happy birthday John - all the best.

    Is this bad will it damage anything?

    I dropped the nut from the front ECM bolt which isn't that far behind where you are showing in the photo. I looked all over the place and eventually found it sitting on the top of the belt under the front pulley cover. Very possible for things to bounce in via the rear of that cover so for the...

    I have sent you a hand drawn simplified circuit and a few steps to follow via PM - hopefully that will help.

    04 XB12R- 64K Electrical Issue

    No - only to the +ve DC side as mentioned above. "I checked the rectifier/regulator internal readings using diode mode as you have done and I get a very similar reading between each AC input and the +ve DC output - 0.455v one way and open in the reverse direction. I get nothing measuring to the...

    04 XB12R- 64K Electrical Issue

    I checked the rectifier/regulator internal readings using diode mode as you have done and I get a very similar reading between each AC input and the +ve DC output - 0.455v one way and open in the reverse direction. I get nothing measuring to the DC -ve. This was on a brand new Buell regulator...

    04 XB12R- 64K Electrical Issue

    I can't recall what internal resistance measurements of the regulator show (I have done those measurements in the past as I have a faulty regulator here that I started to dissect with a mind to repair but it is presently in the 'get around to it' box). I will check a good regulator today and get...
