I have copied my original post from the KV to here in the hopes of getting more exposure. Sorry admins, but I just need input. Here is the original link, followed by the contents of that link. I would appreciate if anyone has any ideas about my issue-thx: http://www.badweatherbikers.com/buell/messages/384 2/468244.html?1245032380 Heeeelp!!! I am stumped by my current bike issue; I have a 2004 XB12R and I was replacing a couple of things on my bike. The previous owner did a real hack job on the wiring harness, but I thought that I would replace all the hacked up parts. I redid the headlight and tail harness. I removed 1 of my 2 HID headlights and reinstalled my undertail with all new components. I was testing everything that I connected or disconnected with a multimeter to make sure that I didn't screw anything up and all was fine. So I connected my undertail and did a final mock-up before securing all fasteners; I added 2 small 12V safety lights (connected via brakelight switch to a flasher relay) and pulled in the front brake to test it. The flasher relay made a buzz which is to be expected with a small load on a flasher relay, and then the buzz from the relay stopped after maybe 10 seconds. (Dammit!) I left things as they were and checked the voltage to the brakelight switch. It read 12.3v to the main taillight (That's good), 1.3-2.1v to the switched light. (Oh no!) My brake light was not flashing, and my relay no longer fired. I checked to make sure that the spades were touching the bulb and the harness was jacked in fine; they all checked out! Strange that my undertail worked ALL THIS TIME and then stopped 10 seconds into the final mock-up without me touching or doing anything! In the interest of diligent troubleshooting, I switched off the power and turned the key again-this time the dash lights and tail light were completely out. The engine started fine though...very strange indeed! Being that I was simply reassembling a previously working system, I can not see where I might have screwed this up, so it is very difficult to backtrack what I might have disconnected or bumped into, but I tried my best. I got 0 voltage to the tail section that I can remember and I don't even know where to begin with this damn shrink wrapped harness! My headlights work fine! I had the front section disassembled to try a new wiring configuration for my HIDs, but I reverted back to the original because it made more sense. There is no issue with the headlights, and even though I get no dash lights, when I flick on my Hi Beams, my Hi Beam indicator on my dash DOES light up! That tells me that the dash is not dead, nor is its harness. (that I can tell...) I am pretty desperate here! I do have a service manual and parts manual, and I am trying to make heads/tails in order to bolster my troubleshooting efforts, but I REALLY don't want to change this whole wiring harness because of piss-poor troubleshooting on my end. Sounds like I'm panicking-can anybody help me out here?! I appreciate it guys! |

Check your grounds, obvious I know. There are two screws under the fairing support and above the lower triple tree. Those are the grounds for the instrument panel. Bypass your relay and see what that does to the rear lights. Do one thing, on one end, at a time. At the back of the manual is the wiring diagram for the lights. Study that. |

Thanks archangel, for the tip. I fixed the issue. I think after the panic leaves, logic begins to set in! So... "I left things as they were and checked the voltage to the brakelight switch...I switched off the power and turned the key again-this time the dash lights and tail light were completely out." After some logical study of the entire wiring diagram, a problem at ground 3 caused issues to run through the dash, and an intermittent connection on the new tail harness (socket seated incorrectly) caused several fuses to blow, which would explain why each time I turned the key, something new failed each time. I didn't reseat the tail light harness during the last mock-up, so that makes sense! Cost me 2 dollars to fix fuses Yaaaaaay!! |
