A fuse panel diagram is a schematic map that links each fuse or breaker position to:
Key interpretation steps:
| Fuse Position | Amperage (A) | Circuit / Component Protected | | :--- | :--- | :--- | | | 200A (Mega) | Alternator to battery main feed | | F101 | 60A (J-Case) | Hydraulic cooling fan motor (Variable speed) | | F102 | 40A (J-Case) | Glow plug controller (Pre-heat for cold starts) | | F103 | 30A (J-Case) | Starter solenoid (Key crank signal) | | F104 | 30A | Fuel lift pump & fuel system heater (Tier 4) | | F105 | 30A | DEF (Diesel Exhaust Fluid) Dosing control unit | | F106 | 50A | Regen (Regeneration) fan motor & burner (DPF cleaning system) | | F107 | 25A | Engine cooling fan (PWM controlled – if not hydraulic) | | F108 | 10A | Exhaust gas recirculation (EGR) valve actuator | | F109 | 15A | Engine stop solenoid (Fuel shutoff) | John Deere 333g Fuse Panel Diagram
