I posted this writeup on another part of the forum and then thought this would be the place for it, so here is the procedure Chris Cupp at LHR had me perform to diagnose my cut motor errors:
He had me spin the flex cable and check that the value on the RPM sensor changed (0,7, then up once). It did, so next he had me remove the cover, then the RPM Sensor (one small screw) and with a strong light turn the flex shaft again(with power off the machine) and check for a small projection on the shaft that is the magnet the rpm sensor reads. Mine looked more like a weld splatter and had no projection at all........ verdict - new cut motor on its way. If the magnet was there, then it would have probably been the RPM Sensor.
Hope this helps somebody cut down on thier phone time and maybe speed up the service process with the fine folks down in Texas.
