thanks for the info . the glow plugs were dead . i've ordered new plugs in addition to the controller. now i'd like to pick your brain on other issues; first ,were you able to find the service manual on-line? second, the shuttle shift has always been very stiff and in fact will freeze in cold weather so obviously has moisture in it. i've tried lubricating the cable to no avail. the dealer shrugs his shoulders. Other the the starting ,shifting, split transmissioncase,broken spur gears in the front drive,and broken backhoe subframe its works fine . thanks again for your halp
