John Deere 4200, 4300, 4400 Common Problems This Manual Covers
John Deere 4300 engine cranks but fails to start intermittently or only starts after bypassing the solenoid. p. 117
Test the fuel shutoff solenoid voltage on page 124. Pull-in voltage should read 6.8 VDC and hold voltage 3.0 VDC. Measure resistance from pin B to C. If it exceeds 12.0 ohms, replace the fuel shutoff solenoid.
Manual Section: Section 4 - ELECTRICALCorroded electrical relays fail unexpectedly and cause intermittent operation or complete loss of power during field use. p. 117
Remove the suspect relays and inspect the terminals for corrosion. Measure the relay coil resistance per the Electrical section's relay test; it should read about 80 ohms. Replace the relay and clean the harness connector if continuity is wrong or resistance falls out of spec.
Manual Section: Section 4 - ELECTRICALParking brake light stays illuminated on the dash or only clears when the lever is physically moved. p. 117
Check the park brake switch plunger travel for proper engagement. Adjust the switch mounting bracket per the Electrical section's park brake switch test so the plunger sits about 3 mm (1/8 in.) from bottoming out. Verify switch continuity, and if it reads wrong in any lever position, swap the switch.
Manual Section: Section 4 - ELECTRICALEngine misfires, surges, or runs poorly with excessive exhaust smoke and high fuel consumption under load.
Pull the fuel injectors and bench-test them. Confirm the nozzle opening pressure reaches 19600 kPa, as specified on page 40. Inspect the fuel filter and lines for air intrusion, then work through the troubleshooting chart for poor exhaust color.
Manual Section: Diesel Engine Troubleshooting ChartFrequently Asked Questions
What causes the John Deere 4200 temperature gauge or fuel gauge to stop working?
A dead fuel gauge usually traces to a faulty control panel, a break in the 353 Org, 050L, or 050A Blk wiring, or a fuel sensor that no longer delivers its 5 to 95 ohm variable resistance. A frozen temperature gauge points to the control panel, the 359 Wht wiring, or a coolant temperature sensor reading outside its 40 to 700 ohm range.
How do I troubleshoot relay problems on a John Deere 4200, 4300, or 4400?
Start by checking terminal continuity with an ohmmeter or continuity tester. Jumper the battery positive (+) terminal to relay terminal C (85), and relay terminal D (86) to the battery negative (–) terminal. Replace the relay if continuity is not correct, or if resistance between terminals C (85) and D (86) is not about 80 ohms.
What are the replacement specifications for Relays?
Per the manual, a good relay shows continuity between terminals A (30) and E (87), plus roughly 80 ohms of resistance between terminals C (85) and D (86). Any relay that fails to meet either the continuity or the resistance spec during testing should be replaced.
What format is this John Deere 4200, 4300, 4400 manual in?
Immediate download of the complete 742-page searchable Technical Manual. Open it on any device: laptop at your desk or phone in the field.
Can I print specific sections of this John Deere 4200, 4300, 4400 manual?
Absolutely. No DRM or copy protection. Print the whole manual or just the pages you need. Any home or office printer works.
Are electrical wiring diagrams included in this John Deere 4200, 4300, 4400?
Included. The John Deere 4200, 4300, 4400 Technical Manual covers complete wiring harness diagrams, electrical circuits, and connector pinouts.
