I was looking at the spec's for the 2009 1125R and noticed the following regarding the charging system vs the 2008: 2009 37-amp, permanent magnet, three-phase, solid-state regulator (500W@7000 RPM, 500W peak) 2008 32-amp, permanent magnet, three-phase, solid-state alternator with solid-state regulator (432W @ 7000 rpm, 432W peak) Not really sure what that means in the real world other than the 2009 is generating more watts. | ||

I bet Bagger Mike will be happy to hear about this. | ||

Yeah 68 watts will make all the difference in the world? The 5 amp may help. I really think that some of the issues were s-ware related and some were rider related. Some small % were system capacity. Don't get me wrong, I am a wh0re for more power, even in the charging system. | ||

Jim: I run with my hi and low beams on and have now problem. I feel it's the rpm's and many other factors. I have had the reflash but, I had no issues B4. I'm not running out to replace mine but, I would not turn down an offer. Maybe because I use a "good" % of my generating capacity, but not too much, is why I don't have an issue. Just a guess. But a guess based on 8400 miles. How many miles on your 1125r? | ||

Hey Ccryder, Mine was dead after having been at full state of charge as of the last ride I was on, then, 5 days later, went back out to the garage to start it, and it was deader than a doornail! (not sure exactly how dead a doornail gets, but, you get the idea)  Anyway, my issue is more about the ability of the battery to stay fully charged up for a REASONABLE period of time once the bike is shut down. I've never had a bike with a properly operating system and good battery behave this way. What are your thoughts on this? Thanx, Tracy | ||

Tracy: I agree 200% that your battery should stay charged more than 5 days. As you say it was at a "full state of charge". IMHO you don't really have a charging system issue but, you have a battery drain issue. If you have had the re-flash done then you have narrowed the potential causes. One easy way to figure if it is the battery not holding a charge or something on the bike draining the battery is to disconnect the battery. Check the voltage with a good DVM and wait a few days. If it drops voltage, in 2-5 days, below the 12.00 volt range (from 12.7 or more) then...... you probably have a bad battery. After that you can look at other potential causes. Step by step is the easiest way (I have found) to trouble shoot most problems. Later | ||

No problems with Loretta's electrics. Got home from Homecoming to a dead Tender Jr. Not the greatest customer service from Deltran, still without one. Fans are running a lot these days with highs near 100. At least I'm not running the heated grips... I've had the battery dead only once, the day after re-flash. 11,705 miles. Z | ||

My battery also died several times before the re-flash, once the day after the re-flash and then never again. It sure would be nice to have a firmware version menu within diagnostic mode so that we could tell what version somebody is on quickly and easily to help troubleshoot things like this. | ||

The parasitic draw that my bike had was very hard to find. It would only have a draw sometimes, and it would kill the battery in about 24hours. It would click but not crank. I caught it one time with my Battery Bug and tested it and found the cluster had a 178mA draw. After the new cluster was put in no more dead battery. I don't use a tender and the battery voltage after sitting overnight is now 12.6 to 12.8 volts. Sounds like it may be a parasitic draw and not a charging system problem. | ||

Hey Gang, All good inputs! I'm not sure what's causing it, and would have to agree with all of your points on this one. It may well be that there's a drain on the battery that far exceeds powering the clock memory, etc. I did probe the charging system with it up and running, (mentioned in another thread) and the results showed that as I progressively rolled the throttle back from closed, the juice wasn't (sufficiently) going back into the battery until well above 3000 RPM. Yes, it was going in, but, not enough to maintain the battery in my estimation. On another note, I have basically chosen NOT to reflash as of yet, based mainly upon all the inputs of guys who have had it done so far. It seems to be a really mixed bag of results to say the least! I'm concerned about making things worse at this point, so, I've adopted a wait and see philosophy. I'm hopeful that the new reflash coming out will be a substantial fix to several of my issues with this bike, and, allow me to take care of most of it in one swift shot! The good riding season here is not very long as it is, so, I'm trying to preserve what I can of it. Take care, Tracy | ||

Tracy: The majority of the charging systems on the M/C require more than 3,000 rpm to reach peak output. The 09' system is spec'd at 7,000rpm for the 500 watts. You will need to spin your Helicon engine over 3,000 to keep up with the normal drain just to keep the engine running. My daily commute is 55 miles each way. Two lane country road with speed limits of 35-55mph. I usually cruise in the 4,000-5,000 rpm range. Guess what? I don't have any charging issues. Many times I have checked my battery state of charge when I get home and I usually show 12.6-12.8v. I'm not running out to replace mine but, I would not turn down an offer. Maybe because I use a "good" % of my generating capacity, but not too much, is why I don't have an issue. Just a guess. But a guess based on 8400 miles. Later | ||

Hey Striperx3, I totally agree! And for the record, I don't normally "hover" at/below 3K RPM! I live out in the country with mostly open 50-60 mph roads, and so I do very little in-town scooting. I actually try to avoid in-town riding whenever possible due to the classic stumble between 3500-4000 RPM. Mine is pretty annoying! I'm hopeful the new and improved reflash will be here soon. I saw on another thread that someone stated "in the fall"??? I just have to work with it until then..... As for the battery, I'll continue to keep it plugged in when not in use. It's my insurance policy!  Stay safe, Tracy | ||

Just keep the revs up and the rubber down. |
