My CAT 416E, with 178 hrs, yesterday suddenly refused to engage in REV. Drove her home in FW (work around farm, 600 meters): Was pending Cat Tech Srvie to do 1000 hr check and service anyway.
They checked underneath, checked fluids etc, and went to connect the Laptop to scan engine.
Now suddenly engine refuses to start. Starter does NOT engage, only far whirring sound suddenly, while machine started fine before.
Now, whole dashboard panel, shifter tower and electrical instrument cluster is opened and disassembled.
Team kept trying to get her to start, to no avail. I have a feeling is sort of a lock-out, moment they connected
Can anyone give me ideas?
