OK, I had 2 things done. 1. CA Canister 2. Charging Harness 1. I HAD to get the CA Canister. I just couldn't bear the gas fumes in the garage any longer. Plus I left a good pint on the ground at a gas station after filling up one day. That just pissed me off. CA can looks installed fine. They added a zip tie that doesn't belong there, but I won't complain. No fuel smell I am happy. 2. Buell said I needed this charging harness. Install looks good. They didn't follow the factory method of wiring with a CA can, but I like what they did so I will leave it. They had no issue sorting out my solenoid resistor and I think the tech enjoyed my American Sport Bike seat retention kit. Issue: I pulled into the driveway and voltage started dropping immediately. It seemed to level and stay constant around 12.3-12.4. The relay was going NUTS. Anyone else have experience with the charging harness care to comment? ac | ||

yep. the updated harness doesn't fix the dammage that has allready been done to the stator. see your dealer | ||
| Nillaice |
in the mean time you can read the other posts in this section of badweb, and save up for that GP shift kit that i know you're eye-balling | ||

I don't understand that statement. I have NEVER seen <13 volts before. Even riding into the dealer earlier this week. Would I be better off without the harness in the loop? Everything seemed fine then. ac | ||

I think the harness will allow the voltage to drop to keep the stator cool in low RPM situations. | ||
| Nillaice |
it's your ride, so it's your choice. reportedly; you can unplug the new harness and it will go back to pre-'upgrade' but i don't think that is the "FIX" for the underlying issue | ||

I've never seen my voltage drop since the harness or before. Never heard the relay make noise either. Sounds like something isn't right. Or maybe mine isn't right, who knows. | ||

I just don't understand why it seems so many people INSTANTLY have stator issues when the harness is installed. This seems like the system is working as designed. The relay is clicking like crazy. That means it is cutting power output I believe. I think THAT is why the voltage is dropping. I just don't understand how this system is supposed to work. If they let the battery drop to 12.3 just before shutoff, there will be a lot of people with hard starting. ac | ||

Bueller4ever, Have you ever looked at your relay with the bike running? I had the seat pulled while idling in my garage. I can feel/hear the relay clicking. I can easily check the dealers work. I will do that tomorrow. ac | ||

By dropping a leg of the stator output, it keeps the stator from generating as much heat. Read the letter that came to alert you to the harness. It's not a VOLTAGE fix. It's a HEAT fix. It's SUPPOSED to drop out some, if it's getting hot. The cluster doesn't read your BATTERY voltage, it reads your CHARGING SYSTEM voltage. And the ECM monitors battery voltage and will keep it in check, by balancing the heat cutout with required voltages. Now, there may be a case where the harness was installed *after* the damage was done to the stator...but in most cases this behavior is totally normal. Ride the bike. | ||

Ratbuell, Battery voltage and charging system voltage are the same thing. Voltage across a system does not vary. The stator puts out AC voltage, and is MUCH higher voltage than 12-14 so I can tell you the IC is NOT displaying the stator AC voltage. I understand what the harness does, this is why I am asking if it was REALLY designed to kill charging at idle. That seems like a lot of guys will wind up with dead batteries. I didn't have the guts to run the bike at idle until the battery was TOTALLY dead to see if the ECM would allow charging then. At 12.3 it was only 70% charge voltage. If this is normal, great. If not, today is going to suck as I am riding 300 miles. LOL ac | ||

I have not listened with the seat off. I will next time I ride. I've seen a low of 13.7 and a high of 14.3v. The instrument cluster shows the voltage at the battery, not sure how that can be different from charging voltage. If it only showed charging voltage, then it would read 0 with the motor off, key on. | ||
| Avc8130 |
Aww crap! This might be a LONG day. ac | ||
| Avc8130 |
I checked the install. Pin 21 on the ECM has continuity to the relay ground. The harness is installed properly. ac | ||

The way I understand it when there is a demand for charging the relay kicks and it will charge when at idle, and when the demand is not there it will kill a couple of legs of the stator, it makes sense that you would here the relay constantly working. | ||
| Avc8130 |
Well, my stator definitely works. I rode 280 miles today and voltage never dropped below 13.7 when moving. Stopped it would drop WAY down. It's almost like the bike doesn't charge at all at idle. I am just curious what the bottom threshold is before it kicks the charge back on. ac | ||
| Bueller4ever |
Have you lowered your idle? | ||
| Petereid |
Avc do you have a Erik Buell Racing EMC or stock? From what I have read the Erik Buell Racing one drops the RPM and won't charge the bike at idle. If the drop is only at idle you should be fine unless you spend most of your ride sitting still in traffic (which really sucks on a bike anyway) | ||
| Avc8130 |
Stock ECM is currently installed. I put the stock ECM in so the dealer wouldn't mess anything up when they reflashed as part of the install. ac | ||
| Ratbuell |
What flash is in your stock ECM? If your flash is out of date, you'll get ridiculous relay clicking because the ECM doesn't know what to do with that extra pin. And hopefully this won't start an ad nauseum flame thread...but system voltage (instantaneous) is *about* the same as battery voltage...but if you take amperage into account (what REALLY starts your bike) the V reading is pretty worthless. A reference, if you will; nothing more. Yes, the stator puts out AC and the system reads DC. And...? The harness is NOT designed to "kill" charging at idle. It IS designed to kill stator overheating. Regardless of RPM. Save the hardware, vary the software. I put over 100 miles on my CR today (post-harness) after I got off work. Not gentle miles. I saw everywhere from 12.7V up to 14.1V, depending on traffic, RPM (tried to keep it above 5k - it's more fun there anyway LOL), and temp (AT varied between 89 and 64 actual in the mountains). Current flash, harness operating properly. I saw 12.7 for about half a mile so I pulled off, hit Kill, sat for a second...and she fired right up. Riding (and restarting) with high beams on. | ||

I haven't checked the flash...but when I dropped it off it had 152 in it. My understanding is they reflash to 152 with the charging harness install. I 100% realize the purpose of the harness. My issue is that the bike is running off the battery at idle. I can picture it now: Come home and ride through town in the summer. Fans are spinning because it is hot. Hit a few lights on the way in. Pull into the driveway. Shut off the bike. Fans run for a minute and the fuel pump runs for 10. I see some people with dead batteries. Any idea where the ECM control for the relay resides in the ECM w/ Tunerpro? I am very curious to see how it works. I am hoping there is a minimum voltage where it will kick the stator back in. ac | ||
| Bueller4ever |
Is everyone seeing under 13 volts running their high beams? | ||
| Avc8130 |
I don't notice any difference based on what is running. I just notice based on idle or not. ac | ||

The ECM *does* have code that will turn the stator back on full if it hits a low threshold. Whether the threshold is a V level, or a period of time below a certain V, or what...I don't know. But it is there, and I'm sure the guys at Erik Buell Racing don't want the stator fix to kill batteries so they wouldn't have written it that way. And if you've ever ridden an XB, or a HD Big Twin, or a Sportster...you rode a bike that runs off the battery at idle. Typically they don't charge until at least 2200 rpm. Stop worrying. Go ride. If you have a problem it can be fixed...but my guess is, unless you had stator damage prior to the harness install, you're worrying too much and for no reason. The people who have dead batteries probably had stator damage prior to the update. My bike, with 1k miles on it now (I gotta ride that thing more often!), performs flawlessly with the update installed and the 152 flash. | ||
| Avc8130 |
Yeah, I am not worrying too much. I did 300 miles yesterday when I wasn't sure it would work. LOL ac | ||
| Bueller4ever |
I could not hear the relay clicking with the seat removed. I assume yours is easily heard over the exhaust? |
