John Deere PE4045TF285 — full specs, parts & maintenance.
| Code | Meaning |
|---|---|
| Sd Gen L1 <V | Shutdown Generator Line 1 Voltage Low |
| Sd Gen L2 <V | Shutdown Generator Line 2 Voltage Low |
| Sd Gen L3 <V | Shutdown Generator Line 3 Voltage Low |
| Symptom | Remedy |
|---|---|
| Oil pressure value does not read 5 psi (34 kPa) within five seconds | Visually inspect the engine for oil leaks. If the oil level is good, restart the unit and verify the loss of oil pressure. Shut the engine down immediately if the oil pressure value does not read 5 psi (34 kPa) within five seconds. Check the oil sender. |
| LOW COOLANT LEVEL | Allow the engine to cool. Check the coolant level in the radiator. To access the radiator cap, you must remove the access panel from the top of the enclosure directly above the radiator. Add coolant until it is 3/4 in. (1.9 cm) below the filler neck. Secure the radiator cap back into its original position. Inspect coolant hoses, engine block and water pump for visible leaks. Check the engine oil to verify no coolant has mixed with it (oil will appear milky if coolant is present). Consult the engine operator’s manual for additional information. |
| HIGH COOLANT TEMPERATURE | Check the coolant level in the overflow jug. Restart the engine and read the coolant temperature to verify a high coolant temperature shutdown. Stop the engine immediately if the coolant temperature is 230°F (110°C) or more. Allow the engine to cool. Add coolant to the overflow jug if it is low and then check the level of coolant in the radiator. To access the radiator cap, you must remove the access panel from the top of the enclosure directly above the radiator. Add coolant until it is 3/4 in. (1.9 cm) below the filler neck. Secure the radiator cap back into its original position. Check the radiator shroud and ducting for blockage and remove any foreign matter. Inspect coolant hoses, engine block and water pump for visible leaks. Check the tension of the serpentine drive belt for the water pump. If no other problems are found, remove the load on the generator and restart the engine. Check the coolant temperature and shut the engine down immediately if it starts to overheat. Consult the engine operator’s manual for additional information on engine overheating. |
| OVERCRANK SHUTDOWN | Check the fuel level in the tank. Check for proper operation of the fuel pump. Check the air filter for blockage. If the engine will not start, consult the engine operator’s manual for additional information on trouble-shooting starting problems. |
| OVERSPEED OR UNDERSPEED SHUTDOWN | Disconnect all loads and restart the generator. Read the frequency (Hz) on the LCD display. With no loads on the generator, the frequency should read 60.0 Hz. If the frequency is above or below 60.0 Hz, the engine speed will have to be adjusted. Refer to the engine operator’s manual for throttle adjustments on mechanical governed units and see the electronic governor manual for electronically controlled units. |
