How to Fix / Troubleshooting
Safety: Diesel spills are slip and fire hazards. Use absorbent material and avoid ignition sources.
- Check fuel level: Verify actual fuel level in the main and day tanks. Refill if low, ensuring vents are clear.
- Inspect for leaks: Examine flexible hoses, unions, and the base tank of the JCB generator for wet spots or diesel odor. Tighten fittings and replace damaged hoses.
- Fuel leak sensor: If the set has a bund leak sensor, inspect it for contamination or water. Clean or replace if it is falsely triggering.
- Level sender test: Access the fuel level sender on the tank. Check wiring and measure resistance or output signal while moving the float to confirm operation.
- Reset alarm: After correcting issues, clear E14 and test automatic start sequence.
