A Detailed Guide On How To Bypass Low Oil Sensor On Generator
Many devices are now equipped with a system for shutting down the engine in the generator in case oil pressure drops are at a minimum level. Because of this, the construction process may abruptly stop, for example.
In this article, you can find the answer to the question: “how to bypass low oil sensor on generator” with detailed steps, as well as the causes of low oil pressure.
What is an oil sensor on the generator?
The oil sensor is a unique sensor that alerts the generator system if the fluid level is insufficient, which in turn causes the generator to stop by shutting down the engine inside.
Why oil pressure is low?
Low oil pressure is often the cause of a generator problem you won’t even realize immediately until you specifically check. It is very important to know the causes of this problem.
Apparent low pressure
You will be able to identify the problem of low oil pressure in a diesel generator the best, as it is easiest to understand the amount of voltage on them using a pressure gauge. Low pressure in the generator itself will, of course, affect the oil.
Low amount of oil
Not enough oil can also cause low oil pressure. If you have worn oil plugs or seals, the oil will leak through them, resulting in the generator engine itself getting less than it needs.
Defective oil pressure gauge
A defective gauge unfortunately will not even let you know that you have low oil pressure. You need to check all sensors: oil sensor pressure and oil level sensor. Also, be sure to check the operation of the oil pressure warning light.
The more worn and old parts of the generator engine, for example, bearings, the more problems will be associated with oil, since firstly the amount of use will increase, and vice versa, the pressure will decrease.
A clogged filter is one of the biggest hindrances to the operation of oil, which may prevent the oil from even getting into the engine. Most often, the filter becomes clogged from contamination, a breakdown inside the bypass valve system, and too much oil consumption.
A worn-out oil pump directly spoils the operation of the oil. This can be seen if the oil level is in the middle condition in terms of quantity; however, the generator engine continues to run loudly. In this case, only a complete replacement of the pump can help.
Advantages and disadvantages to bypass low oil sensor on generator
The main advantage of bypassing the low oil sensor is of course the fact that you will be able to continue using the generator even when the oil level is low. This is especially good if you need to continuously use the generator, or you can top up the generator in case the sensor starts alerting you to a critically low oil level.
However, you should also not forget about the disadvantages of bypassing the low oil sensor, since the generator will degrade its performance during continuous operation. It leads to a breakdown in the generator system, that is, the engine. Many companies will void the warranty on their generators if owners use the low oil sensor bypass.
- Perform bypass outdoors
- Wear safety clothes: respirator, glasses, and gloves
- Have contact with a specialist
- Don’t touch the generator when it is activated and hot.
Instructions on bypassing low oil sensor
If for you, the disadvantages of bypassing the low oil sensor still become less important than the advantages, then you can read the instructions below.
The first step in bypassing the low oil sensor is to locate the yellow wire on your alternator. Most often, its location is near the oil fill cap. If you’re not sure where the yellow wire is, do some research on your alternator model.
There is a green wire connector on the yellow wire, which will also be needed to bypass the low oil sensor. With it, you need to disconnect the generator wiring.
Now you need to activate the generator, it should run within 30 minutes, and wait until the low oil sensor itself starts to separate from the bottom of the engine.
Can you disconnect the oil pressure sensor?
Actually, yes, it is possible to completely disconnect the oil pressure sensor from your generator. However, this may lead to not very good consequences, such as a breakdown in the operation of the generator engine and not the fact that you can connect the sensor back.
How do you test an oil sensor on a generator?
With a multimeter, you can measure the performance of your sensor, you can also use the switch status of your generator’s engine. However, it is better if you have problems with the sensor, immediately contact a specialist and not try to solve this problem yourself.
How do you bypass a generator oil pressure sensor?
Using a complete disconnect of the wiring and waiting until the oil sensor begins peeling off from the generator’s bottom.
Again, it is not certain that you will be able to use the sensor after that, so it is best to take the generator to a specialist to install a new sensor, as repairs to the generator and its engine can cost you dearly due to improper use of oil.
How do you bypass the low oil switch on a Honda engine?
The process is the same as with the generators of other machines. You need to turn off the engine first, then remove the clamp and wiring, disconnect wires that belong to the oil sensor, and put back the wiring that is not connected to the oil sensor.
Can a generator start with a low oil?
If the oil level is critically low, the generator engine will not be able to start in any way, since manufacturers have specially created such an engine health protection system to avoid premature wear of the generator engine.
We hope that after reading this article, the question is: “how to bypass low oil sensor on generator?” will no longer remain unanswered for you since now you are familiar with the detailed steps and even security measures to successfully bypass the low oil sensor.
Moreover, now you understand the reasons for the penetration of low oil pressure.
