    I have a warning light flashing and beeping on my 277C. It only does it when moving forward or backward and stops while sitting still. It started when I was back and forth loading dumptrucks with topsoil the other day. The manual is no help just says shut it off and contact dealer. Question is, could a broken window or broken idler wheel cause this alarm to go off. Left side bottom window got busted out by a tree limb last week and I noticed a rear inner idler wheel on both sides was broken and haven't had a chance to fix either. I had an idler wheel break a few weeks ago but it did not set off alarm. Also all fluids are good, not running hot... Thanks in advance.:confused:

    Sounds to me like speed sensor wire is damaged this is the wire that follows the hydraulic lines out to the drive motor in the track .

    If it's a yellow light with a "!" flashing, it's the speed sensor, our went out earlier this year, beeped and flashed when you drive it, but goes away when the tracks stay still.
    An no, there's no fuse to kill it, I lost a day of work due to that damn sensor.

    I'll check it out. I hate to say it but it hasn't slowed me down any. No time to waste. I figured it wasn't too serious because it'll do it for a few minutes then may go off for 2 hours before it does it again.

    I ordered one today $257. Plus the 2 idler wheels at $120 a piece. Still needs to look at those wires on speed sensor.

    Finally took it to the dealer, the alert stays on now anytime you move. They confirmed it is speed sensor on left side, is it really tough to change it out or should I let them do it? They estimate $750-800 total to do it.

    Trace the wires, ours let go just at the frame/drive motor area, it was still a royal PITA to change.

    I just left it for them to fix, I guess the $800 is worth me not having to do it and go through the frustration, and it'll be done tomorrow afternoon.

    On my 2014 259D I had the same light come on. The tech ran a computer scan and said 2 different wheel speed sensors threw codes. They only did it for about 5 min and havent done it since. They said to see if it happens again.
