Hey all, been a while since I've been on this board. Spending most of my time on my 1190RX. Last week, I decided to take my XB to work. Stopped for gas, got about 1/2 a block and the engine shut off. No electrical power. Messed with the on-off switch, the ignition switch, nuthin. The starter makes no sounds at all. Pushed it about a mile and a quarter home. Long push for an old guy..! Anyway, just got done checking the bar switch block (on-off and starter), all is well. The electrical above the headlights shows nothing obvious. The Battery is up over 13 volts (head lights, nice and bright). Not starter problems as that would not shut the engine off..!? Anyone have any other places to look ? Mike | ||

Did you check the fuses and relays yet? | ||

Yes, I did. The "ignition" fuse (15amp) is blown. I stuck another in after putting the bar switch back together...pop...another fuse quickly blown after turning on the ignition (without trying the starter). It just reinforced the "ignition" side of the system for me to look at. That's why I started looking for a dead short somewhere. Wire to wire or wire to ground. As noted, nothing obvious yet. And I'd think it would be obvious...just don't know where. Hoping (well...not really!) you guys may have run into a similar situation. Mike | ||

P.s. - I don't know how to check for a bad relay. Mike | ||

Switch the relays around. And if the bike is a xb-r ,maybe it's a bad wire in the ignition lock. | ||

Apples and oranges, But . . . . 01 X-1. Died while riding. Blown ign fuse. Replace the fuse, and everything would work Until turning the stop/run switch to run, when the ign fuse would immediately pop. After various things (basically, removed Everything associated with the ign and fuel circuit) I found out that if the neutral switch !!! was unplugged, the fuse wouldn't blow. Hmm. Since I was in that area, unplugging and plugging stuff, I unplugged the speed sensor. Problem Solved ! Turned out the 5V feed to the speed sensor had shorted out to the ground wire right where the harness goes into the sensor. That was causing the ign fuse to blow. I know, the speed sensor shouldn't have anything to do with the ignition circuit, but it obviously does. On a tuber, anyway. Might do to unplug the speed sensor and check. Could save you generating the pile of blown 15amp fuses that I accumulated . . . Hope this helps, Dave | ||

Hoo boy, it has been a while, but I seem to recall this being the scenario when the wires on the fuel pump on my 06 Uly wore through. I went through a stack of fuses trying to figure it out. Search 'fuel pump wires worn' on the Uly board and I bet you get a million people with problems such as yours... | ||

Searched around the front sprocket for obvious hot/burned/melted wires. Nuthin, all looks good. Had'nt thought of unplugging things. Will give that a try since a hand full of things are currently...unplugged. So far the obvious...hasn't proven out. I do know that my fuel light has been on since I bought the bike about 24,000ish miles ago (almost 27,000 now). Didn't give it much thought since it's been on so long..! Thanks for the help so far all... Mike | ||

Found it. I unplugged the fuel pump harness plug, new fuse, key...on...fuse lives..! Interesting that like I said, the low fuel light has been on (shorted ?) for over 24,000 miles, and it now, finally decides to give up. At least it was close to home when it quit. Shorted wires or bad pump ? I did a couple of searches with no luck. Anyone have tips/tricks on fuel pump removal ? The swing arm looks very close to the frame that would allow easy removal..!

Here you go http://www.badweatherbikers.com/buell/messages/142 838/776198.html?1342800189 Swing arm removal is what the Service Manual asks for, and it gives more room but isn't required | ||

What the hell... I did a coupla search's for something like that and came up with nothing usable..!? Thanks Froggy. Looked into U-Tube too. Too bad, I had just filled the tank with gas to. Now it'll go into my RX and car...one gallon at a time. Now to see if I need a pump or just reinsulate the wires. Thanks for the help all. MIke | ||

Yes, those fuel pump wires are known to go bad, it just happened to a friend of mine in California, on his 06 ully. | ||

You probably won't be able to get the origional o-rings back in either, they will be swollen and floppy and want to pinch. If you want the HD ones, Lance can hook you up. I posted links to replacement ones in the knowledge vault if you don't want the HD ones. | ||

Finally got the little XB apart. Being a Mechanical Engineer by profession...I do not feel bad in saying...what the "HELL" were they thinking. I'd get fired if I even "thought" about doing what the engineer (term used very loosely) designing the fuel pump assembly did. Actually...no I wouldn't...because I'd NEVER even think about doing, or NOT doing in this case, what the pump assy. engineer didn't do. And the quality control engineer is no better for letting it go like this. Place loosely hung wires hard against a sharp...non-deburred edge with no other protection...and the edge deburred like it SHOULD have been. And this is in a motorcycle that's "known" for its Harley vibration...Geeze how dumb. Two wires had the insulation cut but only one had been burned. The positive pump wire showed no burning, only the smaller yellow wire with a red strip. Sooo...I put some thick wall vinyl (should be gas friendly) tubing around the whole bunch and moved the wires to the round location in the extrusion. The tubing is long, so it can move up and down without falling out of position. I also cut the slot I used to insert the wire into a spiral so the wire won't easily fall out of the tube. It should be a plenty good enough repair for the remaining time I'll be driving motorcycles (I'm 66). Mike | ||

Forgot to mention - All (four) of the o-rings were fine for reinstallation into the frame and pressure line with no problem. And thanks again to the guys that offered the videos and other info. Mike |
