    2007 R12R instrument cluster anomaly

    H's 07 roadster at 104K has a new option...a warm weather activated dash display

    She said it happened last year during a cold spell but didn't seem to repeat until a recent drop in temps last week brought it back.
    Have had other roadsters, and a GS of this vintage have a failing ignition switch module...this presents differently as the bike will run.
    Turn key on, no display, but bike starts and all other electrical functions work. After a warm up during day, the dash comes alive.She used her GPS as a speedo last week until I said I wasn't going to be happy if it dies on her commute and ride something else. Mostly, didn't think it was safe to ride with no rider info and a roadside rescue by me that wasn't really necessary possible.

    I scanned for codes when air temp was below 45F when blank and it says no communication from unit. I used a heat gun and warmed dash for a few minutes from a safe distance and on it came. Repeated a few times letting unit cool with same results over a two day period.
    Tried warming just switch module from below with no positive results a few times just to take that off the table. I reset the clock each time I got the display working, but each time it locked the last setting as the next time it comes on is that setting, not current time.

    Seems the cluster is failing and the lovely thing is it is almost a $1200 piece of electronics. Found a few used half price units, but always cautious on pulling trigger on like items. It could go another 50K or 500 miles.
    She shook her head and it got pushed into the let's wait row for now.
    I had a few F800GS's here with a visually same dash, but the fiche says not, so it is model specific. Searched for similar failures on other sites and no luck.Most are switch failures.

    Strange indeed. Thank goodness you live where cool weather is fairly limited.

    First thing that comes to my mind is that the cool temperatures are affecting an electrical connector that provides power to the instrument cluster. Perhaps a pin or pin is barely making contact and when cold it shrinks just enough to break the connection. Id check to see if I could identify possible suspects on a wiring diagram and then locate the suspect connector(s) to see if it is properly seated, and apply heat to it when the dash is inop. A chemical hand warmer could be used to apply the heat safely and in a pinpoint manner.

    I have cleaned the units connector and socket and plugged/unplugged a few times. Opening the case and taking a peek may be next. I do have a damaged one from another bike to play with first as the case is already broken.
    A smaller heat source other than my heat gun is a good plan as well. I may be putting off the inevitable, but can't hurt.

    I am waiting for the advice of get her a new(er) bike but that is on her, she has sat on a few Wethead GS's and a R lately
    Hard to believe the original Hexheads are over ten years old now...makes me feel older too.

    Pulled what was left of rear housing from the damaged unit I had. Way beyond my paygrade as all the components are micro minnie.
    The cover has screws,mostly for bezel face, but also some one time plastic post/socket connectors that will not seperate from the cover w/out damage. I will leave the one on H's bike alone and spend some money to replace it. $1200 hard drive

    I would try the speedo repair places like North Hollywood. Most of the work they do now is on electronic instruments. They know this stuff.

    What a great idea Lee. You sould post that on H's facebook page, or even better yet, email it to her.

    I knew I could count on y'all for a solid solution

    She's thought about it, but I'm not saying a word , the red frame or the black/gold has caught her eye more than once. Said her K bike needs to go first.
