    Charging monitoring problem

    Hello everyone, I have posted about my problem on k-bikes and i-bmw but thought that I would post here and see what feedback I get.

    I ride a 2006 K1200GT. On a ride to Arkansas in August the red general warning light came on along with the battery indicator which indicates that the battery is not being charged. However, checks that we made indicated that the battery was charging fine. Additionally, my radar detector reads the battery voltage and the voltage has been as it should be. I have now ridden 7000 miles with the indicator lite so I am certain that the battery is charging as it should be and that what I have is a monitoring problem.

    The issue now is that no one can tell me with certainty how the electrical system works and what the most likely cause or causes may be. Is there anyone on the forum that has intimate knowledge of how the bike's charging system works and can explain it?

    I appreciate any experts that are willing to help me out. Thanks and have a great evening.

    If there is any information that you feel I have omitted please ask and I will add it. Thanks again.

    I would be interested in what brand/type of battery you have. I want one of those 7,000 mile batteries. The warning can't be wrong can it.

    I think a "reset" of some variety is needed but I don't know what for sure.

    Haha. I have an Odyssey battery which has served me well so far. The battery is charging fine. I have been to Sipapu NM, Colorado, through Ark, Miss and Tenn with no problems. How's everything out west?

    Dry, blue sky, 75 degree day today. I painted the overhead water tank. Voni had to go to town to get more RED paint.

    What did you check? What did you measure?

    What did it display at cruise RPM?

    We check at the battery with the engine idling. It is around 14-14.4 vdc. Radar detector reads the same at idle.

    I can't tell you what it reads at cruise RPM as the voltage display is very small.

    That is fine as long as it does not increase with RPM.
