20' S1000XR not charging

[coachz]

I've got a 2020 S1000XR that left me stranded the other day. Once I got the bike jumped and running I see that it is not charging. Did the obvious of just confirming not a bad battery by replacing that and still no charge. I'm pretty familiar with the bad stator program having owned an F800 and just recently having split the engine and helped a friend replace the stator on her 1200GS.

My question is usually when you have a charging failure should you get the big red triangle of death on the TFT? I got no warnings what so ever other then trying to start the bike after my third stop of running errands the bike was down at 9v and then just fully dead.

Any input is appreciated. I'll be taking on metering out the voltage regulator and stator hopefully tonight to see where the failure lies.

Thanks!

I presume you have a lithium battery? Try searching this forum area using the Search link at the top right of the page. Searching the term "charging" and identify This Forum specifically. I saw lots of posts about the lithium battery...might help.

IF this is a lithium battery...

1. Many lithium batteries have a protection circuit that shuts them down if voltage drops below a certain limit, which can damage them beyond recovery. If so, it may take a dedicated lithium charger to "wake it" back up and charge.

2. Jumping a lithium battery can sometimes damage it. They are designed to charge slowly; jumping dumps lots of current into the battery at once. Check to see if there is any swelling, if so, the battery is damaged, get it out of the bike and away from anything combustible.

I guess I would first put a meter on the battery and watch the voltage on starting. Below around 9.2 volts, the bike wonders what you are trying to do.
The question on the lithium battery is a good one. Charging lithium and the related charging (instructions) I find confusing. I also find charging through the can-bus port as something I can skip.
If you are storing your bike in a cold location, some of these new style batteries have temperature considerations.
Let us know how you make out.

Does the My Vehicle screen on the TFT show 14.2 while riding?

FWIW, I've got 3 EarthX lithium batteries in 3 different bikes, one is now 8 years old. Charging/maintaining is no different than a lead acid battery, you just need an appropriate charger/maintainer. The "de-sulfite" cycle on a lead acid charger will kill a lithium battery.

Here in the AZ heat, lead acid batteries die regularly in 3-4 years, car or bike, many sooner than that. I've had them die at 13 months, and nothing has ever lasted more than 4 years. The first EarthX was my "experiment" and I'd never go back. A quality product, great customer service.

Bike stators do occasionally go bad. If the engine is standard UJM 4 cylinder design it shouldn’t be hard to replace, and I see eBay has stator/rectifier combo kits for a 1000 XR for around $130.

Battery is a lithium, bike came with the M lithium and I put in an antigravity just to check. New battery is known good and only trickle charge with a lithium specific charger.

No charge is not coming up when the bike is started.

Went through and metered out the stator and it is in fact toast.

I guess the thing that really puzzles me is the lack of any warnings at all on the TFT that it's not charging. Had I been riding down the highway at some point the bike would just have quit due to low voltage which is a bit spooky. I've got an extended warranty on it so will talk to whichever dealer is close down here.


Anyone have thoughts good or bad on the Miami vs Fort Lauderdale dealers?

That is precisely the same behavior exhibited by Voni's F800S and my G310GS when they were afflicted with stator failure.

Very weird to me. My friend's 1200gs that ate a stator did the Red triangle of doom. Very very odd to me that this, or any of the modern bikes really wouldn't. The bike knows the voltage obviously and if it's running and not charging there is clearly an issue so........ WTF. This bike has been a bit of a pain and unlike my several previous BMW bikes.

I was one of the lucky ones with my 16' f800 and did 25k miles lots off it WAY off the beaten path and had zero issues. None with the 850, 1200R, 1200RT, 1250RT, or the 1250R. Even had a first gen 310R that was flawless save for the subframe recall. Oh well can't win them all I guess.

Would a GS911 provide any clues?

Haven't plugged the bike in yet but given no warnings on the dash for a very clear cut problem I assumed (dangerous I know!) that there wouldn't be any history there. I'm traveling until the end of the week but will have a look Friday or Sat. when I get back to the bike. GS911 is usually my go to but yeah

 

[coachz]

Finally plugged in the gs911, shows a low voltage light pinged once but ten miles from where it stand now on the ODO so that would have been after the bike died and rode it back to where it sits now. One single instance and not still present even idling and again not charging. puzzled is an understatement

Not sure what that statement means.

What is the charging rate showing on the TFT while riding?

When starting and riding the bike with this failure present the bike never threw a code or an alert on the TFT. No "charge" was present at all so the voltage shown when it first made itself known was 9.3v and non operational. Charged the battery up to full and rode it to our base down here in FL and then topped battery back up to full for the ride to the dealer to drop it off. 25min ride I lost .4V but still over 12v given its a lithium.


I'm just puzzled that as soon as the voltage is under 12v while riding that the ECU wouldn't throw up a warning on the TFT saying hey we can see the engine is running but battery voltage is dropping ergo there is a charge failure and FY the bike is gonna quit!!

The local dealer here in FL replaced the stator and mag wheel under my extended warranty and I've only ridden it back "home" for the moment. Hoping to do a long ride on XMAS day to kill some time. Overall I'm really not loving the XR platform as of yet but we shall see. It's been far and away the most problematic bike I've ever owned. I may have just chosen the wrong bike for big miles trips I like to do. Missing my two RTs currently.....

 

[coachz]

I think I'm annoyed enough about this whole thing I may go for a ride and collect some data using both my GS911 and a high end Fluke meter to record voltage as well as amp draw vs revs across the range using just the oem as well as the lights and acessories I've added to get a baseline for this fresh stator.

Intersting that Wes just had an article in the MOA mag about oil and stator life. I'm a nut about pool changes and send out samples at each change on my bikes but this one being new to me I do not have a history like my prior bikes.

I assume you asked the dealer the same "why" questions you've posed here. And the answers were...????
