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.
