I believe that it creates a new "Angle of the Dangle" | ||

I charged the battery up last night. It showed 12.81v this morning, drove it 25 miles to work measured again at work 12.76v. On the way home it lost power during acceleration a couple of times engine wise, I still had electronics lit up. Seems to have lost a little git up and go. Measured voltage again at home and it has dropped to 12.72. Before it was showing 14+v at idle now a mere 12.3v at idle. It is going to the dealer tomorrow. I do use the engine Kill switch then the key to turn off the bike, so keep guessing guys! Has anyone noticed a white glare to the paint? Looks like when a double pained window separates. I used black hawk cleaner and S-1000. | ||

Trw, does the voltage rise if you increase the throttle? | ||
| Trw |
yes, it would hit around 13v at 5500 rpm. give or take. | ||
| Trw |
Just checked it again. 13.9v at idle. Something has got to be loose and or shorting. The batt. cables are tight. Maybe I can get this figured out tonight. Fingers crossed. | ||
| Cataract2 |
Trw, did you check the neg bat connection around the rear shock? It was brought to my attention that that area could come loose. | ||
| Trw |
Just got done going over the bike. As far as I could tell nothing was loose under the seat or other wise. I can't break her down to parade rest though, at least not the day before she goes to the docs office. I will update when some definitive is found out. | ||
| Trw |
YAH!!! I get to pick up my bike tomorrow. No, it is not fixed! Has anyone had this battery draining problem rectified? Time to bust out the schematics, O-scope, and multi-meter, and get to work.  Anybody have any suggestions or want to swap info on fault isolation and symptoms? Oh, the tech at my dealer says it should have came up with an error code but mine didn't. Did your's? And what was it? | ||
| Bobup |
Trw In answer to your last post, yes, mine was resolved, as I have posted in this thread (thread that I started by the way). My ECM was sent to BMC and they replaced it. no problem since then. There have been other postings that supposedly BMC has a "flash" upgrade for the ECM...this may be the difference between my original ECM and the new one. bob | ||

The only time I had a battery problem was when the bike was new. I have had my fuel pump turn on after the bike was off. If the pump is running then the ecm is awake and drawing power as well. I thought about checking my bike with a Fluke meter set to min/max overnight. This will give you an idea if something comes on overnight causing the battery drain. If it does then you could start pulling fuses and check with min/max overnight to see if there is a change to pinpoint the problem. The first one I would check would be for the ecm. If the ecm is on it would not take long to drain that little battery. | ||

Wait for at least 20 minutes after you've shut the bike off. The fuel pump will cycle to keep 75 psi on the rail for that long. Specs, page 1-1 "E - Manual" Z | ||

Bob up: I should have read more closely? I have read this thread many times and this morning was the first time I caught your Follow up thread. Moving on... Did your bike throw an error code when it was draining the battery? How can I convey to my dealer that my ECM is the problem? Does anyone really know that the Flash update can resolve the issue? Does the flash code have a reference number or identification code to determine that it is the correct flash for me? | ||
| Zac4mac |
TRW - Dunno about the flash update. I have #154 built Nov6 with the original ECM, no flash. Also no electrical problems except when she was new(my bad habits), I flooded her and drained the battery twice trying to get it started. Mine hasn't been on a tender in over a month and starts every time. Z | ||

TRW, I am still on the stock ECM, with no flash either. On my bike, I know for sure if I turn the key off with the kill switch in the run position, if the bike is not running, it will kill my battery. I proved this last week by killing the engine with the kill switch, turning the kill switch back to run, and turning off the key. Battery was down to 6.5v in 3 days.  So I think I have solved my battery issue. This may not be true for everyone's bike, and turning the key off while NOT running with the kill switch in run position may show a different draw than just turning the key off with the engine running (didn't check this). Since this seems to only effect a few people, there may be some differences in bikes (which there should not be) or it may be related to some part that isn't working correctly, don't know.  Please let us know what you find in your analysis, more data would be better in this case.  Since killing the battery I have charged it back to full 12.83v. After checking it a couple times a day for the last 3 days, only .01v drop each day while not riding it, and a full 12.83v measured if I do ride. This is killing the engine with the kill switch, then key off immediately. | ||

Trw no codes thrown that I am aware of...I did not check...I just know that when my battery was totally flat after sitting for only 5 days, something is wrong and took it to the dealer. I had emailed my service Mgr a couple days prior to taking it in, so when I had dropped it off BMC already had a game plan in place. explain to your dealer what is going on and have them FIX IT... the kill switch position may be the difference, but the ECM controls how things work IMO. I read my XB manual, and it states to shut down the same way kill the engine and then turn off the ignition....BUT, it adds that you MUST turn off the ignition so that you don't DRAIN the battery this is from the online manual.... "Stopping The Engine: XB Models -------------------------------------------------- ------------------------------ Top of page See Engine Off/Run Switch: Buell Models. Push the upper part of the engine OFF/RUN switch to shut the engine OFF. See Ignition Key Switch: Lightning Models. Turn the ignition/headlamp key switch to the OFF position. IMPORTANT NOTE: If the engine should be stalled or stopped in any way, turn off the key switch at once to prevent battery discharge." HTH bob | ||

"the tech at my dealer says it should have come up with an error code but mine didn't." If all your tech knows to do is to check for an error code, then you might need to find another technician who is able to actually diagnose a problem on his own. | ||
| Trw |
My tech tested out the charging system and it checked out fine. Checked the stators, and voltage regulator which is what some had problems with I believe. I ain't trying to trash my dealer techs' and I hope it doesn't seem that way. After all they are working on a bike they don't a completed service manual for. It's new to everyone. However I am frustrated. The tech also stated that there is NO other flash than the one I already have. So that leads me to believe it ain't going to fix any problems. Being as I am still having issues. I'll post somethin when I got somethin! | ||
| Cataract2 |
Trw, have they swapped batteries for you yet? | ||
| Trw |
No, they load tested the battery and it was fine. I got the impression they want it to go dead again in hopes that it will come up with an error code that may shed some light on the issue. I will be checking batter voltage regularly. Also the 4200-4500rpm stumble, thing seems to be the bike choking out like to much fuel, It did it many times in second gear on my way home from th shop. Its as if I am given it to uch throttle, fuel injected bikes shouldn't do this should they? My Harley didn't. Also it was second gear this thing should jump and go not flood out and die. I will be calling the HD dealer first thing monday morning. (Message edited by TRW on April 27, 2008) | ||

Last week's experience: Wednesday morning -- dead. Hadn't ridden it since Saturday, mostly because of the weather.I had been into the left side scoop looking for a dropped air box rubber washer on Tuesday. Had some issues trying to get the bottom back screw to line-up, but eventually got it. Checked the battery, after work, to be at 5 volts and charged it back up. Go to see how it's doing; lights on, cycles through, engine lamp goes off and then back on. Code says: LT FAN SYS ERR. So back into the scoop to find the fan disconnected. Reconnected it and everything is good. So what drained the battery, inactivity or the system error? Guessing the system error / fan disconnect, but won't know unless it happens again. As of Friday, no word about the memory flash of the ECM, but it seems OK and I'll wait for further information to be disseminated. oh yeah, that washer is still missing... fortunately I had a spare. | ||

Trw sounds to me like your tech hasn't been in touch with BMC. BMC does know about the battery drainage....and they have a fix for it. | ||
| Cataract2 |
Bobup, what is the fix? I've heard nothing at this point. | ||
| Bobup |
read back a few postings...April 25th | ||

Ok, so does anyone have any solid info on this flash update? Has any bulletin been released on it? | ||

Has any bulletin been released on it? Yes. See your authorized Buell dealer. |
