Aggreko Generator not starting

An Aggreko generator that won't start or shuts down unexpectedly is often caused by fuel, oil, battery, or air filter issues. Common solutions include checking the fuel level and quality, verifying the oil level is sufficient, inspecting the battery and its connections, and cleaning or replacing the air filter and spark plug. For unexpected shutdowns, investigate the possibility of overloading or overheating, which can be caused by a blocked radiator or low coolant. 

 

Common causes and solutions

• Fuel problems: Check the fuel level and ensure the fuel is fresh. Stale fuel or a clogged fuel filter can cause issues.
• Oil problems: Low oil levels will trigger a low-oil shutdown. Check the oil level and add oil if needed. A clogged or dirty oil filter can also be a factor.
• Battery failure: A dead or weak battery can prevent the generator from starting. Check for loose connections and corrosion, and ensure the battery is charged.
• Air filter blockage: A clogged air filter restricts airflow, leading to a shutdown. Clean or replace the air filter to allow the engine to breathe properly.
• Spark plug issues: A faulty or dirty spark plug can cause it to fail to start or run poorly. Clean or replace the spark plug if it's old or damaged.
• Overloading: Running more equipment than the generator's capacity will cause it to shut down to prevent damage. Disconnect some equipment to reduce the load.
• Overheating: If the generator runs for a short time and then shuts off, it could be overheating. This can be caused by dust-clogged filters or a blocked radiator.
• Faulty sensors: Sensor malfunctions, such as a low oil pressure sensor, can cause the generator to shut down. 

 

Troubleshooting steps

1. Check the basics: Make sure the generator has enough fuel, the fuel valve is open, and there is enough oil.
2. Inspect the air filter: Clean or replace the air filter to ensure proper airflow.
3. Check the battery: Inspect the battery for loose connections or corrosion. Try jump-starting it if necessary.
4. Inspect the spark plug: Check for a worn or dirty spark plug and replace it if necessary.
5. Address overloads: Ensure you are not overloading the generator and check that the circuit breaker hasn't tripped.
6. Restart without load: Try restarting the generator with no equipment plugged into it to see if it runs properly.
7. Check for overheating: If the unit shuts off after running, inspect for a clogged radiator or low coolan
