I got home from a road trip (12 days, 2k mi.), last week. The Uly performed great for the whole trip. Except, about a dozen times, when it died (while riding), for just a second, then restarted, then the check engine light would flash on for a moment and then off. After this sequence every thing would be fine (until it would happen again - about a dozen times in 2k mi.) This happened under a variety of conditions, from gravel roads, to smooth, straight, flat interstate. Temperatures were mild (60's to 80's). Any ideas, anyone else experience these symptoms. | ||

I have the exact same thing going on..... Dealer even checked for codes and nothing registered.... I'm tuned in...... | ||

Usually this is from the ECM connector issue. | ||

or maybe the BAS, when it's bad it will happen with out reason, like you said in different conditions. | ||

Bike gets hot from extended ride, seat pan flexes more due to heat, puts pressure on ECM connector, intermittent running problems. ECM in stock location? Are you a big guy? | ||

The cracked ECM connector issue is much more common on 08-up bikes; his is an 06. Still, it's worth checking. It does sound like possible BAS, but I thought the BAS would kill the engine until the kill switch or starter switch had been cycled off/on. | ||

P.D. I think the 'reduced' seat in combination with high temperatures in the ambient, has more influence. | ||

Mine is an 06 with broken ECM-Soldering-points. Roger that; the '06 is almost a given for ECM failure due to cracked solder joints on the PCB. Arry, You should consider getting a replacement ECM or repairing the one you have. Then doing one of the relocation mods. | ||

Thanks for the ideas/theories. My 07 had very low miles, when I bought it two years ago. At that time i added a support to hold the seat off the ECM (instead of relocating). I'm a lighter rider, but it still may be a seat/ECM issue. The BAS is still in the stock position, so it is a suspect, but I didn't have to cycle the key or kill switch (it always restarted on its own). I'll probably continue riding, as the problem is very intermittent and goes right away. I am wondering if the bikes that have had ECM or BAS problems matched the symptoms in my first posting? | ||

4_pete_sake, How long has your bike been doing this, how often, are you continuing to ride? | ||

"I'll probably continue riding, as the problem is very intermittent and goes right away". Sorry but that is a VERY bad idea. Sooner or later it will go bad "big time" and you will break down altogether. If the bike has a fault/problem it is best to fix it. "I have the exact same thing going on..... Dealer even checked for codes and nothing registered.... I'm tuned in......". Many a problem does not show up in the history which is why a lot of them are such a problem finding. I have had many faults and NONE were in the history or CEL. Check ALL the wires for damage but mainly the ones that go over the rear cylinder head. This was my problem and seems to be a known fault. You can check the BAS by turning it off. It could, of course, still be the ECM but do the simple stuff first. Good luck. | ||

flash out the stored codes. When mine acted similar ('06), but without the stalling, I found the ECM Failure code was stored. It was my ECM, even though bike still ran OK. Got an EBR ECM. I also added another support post at the ECM bolt that did not have one. I have the stock '06 (tall) seat, and am not a heavy guy (175lbs). If you have '07, I would think the BAS would have already been relocated to the tail section. Checking BAS would be another good move for your trouble. | ||

My '06 never presented a problem with the ECM couplers touching the seat or female terminals, nested in the gray and black couplers. But the PCB was cracked similar to the ECM in this thread: http://www.badweatherbikers.com/buell/messages/142 838/673617.html?1333122196 This is most likely what is wrong with your ECM. | ||

As I said check all the other stuff first. That is because it will be cheap/free. A new ECM is not cheap to buy if you do not need one or be able to afford it. I was not 100% sure it was my problem but bought one anyway as I had thought before of having one as a spare anyway. In the future most parts of this bike can be replaced or fixed with other common bike/car parts or reworked/rebuilt. The ECM, however, is another matter as it is Buell/HD specific part. And although you could fix a 06 ECM the later ECMs have twice the number of pins and would be a LOT harder to fix if at all. As a side point. I have noted in the past that specific bike parts tend to become very costly, over time, on older bikes IE Electronics and plastics. Something to be aware of for the future. | ||

I hate to admit it, but I don't have a laptop/cable/spyware to monitor/alter the ECM. So, today I checked for stored codes by jumpering pins to get flashing check engine light (as per service manual), apparently no codes stored (quick flashes, "intermissions" only). My riding season is about over, so I'll be checking the bike over during the off season (looking for chafed wires or loose connections, as suggested). I don't have a convenient way too turn off the BAS, but I might get the recall/relocate done. I'd like to keep the stock BAS, but doubt that the service dept would let me keep the recalled part. This issue has only reoccurred once in the last 500 miles. | ||

So when the bike goes back on, the engine light comes on as if you just poked the kill switch. Something is interrupting power to your computer. Perhaps something as dumb as a slightly loose battery terminal. Perhaps something sneaky like a fatigued wire in the harness. Time to start wiggling stuff while it's idling. | ||

Just recently with my Uly, I had my turn signal flasher lose its ground - wiring issue, I ran a new ground. all good again. Loretta, my 08 1125R is still at the shop. Wiring breaks(3 of 4 wires) at switch. Running with twisted wires and black tape. Still need to solder/shrinkwrap. An issue endemic to Buells seems to be wiring. I had a Lotus once with Lucas electrics..deja vu. Z | ||

Natexlh1000, It is like I "just poked the kill switch" (or toggled it off, then on). So, that is a good angle for me to look at this issue, as I'm looking over the wiring diagrams. Thanks |
