John Deere 4310 Clutch Potentiometer Testing and Calibration ePower Reverser

This is a hands-on diagnostic session for a specific, often-misunderstood fault on the 4310's ePower Reverser: a clutch acting like it's slipping or stopping on its own. The creator back-feeds the clutch potentiometer with a sewing needle, reads actual voltage values (0.9V low, 4.2-4.8V high), shows a bad switch fluctuating in real time, and walks through full recalibration. Best for owners troubleshooting this exact symptom.
