How to Bypass the Starter Relay | Factors of a Bad Starter Relay

How to Bypass the Starter Relay

The starting relay is a crucial part of your car’s electrical system. It is in charge of giving the starter electricity so that it can start the engine. Your car’s engine won’t start if your starter relay malfunctions. Some folks decided to get around the system to fix this. Numerous factors could make this a great or poor choice based on your circumstances. You will discover how to bypass the starter relay in this article.

How to Bypass the Starter Relay

Knowing how to bypass the starter relay in various situations is useful. If your car doesn’t start, the problem lies with the starter relay. You can restart your car by turning the relay off.

How to Bypass the Starter Relay

Bypassing the starting relay can be beneficial when you want to start the car without pressing the starter key. This is especially useful if your car has a gearbox and you don’t want to start the engine using the clutch foot switch or the brake pad needs to be fixed.

Last but not least, try this method to start your car if it is equipped with an electrical ignition switch and see if that helps.

Take these actions to get around your car’s starter relay:

  • Determining the trigger relay. The home or battery button is typically close by.
  • Connect the positive battery connection of the starter relay with a jumper wire.
  • If the ignition on your car is electronic, cut the cable that connects the starter relay to the ignition switch.
  • Disconnect the ignition button from the toggle clutch pedal if your car has a manual transmission.
  • Drive to the neighborhood store or repair shop after powering up.

You may always contact and wait for a truck driver to transport your car to a local petrol station or dealer for repair if all other alternatives have failed.

Common Factors of a Bad Starter Relay

If you are experiencing issues with the starting relay, you should identify the root cause and devise a solution. The following components may be contributing factors to starter relay issues:

A drained battery

Make sure your battery is charged enough first. Naturally, a drained battery can result in various electrical issues with your car, starting issues being one of them.

How to Bypass the Starter Relay

Find out if the starter relay is powered by the battery using a multimeter. Start by unplugging it from the vehicle. A multimeter should then measure the voltage between each wire and the ground. A drained battery must either be charged or replaced if the voltage is less than 12 volts.

Defective wiring

It could be necessary to replace the starter relay wiring if it appears damaged. You can check with a multimeter if there are no outward symptoms.

Defective wiring

Start by removing the vehicle’s battery. Then, using a multimeter, determine the conductivity between each wire and surface. If there is no continuity between any of the wires and the surface, it is probable that the wiring is faulty and has to be changed.

Defective solenoid

Defective solenoid

The solenoid physically turns the starting device on and off. Its malfunction may prevent it from correctly engaging the starting gear, which could lead to the relay failure. Similar to testing the cables, a multimeter can determine its resistance to determine if the starter relay solenoid is malfunctioning. The solenoid likely has to be changed if there is no continuity between the wires and the ground.

Damaged Coil

Damaged Coil

The coil is in charge of supplying the solenoid with power. It will need to be replaced if it is blown out. If you think the coil could be blown out, your companion in this situation is the multimeter once more. Test it for resistance; if there is none, it is already clogged and requires replacement.

The faulty starter circuit component

The faulty starter circuit component

The relay for the starter is in charge of powering the starter. Typically, turning the ignition key activates it. The car might not start if there is an issue. Therefore, it may be necessary to replace the relay itself if the starter relay cover or internal parts are damaged.

Frequently Asked Questions

Is the starting relay likely to malfunction frequently?

The starter relay rarely has issues. It seldom fails, but if it does, your car might not start, leaving you stranded. The starting relay, however, can stop working for some reasons. These can be damaged circuits, corroded circuits, bridged contacts, moist relays, or even obsolete relays.

Where on the car is the starting relay for the junction box?

You can identify the starting relay in the junction box by the sizable cable that emerges from the battery’s positive pole. In cars, they often live next to the battery in a box with a black lid.

How is a starting relay operated?

The ignition system, which includes the starter relay, was specially designed to transfer electricity from the car battery to the beginning solenoid. The starting solenoid and starter motor are switched by it.

How can I get around the fridge start relay?

You must disassemble the relay system, rewire the connections, strip the wires, and then tape the circuit to bypass the refrigerator’s start relay.


Due to the numerous risks involved, bypassing the starting relay should only be thought of as a last resort when there are no options other than getting your automobile to a professional immediately or in an emergency. Having things fixed by a pro is always the best option for this issue.

Expert Opinion

The starter relay may be gotten around in some ways. The most common method is by using a jumper wire. To do this, attach the jumper wire’s positive terminal on the battery to one end and the starting motor to the other. This way, electricity may go straight to the starting motor by bypassing the relay this way.

The starting relay can also be bypassed by removing it from the circuit. The starter button and the wiring connecting it to the battery can be cut off to achieve this. When the relay is removed, the starting motor will get power directly from the battery.
