Another thread prompted me to check if I was getting any rubbing under the seat. Yep, quite a bit. Stock, '06.  | ||

Holy worn through wires Batman! I thought mine was a fluke, but look how serious your rubbing is. You are right, everyone should check their wiring. | ||

This is the same problem I'm having only there is damage to the ECM. Check your seat pan for rub marks indicating what all is being rubbed to death. | ||

Yep, I've got quite a bit of rubbing on the ECM just outside the picture in the upper left. There is a nice rubbed off section of the bottom of my seat too. Not a big deal, but I wouldn't want it to cause any problems. | ||

Take a look under the air box and check out the arrangement there. ET and O2 sensor cross form a shaking engine to a fixed frame. Some time the wires are banjo tight and some time they are just laying on the hot rocker box as it rocks back and forth. I do not think much of the quality of the wires. The wiring harness is a weak link on this machine. Sidestand is a close second............I know I shouldn't....but as for the fan, the fan sucks because the scoop won't scoop. | ||

does this only happen to fat people are all people/ J/K | ||

ok, i've checked and found the same problems developing. 2006 low seat. 1500 miles on the bike. had it since july. fyi i weigh just under 160lbs with boots and gear! you can see the pic....i've got initial rubbing on ECM, wires, seat, engine, etc. fyi, i added the Oly kevlar heat shielding about 900 miles, so perhaps that has helped minimize the rubbing? all miles have been on the 2006 low seat. agree that Buell needs to address this or there could be a grundle of bikes with serious electrical problems down the road.  | ||

My wires are good. :-) | ||

AZm2, I studied your photo and you've created your own wire rubbing problems by propping up both the positive cable to the battery and all the ECM wires that you show with your added wiring. That plastic thing under the positive cable is not stock issue and neither are the two looped heavy gauge black wires that have worn insulation. The yellow wire showing insulation wear through is higher than it should be because of your added wiring. Do yourself a favor and rearrange your mods so they allow the stock wiring and cable to lay where they were intended to lay and that is lower than where they are shown in your photo. The ULY probably does have some wiring problems but let's not cloud this issue with self inflicted wounds. | ||

Electraglider, I'll give you the benefit of the doubt on the battery cable. I can see how the heated vest wire fuse box could prop up the cable and cause more friction, although it slides in and out of there pretty easy. And I'm not concerned about the black wires that I ran, I obviously didn't route them low enough. The ECM wires are a different story, I didn't do anything with them and they aren't propped up at all. To address the problem, I'll press them down to get them lower. But as far as I know, they came that way. Take a look at this pic and the female socket into the ECM. You'll see the rubbing and that the pressure is actually causing it to break away. That's obviously in stock location.  | ||

I wonder how many of the bikes that die mysteriously have that same problem? | ||
| Dragon_slayer |
If my ECM dies from this problem and the stock ECM is out of stock, do you think the dealer will install a race ECM under warranty? Maybe I should only ride very far from home and plea my case about needing emergency far from home repair! | ||

Your positive cable should not go under the ECM wires but to the right of them same as in Chinooks photo above. I checked the sames wires on my bike and I notice what I assume are assembly mars on wires by what looks like finger nail scratches on wire insulation in 3 separate spots. Just scratches not scrape throughs. I just thought it was interesting when I started checking my own bike out. Another thought is that depending on where you sit on the seat there is possibly more or less deflection of the seat. I sit forward and never on the wider part of the stock seat which for me is just too far back and I've got pretty long arms. I weigh 205 lbs. If you push down on the seat with your hands over were all this damage is occurring you'll notice that the seat sinks down and I'm sure the seat pan deflects also. Probably should have designed a larger space for the ECM. | ||

Wow, This is pretty scary stuff. I just purchased a lower seat. I tried someone's suggestion from some thread, to use a slice of bread to see how close it is. It was darn close, so I placed a piece of duct tape, sticky side facing the top, to see if it stuck to the seat, and it did. I tried moving the ECM around, could not do so as the wiring harness does not have any slack. So, I flipped the ECM, i.e. put it upside down, the ECM from factory has a flat side in the bottom and about 2 inches going North, so by flipping it upside down, it moved about an inch down, so there is about a inch of clearance between the seat and ECM. What I plan to do is to get some insulating cloth and wrap the wires going into the sockets to condense the harness. Then I will try to find a anchor so to lower the wires. Will keep you guys posted. Thanks | ||

Mannu, you were able to flip it over and it bolted back up correctly? I suggested that idea in Panhead-dan's ECM-problems thread but I didn't think it could be done without carving into the shock tunnel, but I was just eyeballing it. That would seem to be a good way to handle it, if the harness cooperates. Personally I'd rather see the ECM behind the battery, there's lots of room under the Uly seat. | ||

I would second that suggestion of either getting a longer harness, which I dont think anyone makes or cutting all the wires and throwing in the needed wires to extend and place the ECM after the battery. You are absolutely right. After flipping it, the ECM and mounting bracket are out of alignment. Since the bolt would not have worked, I used a plastic tie. They are might durable and give enough room for bounce and flex. I have had this configuration for about a week. I will share my observations, hopefully they are all good. Ride safe | ||

Mammu, Interesting idea. If you decide to extend the wires there are one or two that you might want to put a switch on. | ||
| Mannu |
Davo, I havent mapped all the wires yet. Which leads did you have in mind... And what is their purpose.. I rode the bike today for 2 hours, over rough terrain. I am in Cali, and the temperatures get pretty ugly, so I wanted to see how the bike would do on rocks and pebbles. Looks like the plastic ties are doing the job. But I think relocation is a better idea. I will try and improvise and take notes of my findings and share them. Later everyone... | ||

Mannu, If I were extending my wires I would put a switch on O2 wire (pin 4 of gray connector) and the VSS (pin 9 of gray connector). I would do this for testing and diagnosis purposes. I have found I can freeze the stored AFV by removing the VSS before the ignition is turned on. The closed loop AFV feedback can be locked to the same value if the O2 wire is disconnected prior to the ignition being turned on. Do not disconnect the O2 after the ignition and engine are on or the AFV will go to the lowest number around 82 and stay there. This will generate a very lean condition. I would not recommend anyone doing this without a wideband sensor in place to monitor AFR activity. I will try to publish some data soon on this topic. I have been able to isolate the cause of all the surging at 3K and it isn't fuel management. I think it is spark timing! | ||

Davo still Davo.  | ||

Davo, That is some pretty deep stuff. I was expecting something on the line of making my turn signals into hazard lamps for blinking.. Well, I have left the wires alone for now as I dont know what snipping them will do to my warranty. |
