Top Reasons Why Your Industrial Generator Won’t Start

Top Reasons Why Your Industrial Generator Won’t Start

An industrial generator is a very important source of generating electrical energy in an emergency period. We are using in our company or big shops business like the pacific malls. This specific case of the engine generator. In the current prospectus, we can mostly see different types of generators using diesel generators but some types are adapted to other liquid fuels or natural gases. The power is the proper size to control the load of power shortages. Sizing is complicated by the characteristics of modern electronics, especially nonlinear weights.

The electrical loads are characteristics such as kW, kVA, var, harmonic content, surge currents and non-linear loads. The expected duty is such as (emergency, prime or continuous power) well as the environmental conditions that must be considered. Most of the industrial generator is manufacturer offer software that will perform the complicated sizing calculations by inputting the simply site and connected electrical load.

When we try to But some time generators raise the problem to start. When we can at least one hope the pieces of machinery are not 100% reliable. Here we explore very few common reasons why your generator starts. And how to reduce the risk of generator failure. Despite each passing year, our society relies on an unlimited supply of electricity that keeps them growing. The availability of this continuous power, which helps your business maintain operations, avoids the loss of revenue. And lastly protecting its bottom line, more companies are choosing to invest in additional power systems for facilities protected from disruption.

Reasons To Industrial Generator are Fails In Start

Generator Battery Failure

This is one of the very common reasons a generator will not start is due to battery failures. All batteries have a limited life to generate output current and there are the most top reasons to damage your battery life:-

Internal Resistant

we know the electric current flow is face resistance when it passing through a circuit and batteries have also an internal resistant on their own. this resistance could be due to temperatures, electrolyte, size and etc. when the resistant is increases then after the certain battery stops to working. Alkaline batteries have high internal resistance, while lead-acid batteries have low internal resistance.

Electrical Leakage Industrial Generate

All batteries are tended to lose electric current when it is not in use. This is called battery self-charge. In the primary battery, it can lose up to minimum power. The rechargeable battery is lost when it is fully charged and then the charging is reduced. There are some factors that are affected by electrical leakage, are affected by electrical leakage, some factors are manufacturing practices, operating temperature, aging, charge/discharge cycle, etc.


Included with humans the everything fades away with time and so do batteries. as time progresses, the internal resistance of batteries is increasing. This is more for recharge as the battery becomes hot during charging. This in internal resistance leads to their eventual failure.

High Cut-Off Voltage

In the case rechargeable battery, manufacture prescribes a cut-off voltage for the batteries, the voltage which supports to have discharged is its cut off voltage. In fact, there is still some power left, but this limit for recharging ensures a longer battery life. Many portable devices there are shut down due to a lack of electricity before they can actually do so.

Batteries Improper Storage

From time to time, the battery requires proper and careful care. Premature battery failure is a very important cause of battery failure when not in use. You should be careful to read the manufacturer’s instructions about disconnecting the battery. When it is not in use as well as how to store it. the battery failure can also occur due to the charger breaker it will also open inoperable, usually by a fault within the battery charger breaker being open your incomparable usually by fault within the battery charger you can easily solve your problem with the help of our blog and the charger supply circuit breaker is in the correct position.

Low Coolant Level In The

Industrial Generator without the radiator coolant, an engine would soon overheat and leads to mechanical breakdown and engine failures. it’s very important to check the coolant levels on a regular basis by visually checking if there are any puddles of the coolant. The coolant color is de[pend on the manufacturer although it is generally in red-colored.

An internally plugged radiator core also leads to a low coolant level shutdown. When the generator operates under load. Then the thermostat opens fully when the engine reaches optimum operating temperature. This means that the radiator will not be allowed to flow the proper amount through the core. Because the coolant has to go somewhere else. It can escape through the overflow line.

When the engine cools, the thermostat is close to the auto, the level drops, and the low coolant in our generator turns off. Because this only happens when the industrial generator reaches the optimal running temperature and is under load.

  1. For allowing the premature opening, the Thermostat stuck in the open position or malfunctions.
  2. Slush freeze or frozen coolant is the result of insufficient antifreeze in the system of mixing poor antifreeze water.
  3. If the cooling system is in Dirt and scale of sludge.
  4. plugged to the radiator core.
  5. Combustion gases are entering the cooling system and displacing the coolant causing it to overflow.
  6. Sized fill line or Improper routed.
  7. Excessive air intake temperature.
  8. Fill line can handle when more water can be entered into the area above the baffle.
  9. The coolant in the radiator with a thermostat is sealed and sealed and sealed properly.
  10. A leak creates a water barrier through the core.

Bad Fuel Mix

When we can start an industrial generator, fuel starts to burn and release energy for the start. But If the generator fuel tank mix with unnecessary liquids, who will not start the procedure to release energy for starting your generator. In these terms, the water mixing process is already harming to fuel burn process.

  1. There are the many reasons to your generator will not start it is linked to some way to fuel. Bad fuel can mix occur in several ways:-
  2. When your generator fuel is running out the engine and receiving to air but no fuel.
  3. The intake of air is halt. This means that there is fuel in your generator but the air is almost absent.
  4. The fuel systems might be supplying too much and too little fuel to the mix. Consequently, combustion with generator engines is not worked properly.
  5. Fuel impurities If water is a presence in the fuel tank, which is the cause of the fuel, it does not burn and then creates a problem to start the generator. Often this happens when fuel is standing in tanks for a long time.

Controls Not In Auto

Our generator has a control panel, which can control all the activities of your generator such as voltage up and down, etc. The control panel is automatically under control for all processes. If you can see your control panel display showing “not in the auto”, it is a result of human error. Usually due to the main control switch being left in the off / reset position. When it is in this state, the generator cannot start in a power outage event.

So, you check the control panel of your generator on a regular basis to make sure to “not in the auto” is not showing on display. There are plenty of any other faults which is display upon the control panel that can result in your generator is not starting.

Testing Of All The Switches

If you see problems and problems with any of the switches (power switch, start switch, or safety switch), try to test each one for the shortfall. The best way to do this is by utilizing a multimeter test. This test is helping you to determine why the switches working not properly.

Checking Spark Plugs

If the generator is may not be working properly and correctly or would not be the start,  then your first priority and troubleshooting technique is to analyze the generator spark plug. Be sure to spark the plug as it attaches securely or not as it can easily loosen. Also looking for a sign of wear and tear on the spark plug as a fixed issue may as simply require replacement.

When you see a more serious sign of damage, including a plug immersed in oil, you have noticed more serious issues, then immediately contact your energy resources resource. They are helping to solve your generator issues.

Test Ignition Coils

While the generator is running, The ignition coils are sending the power to the generator spark plug. Check After the spark plug, test the ignition coil for deficiency. If it is part of the issue, that it is typically inexpensive and easy to fix a generator.

May Need Replacement Of Air Filter

While the generator is running, the engine needs to air for the combustion of the fuel. then check the air filter and clean if they are dirty. The air filter and choke is working together and start to motor check the position of choke if it does not need to change or replace the Air filters. Not having the choke in the proper position can prevent the engine from starting from the cold weather.

Generator Troubles With The Carburetor

When we have the need for the generator but we can not use it on a daily basis. For this reason, it is common to cause problems with the carburetor because the machine sits for a while before using it. In this situation, the generator cannot start because the carburetor is filling with the remaining fuel. Because when fuel is exempt into the generator tank, over time some elements evaporate and condense with others and prevent the generator from starting.
