so my 09 1125R has been throwing the low voltage light all the time. i dropped it off at my dealer and they have no answer for me. get it back home and swap batteries with a firebolt just to see if that will fix/help ... D'OH! the terminals are opposite between the batteries. cycle the key and nothing... pulled it off and assess the dammage. blew the batt and fuel pump fuse. replaced those, ant it'll crank, but not start. swapped out relays, still crank, but no start. WHAT ELSE DID I FRY? the service manual (99491-09Y) isn't giving me the answer. i do keep it on a battery tenderizer. i have had the charging system recall done, the low voltage situation is being investigated by the dealer. i'm just trying to get it to start again. alls i have done electrically speaking is: HID lights, XBLights LED tail light, and heated grips, and lo-jack installed. | ||

Once you have swapped the batteries and confirmed that is not the problem, check the voltage regulator. Also, just to rule it out, unplug your hid's and led tail light. My 09 has a regular bulb tailight, and the 09's are set up for a bulb not an led, that could be messing with the electrical system. Once you unplug some of that stuff i think it will start, i think you may have too much stuff plugged into the bike. | ||

CORRECTION; i have replaced the OEM headlights with HIDs (which draw less current than than incandescent bulbs) and replaced the OEM tail light with an LED XBLights (LED's also draw less current than the incandescent bulbs) i'd check the voltage regulator, but doesn't the bike have to be running for it to produce voltage for it to regulate? when the bike was running, the voltage would stay around 13, then it would drop to 12.5ish around town, then at idle it keeps going to down to 11, then it cuts out | ||
| Dktechguy112 |
i understand you have replaced the oem bulbs with hids, my point is that some poeple have reported hid's cutting out at start up, so they must put some strain on the system. and since you are having an electrical problem i would remove the addons and see if that fixes the problem. One member posted up that installing a little led running light caused his bike not to crank. I'm not saying fully remove your hids, just unlplug them, the heated grips, and the tail light and see if that fixes your problem. As far as checking the voltage regulator, i'm not sure how to do that, i haven't looked at it on the 1125, i don't know if you need a special tool from harley or if a multimeter could test it. | ||

Do i understand you correctly...that you installed another battery, which had the terminals reversed,and then you attempted to start the 1125 and then discovered it was wrong (battery) so you swapped it back with the original battery and then you replaced several fuses but it still won't start,do I have the senerio correct? | ||
| Keef |
your original problem was a melted stator...by the way.I know because mine melted, mine is being installed,all the dealer is waiting on is the gasket,as I preordered the stator a month ago as soon as i started having problems i just forgot to order the gasket which is not on a backorder status and the dealer will have it Tuesday so I imagine I will get it back Tusday nite.. | ||

that's right, keef i checked the codes now it shows; P0629 FUEL PMP SYS ERR P0628 FUEL PMP SYS ERR P0087 FUEL PR SYS ERR 61005 LOW FUEL SYS ERR and the same P0562 LOW BATT VOLTAGE as before i'm guessing that the fuel pump is fried due to applying reverse polarity. but i need to get the 'electrical' service manual which is different from the regular service manual.  any body allready got one so i can verify or further troubleshoot this before i pay for the service technician to do it for me? | ||

I am thinking the fuse for the pump is bad I doubt the pump fried, also did you try checking the idle if its a little low you might have to raise it a bit to get the charging light off | ||
| Nillaice |
the fuel pump fuse was fried, i replaced it with another 15 to no avail. then a 20 amp just for shits and giggles. still no dice. it's loaded and strapped down in the back of the truck. | ||
| Dktechguy112 |
i just checked my electrical diagnostics manual: p0628-fuel pump control circuit low p0629-fuel pump control circuit high p0087-bad fuel pump p0562-battery voltage low, only trips if the voltage falls below 9.6 volts. usually tripped by a loose wire or the ecm not detecting a voltage rise as the rpm rises. | ||

Ok, pulled out my electrical manual, and it says:"If the fuel pump is faulty, DTC P0087 sets," Did a little further reading here, technically, ya need something called a "Breakout Box", some sort of diagnostic meter. Anyway, there is also the possibility that your ECM my bad as well. Sorry for the bad news buddy. | ||
| Jelomadnes |
Someone beat me to it. | ||
| Keef |
the bad news is you probably fried some sensors and maybe the ecm and cluster... processors do not like reverse polarity and then you turned on the key bad bad news sorry maybe you got lucky and only ruined a few sensors but fuses can only save so much, once the smoke gets out of the wires things go pobar quickly....  | ||
| Nillaice |
i was afraid of that  thanks for the electrical diagnostics manual info, and verification guys. knowing is half the battle. maybe the dealer can order me some more 'magic smoke' and put it back in the ecm  | ||
| Nillaice |
i wonder if i can get a loaner bike for the mean while? anybody know the key words or tricky phrase you gotta say or is it just "pretty please, with sugar on top"  | ||

It'll depend on your dealer.. Out of interest how honest are you planning on being with them about how this happened? It'd be nice to be up front with them about what happened, but I suspect that'd void your warranty. You're going to have to be a VERY nice man to them when you get there...  | ||

Matt,my guess would be the fuel pump+ECM.I would use the Erik Buell Racing ECM[cheaper].I ran into the same problem. | ||
| Nillaice |
dealer is booked 'til next week. in the mean time i'm buying some new relays (they are the same for XB's, and i figure they'll be good for spares/future troubleshooting) and i'm looking to borrow/buy a stock ECM.  http://www.badweatherbikers.com/buell/messages/21/ 562935.html?1273522750 i had the chance to buy a break-out-box over a year ago, and am kicking my self for letting it pass. | ||
| Keef |
Dude spend 250.00 for one from erik buell racing you won't regret it ... | ||
| Nillaice |
i don't know how much its gonna cost me to get it back up and running so i can enjoy that pump gas ecm, so i'll hold off on splurging just yet. so, ... any body got an ECM they aren't using? i'll keep it or send it back to ya and buy that E B R ecm if it is the fix. | ||

Try for warranty, what they dont know wont hurt them. I find it interesting it should of blown the main fuse & thats it, why have a fuse if it destroys all the things it is there to protect. Never ever seen the problem B4 on all the rice burners I have worked on over the years??? | ||
| Nillaice |
i still got a fist full of days to twiddle my thumbs and leisurely peruse thru the service manual.  i know Priority mail can get a teeny, tiny 'lil 'ol ECM cross-country in like 2 days, and then i maybe could get it fired up and back on the road ... ... as long as i keep the rpms up to maintain voltage  | ||

"I find it interesting it should of blown the main fuse & thats it, why have a fuse if it destroys all the things it is there to protect. Never ever seen the problem B4 on all the rice burners I have worked on over the years???" The electrical system on motorcycles uses dc current, which means current is only designed to flow one direction, when he hooked the terminals up backwards current flowed in the other direction. | ||

Well if you had the ebr ecm you could,if everything else is ok,ride the bike and then when you go to the dealer ride it there .While there swap the ebr ecm out with the factory one and push it in the door to them.Let them figure out the problem why the ecm won't program or work and let them put you a new one on thinking they are the cause and you should swear it worked before you took it to them...an idea... | ||
| Jason13 |
you should just punch the guy in the face for doing it wrong. i mean who is that smart to hook it up back works stupid.  | ||
| Nillaice |
keef, you are mischievous | ||
| Nillaice |
jason, the real question is who would let such a questionable individual come anywhere close to their bike with a wrench in hand. | ||
| Jason13 |
hahahaha the kind that get drunk together then blow sh!t up..... good times  | ||
| Jason13 |
plus this person you speak of did he even have a wrench???? or was he ninja like  | ||
| Nillaice |
... bueller? | ||
| Nillaice |
holding out for the word back from the stealership. fingers crossed. hoping for the best but preparing for the worst ... anybody wanna lend a hand? | ||
| Froggy |
Nillaice, what was the outcome of this? Another member did the same thing with his bike http://www.badweatherbikers.com/buell/messages/290 431/722233.html?1380137023 |
