Hello, Since I installed the HID kit from DDM Tunning, some issues appear. "System Voltage Error" appear in the display after a complete electrical shoot-down of instrument cluster and headlight for 1-2 seconds while driving, the engine didn't stop. After this 1-2 seconds instrument cluster and headlight, comes back and works perfectly. This issues seems, apparently, any patron of appearance. In 2 weeks this issue comes 4 times. And the last one came 2 times in a row, I mean shoot-down/online - 5/10 seconds, and again. May be the voltage regulator or maybe is the new HID kit? With the standard light H7 never had any problems related to "System Voltage Error" Thanks in advance P.d.: This is the threat with the tutorial http://www.badweatherbikers.com/buell/messages/290431/535426.html?1265000213 (Message edited by Ros on November 13, 2010) | ||

I was advised to stick with the 35W to avoid this specific possible issue. Not sure if it is for sure the cause but i havent heard of anyone having that problem using the 35W HID | ||

My 35w DDM kit has worked flawlessly. Had to do some wiring changes, but those were done for personal reasons. Only thing I can think of is maybe your battery is bad. HID's pull allot more current at start than regular bulbs, after they warm up they pull nearly the same current. Hence your total shut down and then everything comes back on. Unless your problem occurs after the initial warm up of the HID's | ||

My kit is 55w, and the error comes sometimes when the bikes is up and running for 5-10 minutes, never when just turn the ignition key and startup. I know the HID pull more juice from battery when it warms up, so this is the reason I never let the HID warmup if the engine is not running | ||

Mine has started to do that too. Same error/warning. Electrically mine is stock, and my battery voltage tests out @ 100% with-in spec. | ||

My battery seems to be operating at normal spechs, 14.2-14.5 volts on display. Some times I saw a peak of 15.2 volts, when the error comes, but maybe because it's just the moment the HID is warming up. But a seconds later, 30 maybe, drops to 14.2-14.5 | ||

? Silly question but are the battery terminals and connections clean? Seams small but allot of my electrical problems were solved there. Other than that maybe you should change the color of your bike. That will keep things cool. Haha kidding, that front wheel makes it look bad ass. | ||

tmchcrk jajaja yes it's a bad ass, and more will be with the clubmans installed!!  I'll check the battery conectors, but I think they are ok | ||
| Tmchcrk |
I'm sure they are. Oh yea clubmans maybe bar end mirrors. It'll be hard to keep the ladies off it.  | ||

At around 9000 miles, my 09 1125R started getting System Voltage errors on the last 3 rides. The first two times it happened once after starting out, but went away after shutting down and starting up again. However on the latest ride last Saturday, it happened persistently, recurring immediately after taking off in first gear. Figuring it wouldn't resolve itself by keeping on riding, I went home in an effort to find a cause. With a voltmeter on the battery, it showed a nominal 12.8 VDC before starting, approx 13.5 to 14.5 at idle without the System Voltage on the IC, but when the error showed just by revving in neutral, it would read 18 to 19 VDC. And the error message was happening every time just by revving in neutral now. It seemed like it might be a Voltage Regulator problem. Remembering VR grounding problems with some earlier tubers, I thought I'd check to see if there might be a loose ground in the battery or regulator wires/cables. There was some slight corrosion on the negative battery terminal but the cable contact surfaces seemed clean. The other ground cable connections were clean too, so no help there. I removed the VR to check the connector contacts and all seemed clean and like new condition. Wondering if there might be a grounding problem with the VR, I noticed that the VR's metal case was isolated to all its wires. Without the Electrical Service manual I don't know if this is normal. One thing interesting is the word DUCATI cast into the metal case. Could this VR be cross-referenced to certain Duc models? This is the first problem I've had with it and it's unrideable. So it's back together and a service call is placed with the dealer. I'm hoping the mfr's 2 year warranty covers the cost. | ||

Wow really interesting diagnostics Sparky, but you have installed the HID or this issue is with standard H7 bulb? Because for me, this issue started since installed the HID. So the HID kit is bad or battery cannot afford the electrical demands of HID or the VR is failing. As you next week It's time to visit the dealer to 20k km service, and ask about this issue. When it's done I say something here. (Message edited by Ros on November 16, 2010) | ||

This is the best I can do, Spark.    Not really a true schematic, but will have to suffice as that's all I can find in the manual. (Message edited by jeepinbueller on November 16, 2010) | ||

"Wondering if there might be a grounding problem with the VR, I noticed that the VR's metal case was isolated to all its wires." An Anony posted a week or so back that the regulator case was electrically isolated, so that would fit. "word DUCATI cast into the metal case." Made by Ducati Energia, not the motorcycle guys... Good stuff, keep at it. Z | ||

Thanks, Jeep. The middle diagram clearly shows the starter with an earth ground to its case whereas the VR does not. The bottom diagram shows one ground wire to the VR through the wire harness. OK, good so far. Regarding the battery ground circuit, I physically traced the big cable from the batt post to the engine case. But I did not trace the black ground wire at the VR connector back through the wire harness. I'm curious to find out if that VR wire is the other smaller gauge wire connected at the batt negative post. | ||

My issue is much the same. Had system voltage appear, still ran it and went to shops and now she won't even start. You turn ignition, cluster lights up and press the ignition and all you hear is starter relay clicking. Ive charged battery for 24hrs and did a load test. Tested perfect. I I've checked all the relays and even changed the harness relays. Im thinking maybe a loose wire to starter motor but can't seem to get to it. Also I'm blowing headlight fuses. I thinki have 2 faults. Im in Townsville australia and doesn't seem to be buell specialists here. If anyone can shed any more light on what to look for next. Im thinking VR but im expecting it to be more than 1 part needed. I've only had it for 3days. |
