The Top 5 Reasons Your Generator Won’t Start

Back up generators fail more times than they need to, facility and operation managers need to evaluate incident response procedures and plan for regular maintenance of equipment in which they are responsible for on site. We’ve compiled our Top 5 reasons that the can reduce your odds of failure.

Top Tip 1: Battery Maintenance

It is important that emergency power systems specify batteries that are assured with starting power. A common cause of battery performance failure is improper adjustment and operation of the battery charger often having a loose or dirty cable connections due to corrosion. The battery specified must meet the expectations of type, construction, chemistry and classification.

Top Tip 2: Wet Stacking

It is known fact that diesel engines are designed to operate at a certain temperature. Running a generator over a long period of time below optimum temperature can cause the engine to over fuel and leak in turn this could cause damage. An annual load test can prevent this if utilising the building load isn’t an option.

Top Tip 3: Fuel Contamination

It is critical to use good fuel quality, something which often becomes neglected. Did you know fuel can become stagnant, stale and contain excess water? Sediments can build up in the bottom of the tanks which in turn chances any damages to the generator, contaminating new fuel. Giving the generator a regular test and polish of fuel as part of a scheduled maintenance assures proper operation.

Top Tip 4: Incorrect Switches and Breakers Position

Scheduled maintenance routines and periodic off load runs, can sometimes mean that control panels are often neglected or checked – making sure that the output breaker is in the proper ready position. It is important to ensure that the generators control panel is in ‘auto’ and the ‘output’ breaker is in the on position.

Top Tip 5: Dirty Filters: Air, Fuel and Oil

Emissions systems require a strict filtration system adding to the side effects of making generators more susceptible to the environment they are in. Older generators typically suffer with high additive and low sulphur of today’s diesel fuel which adds to the clogging of fuel lines or filters by cleaning out a material in the system.
