Hello, new user but have been reading here a while and finally had a problem. I have a 773G w/turbo ser# 519023576 . last fall this happened once and then never again until this week. I got the warning light on top right panel,the one that looks like an exclamation point. solid beep with flashing light then it shuts down. this only happens at mid to high rpm. low idle light does not come on. seat belt light is also flashing. I don`t see any type of wire on the belt and buckling it does nothing. I can`t find anything on the belt in the manual ,just the seat bar. any help or direction would be great . thanks ,Rich www.pattonacres.com
