To bypass a relay, simply connect the two wires that are on either side of the relay. Relays are electronic switches used to control high-voltage and high-current circuits.
In certain situations, the relay might become faulty and cause the device it’s controlling to malfunction. To test if the relay is defective, you can use different methods such as testing for continuity or voltage drop. However, if you need to bypass the relay temporarily, you can do so by connecting the two wires that are on either side of the relay.
This will send an uninterrupted current flow to the device allowing it to function without the relay’s control. It’s important to note that bypassing a relay should only be a temporary solution as the relay is an important safety feature in most circuits.

- Power loss: Relays can also cause power loss, making it necessary to bypass them to keep the circuit running.
- To increase power: By bypassing a relay, you can eliminate the resistance it creates, resulting in more current flowing and an increase in power.
Benefits Of Bypassing The Relay
Bypassing a relay can have its advantages. Here are some benefits you may experience:
- Cost savings: By bypassing a relay instead of replacing it, you can save on replacement costs.
- Improved performance: Bypassing relays can result in improved performance since it eliminates the resistance the component creates.
- Enhanced durability: Bypassing the relay can help extend the life of the circuit by eliminating a problematic component.
Risks Involved In Bypassing The Relay
Although bypassing a relay can be beneficial in certain situations, it’s not always the best option. Here are some risks involved in bypassing a relay:
- Electrical hazards: Bypassing relays can potentially create electrical hazards since it eliminates the safety component’s protection.
- Damage to the circuit: In some cases, bypassing a relay can cause damage to the circuit if done incorrectly.
- Voiding warranties: If you bypass a relay and it ends up causing damage, it could void any warranties on your equipment.
It’s important to weigh the benefits and risks involved before choosing to bypass a relay. If you don’t have much experience with electrical circuits, it’s best to consult with a professional before attempting to bypass a relay.

How To Bypass A Relay Step-By-Step
When electrical relays malfunction or fail, they can prevent equipment from functioning correctly, sometimes halting operations altogether. To get equipment back up and running, you may need to bypass the relay. Bypassing a relay is not as complicated as it might seem, but it does require some safety precautions and knowledge of the process.
Here are the essential steps for bypassing a relay:
Precautions To Take Before Starting
Before attempting to bypass a relay, it is necessary to take safety precautions to prevent injury or damage to the equipment and people involved.
- Turn off the power source – cut off the power source that runs the equipment that you are handling.
- Disconnect the power supply – when dealing with electrical equipment, make sure that your power supply is disconnected from the device to avoid any shorts.
- Wear personal protective equipment – make sure to wear the appropriate personal protective equipment, such as gloves, goggles, and safety shoes.
Detailed Instructions For Bypassing A Relay
- Locate the relay – find the relay that you need to bypass. This may require some research on the equipment’s wiring diagram.
- Disconnect the wires – disconnect the wires from the relay by using a screwdriver, pliers, or wire cutters.
- Determine the relay function – figure out the relay’s function by examining the wiring diagram or the relay’s housing. This will help you identify the correct relay pins to bypass.
- Connect the wire – find the pin terminal that the wire was attached to in step 2. Connect that wire to the correct pin terminal on the device you are working with, using pliers or a screwdriver.
- Test the equipment – test the equipment to see if it is working correctly.
Troubleshooting Tips
If the equipment does not work correctly after bypassing the relay, some troubleshooting tips might help.
- Check the wiring connections – ensure the wiring connections are tight and corrosion-free.
- Inspect the relay – if the device still doesn’t work correctly, inspect the relay for damaged components.
- Replace the malfunctioning component – if the relay is irreparable, it’s time to replace it with a new one.
Bypassing a relay is not a complicated process, but it does require some safety precautions and knowledge of the process. With care and attention, you can safely bypass a relay and get your equipment up and running again.
Safety Precautions
Importance Of Safety When Dealing With Electricity
When bypassing a relay, it is crucial to prioritize safety measures to prevent deadly consequences.
- Electricity is a powerful force that can cause severe burns, electrical shock, and even death if not handled properly.
- Careless mistakes can result in short circuits, explosions, and fires.
Therefore, before attempting to bypass a relay, the following safety measures must be adhered to:
Detailed Safety Measures To Follow When Bypassing A Relay
- Turn off the power source before handling any electrical equipment to prevent any electrical contact or short circuits.
- Identify the wires and components accurately and create an updated circuit drawing to match the relay bypass requirements.
- Use a non-conductive and rated voltage tester to ensure that the electricity is off at the wiring terminal blocks before making any changes.
- Keep all electrical equipment properly grounded to mitigate the risk of electrical shock.
- Only certified and trained personnel should handle complex electrical equipment.
- Use personal protective equipment (ppe) like goggles, gloves, and safety boots.
- Cover all the neutral terminals and earth them to prevent accidents.
- Keep the work area dry, clean, and organized to prevent tripping.
- Never use a wet hand or any conductive material on electrical equipment.
Risk Of Injury
Even when strict safety protocols are in place, electrical work still poses significant risks.
