Controller displays E14, generator will not start or shuts down during crank cycle

Safety first: Place the controller in OFF, open the main breaker, and allow the unit to rest between crank attempts to avoid overheating the starter.

• Step 1 – Review event log: Use the Multiquip controller menu to confirm that E14 is due to repeated unsuccessful crank attempts.
• Step 2 – Check basic starting conditions: Verify fuel level, battery voltage, and that the emergency stop is reset. Replace a dirty air filter.
• Step 3 – Inspect glow plug circuit (diesel): Check the glow plug fuse and relay. Measure voltage at the glow plug bus bar during preheat. If no voltage, replace the relay or repair wiring. Replace failed glow plugs if they show open circuit on a resistance test.
• Step 4 – Check for fuel at injectors: Loosen one injector line nut slightly and crank briefly (observe safety and fire precautions). Fuel should pulse from the fitting. If not, suspect a fuel pump or solenoid issue.
• Step 5 – Clear code and attempt start: After addressing fuel and starting system issues, clear E14 and attempt a manual start. If the engine still fails to fire, further diagnosis of compression and timing is required by a technician.
