To safeguard facilities from disastrous power outages, more companies are now choosing to invest in generators as standby power source. However, just like any other mechanical machine out there, your generator can fail to start when you desperately need it to. To caution yourself from such incidents, you need to understand some of the common causes of this problems and what to do should it happen. Here are the top 5 reasons generators fail to start.
Wet stacking (oil leakage)
Diesel engines are designed to operate at certain temperatures. Running your generator for long periods of time at less than the recommended temperature can cause the engine to over fuel and leak, causing damage. An automatic load bank can prevent this problem from happening.
Good quality fuel is critical to your engine’s performance and endurance. Good fuel is important, but one that is often overlooked by many. This is true considering that fuel can become stale, stagnant and contain water. Contaminants can also build up on the bottom of the tank causing damage to the generator itself and contaminating new fuel. Always test and clean fuel inside the generator.
Low coolant levels
The most common cause of low coolant levels in a generator is either an external or internal leak. During your routine inspection of the unit, pay special attention to any visible puddles of coolant. Also, inspect oil for any signs of color change which is an indication that the coolant additives and seeping are drying up at the connection.
Presence of air in the fuel system
Another reason why your generator may fail to start is if there is air in the fuel system of the unit. This is a common problem with new generators. You can prevent this by periodically running the engine during your routine inspections.
Your generator will not start if the breaker trips after the auto transfer switch. In this case, check the status of the ATS to ensure that they have a power display showing the source availability and switch position.
