Did this happen after a specific event? (e.g., jump-starting, heavy rain, or a long storage period) Do you have a multimeter available to test for continuity? fuse and wiring diagram for 6400 john deere tractor 2021

• Visual: inspect for melted fuses, burned connectors, frayed insulation, corroded terminals.
• Fuse test: with key off, visually inspect and test continuity with multimeter or swap with same-rated fuse.
• Voltage test: with key on, measure at fuse input and output; if input present and output absent, fuse or fuse holder open.
• Relay test: listen for click when energized; test coil resistance and continuity across contacts when coil energized (12 V).
• Ground test: verify chassis ground continuity to battery negative (<0.1–0.5 ohm ideally).
• Starter draw: if starter fuse repeatedly fails, check starter circuit for short or high current draw (professional).
• Intermittent faults: wiggle harnesses while monitoring for open circuits; inspect harness grommets at moving joints.
