Understanding The Limitations Of Co Sensors
CO sensors play a critical role in ensuring the safety of operating a generator. Carbon monoxide (CO) is a silent killer, and the presence of this odorless and colorless gas can have severe consequences if not detected in time. However, it is important to understand that CO sensors also have their limitations.
We will dive deeper into the functionality of CO sensors and their impact on power output, providing you with a comprehensive understanding of how to bypass CO sensors on generators.
CO Sensor Functionality Explained
CO sensors are designed to detect and alert users to dangerous levels of carbon monoxide. These sensors work by measuring the concentration of CO gas in the air, typically expressed in parts per million (ppm). When the CO level exceeds a certain threshold, the sensor triggers an alarm to warn users of the potential danger.
The main component of a CO sensor is an electrochemical cell. This cell contains electrodes and an electrolyte solution, which react with the CO gas to produce an electrical current. The generated current is then measured by the sensor, allowing it to determine the CO concentration in the surrounding environment.
It’s important to note that CO sensors have a limited lifespan and may require regular calibration or replacement to ensure accurate readings. Over time, the electrodes in the electrochemical cell can degrade, leading to reduced sensor effectiveness. Additionally, external factors such as temperature and humidity can also affect the sensor’s performance.
Impact of CO Sensor on Power Output
While CO sensors are essential for safety purposes, they can sometimes interfere with the normal operation of a generator. In some cases, the presence of CO (even at safe levels) can trigger the generator’s shutdown mechanism as a precautionary measure. This is particularly true for generators that are specifically designed to be highly reactive to CO detection.
Understandably, this shutdown feature can be undesirable or inconvenient in certain situations, such as during outdoor events, construction sites, or emergency power situations. However, bypassing the CO sensor on a generator should only be considered after carefully assessing the associated risks and legal requirements.

Methods To Bypass Co Sensors on Generators
When it comes to generators, safety should always be a top priority. Carbon monoxide (CO) sensors play a crucial role in detecting the presence of this deadly gas and shutting down the generator to prevent any harm. However, there may be certain situations where bypassing these sensors becomes necessary. In this section, we will explore two methods to bypass CO sensors – manual bypassing and using aftermarket bypass kits.
Manual Bypassing
If you find yourself in a situation where you need to manually bypass the CO sensor on your generator, follow these simple steps:
Step-by-Step Guide to Manually Bypass the CO Sensor
Step 1: Locate the CO Sensor
The CO sensor is usually positioned near the control panel or exhaust system of your generator. Check your generator’s manual for the exact location and wiring diagram to ensure you are working on the correct component. Identifying the sensor correctly is crucial before proceeding with any modifications.
Step 2: Turn Off and Unplug the Generator
Before making any changes, turn off the generator completely and unplug it from any power source. This step is essential for safety, as it prevents the risk of electric shock. Allow the generator to sit for a few minutes to ensure that any residual electricity is discharged before proceeding to the next step.
Step 3: Remove the CO Sensor
Using a screwdriver, carefully remove the screws or clips securing the CO sensor in place. Gently detach the sensor without pulling or damaging the wiring. If necessary, take a picture of the wiring configuration before proceeding so you can reference it later.
Step 4: Identify the Wiring Type (NC or NO Circuit)
To determine how the sensor controls the generator’s shut-off mechanism, you need to check whether it operates as a Normally Closed (NC) or Normally Open (NO) circuit. Set a multimeter to continuity mode (Ω or beep mode) and place the probes on the two sensor wires.
If the multimeter beeps or shows continuity, the sensor is using an NC circuit. If there is no beep or continuity, it is an NO circuit. You can further confirm by exposing the sensor to a small amount of CO gas, such as car exhaust. If the circuit breaks when exposed, it is an NC circuit. If the circuit closes when exposed, it is an NO circuit.
Step 5: Bypass the CO Sensor Wiring
Once the wiring type is identified, proceed with the bypass. If the sensor operates on an NC circuit, the circuit must remain closed for the generator to function properly. To bypass it, connect the two sensor wires together by twisting them securely or using a jumper wire.
Ensure the connection is firm, then insulate it with electrical tape or heat shrink tubing to prevent short circuits. If the sensor uses an NO circuit, the circuit must remain open. To bypass it, leave the two sensor wires disconnected and insulate each one individually with electrical tape to prevent accidental contact.
Step 6: Secure the Wiring and Reassemble the Generator
Double-check that all connections are secure and properly insulated. If any panels or covers were removed during the process, reattach them to ensure the generator is properly reassembled. This will protect the internal components and wiring from external damage.
Step 7: Test the Generator
Reconnect the generator to its power source and start it. Observe its operation to confirm that it runs without shutting off due to CO sensor interference. If the generator functions normally, the bypass has been successful. However, if the generator still shuts off, double-check your wiring connections and ensure that the bypass was performed correctly.
