Charging Issue??

I am hopeful that there are some folks of the forum who are pretty good motorcycle mechanics and are willing to share a bit of their experience and wisdom to help point me in the correct direction for next steps.



I have a 2006 K1200GT and am currently in Eureka Springs, Arkansas to enjoy the beautiful motorcycle roads Arkansas has to offer. Yesterday morning when we left Mena, Arkansas we rode about 20 miles and my general warning light came on red. Also, the battery symbol came on. I pulled over, got my manual out and learned that this was an indication of a charging issue. While pondering what to do I remembered that my radar detector reads the charging voltage and after starting the bike it read 14.2. We had stopped on the side of the highway and decided to move to a safe local to investigate further.



After getting to a rest stop we removed the batter cover and checked the voltage to the battery with engine running. It read 14.2 V. I called a BMW dealer and explained the symptoms to them and they said that I was okay and it was likely a monitoring issue and that I needed to bring the bike in to have it analyzed. I elected to continue on the ride and rode 240 miles with the light on but with no starting issues or any indication that the battery was not getting a sufficient charge other than the warning indications. I am also wondering if it is possible for the charge to be the proper voltage but for the charging current to be less than what is required for a proper charge.



What should be my next step. I am supposed to ride from Dallas to Sipapu, NM next week for the Bavarian Mountain Weekend but I don't want to go if I am risking getting stranded in west Texas in the middle of no where. If I have neglected to list any info that might assist please let me know.



I apologize for the lengthy post and thank you in advance for any advice offered.

Quick stop at a local BMW dealer to see if any fault codes show up on their diagnostic computer? Many shops will welcome a drop in (Big Sky BMW took me immediately when out on a tour with a clutch slave problem), some might not.

I would definitely get to a BMW dealer for a diagnostic as soon as possible but it could be that your battery is starting to fail and this is causing the CANBUS system to indicate a charging fault. Until you get it checked, don't be surprised if the battery simply dies without warning when you go to start the engine. Also, don't be surprised at the cost of the replacement battery. Many on this site switch to an aftermarket battery. Do a search on "battery" in this forum.

Good luck and let us know what happens.

If you're looking for a new battery, you may also want to do a search on "Odyssey". (Or PC680MJ or PC680.)

Definitely sounds like your battery is just about done. i got the same symptoms when my 2006KGT was 3 years old.. Get an Odyssey..
Currently my 2009KGT is a year and a half old and i get a low battery flashing when I do a start after the bike is warmed up and shut down. i have to goose the engine to get the light out. I have the Odyssey in the garage to be hooked up in the next few days.
It can't hurt to try a new battery as you are going to need one soon anyway. This may cure the problem or it will not. then you need to see the dealer..

Well, the general concensus seems to be that it is the batter. I replaced the original battery last winter with a Odyssey PC680MJ. Is it possible that it has failed so quickly?

I suppose it is possible, but it isn't likely. Odyssey batteries have a reputation for lasting many years, far beyond the stock BMW battery. I have friends who have been using their Odyssey batteries for several years without issue. I have had mine for about a year with no issues or problems (bought in late June 2009, sat on shelf, installed in early October 2009).

Well I am back from Arkansas after riding an a twisty curvy 850 miles with the charging current general warning light on. The bike is obviously charging as thought or it would have died long ago during the trip.

Went to a friends house yesterday afternoon and swapped the battery out for his and still have the same fault. Left the power off for about 5 minutes to see if it cleared the fault but the fault remained. I am assuming that it has to be some type of monitoring issue. I am not working to locate someone with a GS-911 that can read any fault codes for me. Failing that I either have to go to a dealer or get a GS-911 myself.

Still want to hear any thoughts on what the issue may be. Thanks

A friend came by and hooked up his GS-911 to my bike to see if there were any faults that would cause my problem. The bike has no faults indicated and all of the real time data was fine.

What to do next?
