What causes the error code on my John Deere 668b SPN 94 FMI 3 fuel rail pressure voltage out of range high?
"Out of range high" or "Voltage above normal, shorted to high source" implies the fuel rail pressure sensor signal wire is shorted to the sensor 5V or other voltage source or the sensor itself has failed.
Likely there is a short in the harness from abrasion or rodent damage but not the only cause. You don't want to start pulling on the harness and inadvertently open the short or the problem will likely reoccur at a most inopportune time.
You'll want to carefully disconnect the sensor and the opposite end of the harness and perform a continuity test between sensor 5V and the sensor signal wire. If no continuity, the harness is not shorted. Then you'll need to do further testing to determine if the problem is the sensor or the ECU.
Wont start new battery new voltage regulator no spark to plugs
Bad coil, or one of the safety switches are shutting the coil down. To test this before replacing the coil. Disconnect the small wire to the coil that is mounted with an electrical clip. This is the wire that kills the coil by grounding it. Try to start it now but be aware that you just disabled your off switch. If it starts you will only be able to turn it of by choking the carb, grounding your spark plug wire or pulling the plug wire off. Good luck.
What hydro fluid does a john deere 333d skid steer use
333D uses a variety of oil for the hydraulic system. Primarily 10W-30 Torq-Guard Supreme or 10W-30 Plus 50 IIEXCEPT: If your machine was equipped with the cold start package, it will use either Plus 50 II 0W-40 or Hydrau XR (Hydrau XR can be added to Plus 50 II 0W-40 in any ratio, ie. topping off 0W-40 with Hydrau XR is okay)
