What is an ignition relay switch?
The ignition relay is one of the most important electronic relays found on modern vehicles. When the key is turned to the on position the relay is switched on and power is directed to the vehicle’s ignition and fuel system components, notably the fuel pump and ignition coils.
How is the ignition switch connected to the starter relay?
The opposite side would be connected to the starter solenoid. I connected the jumpers to the relay. Then Tucked it up out of the way. I think I need some velcro or something here to keep it in place. The Hot wire from the battery went through the firewall where the hood latch cable feeds through. I added a fuse block just in case.
How to bypass ignition switch for starter solenoid?
This is what I did to bypass the ignition switch for the starter solenoid, and just run the relay coil from the ignition switch. I made 3 12″ long jumpers. Then I had to check to see which side of the relay the Ignition switch was on. The opposite side would be connected to the starter solenoid. I connected the jumpers to the relay.
Why is my Toyota starter relay not working?
I think it was somewhere around 7-8v at the solenoid. This meant that too much current was going through the ignition switch, and it was dropping too much voltage for the solenoid to work. All this does is use the ignition switch to power the relay, and not both the relay and the solenoid.
When do you know something is wrong with the ignition relay?
If nothing happens on your dashboard when you turn the key in the ignition lock, and you are sure that the car battery is charged – there is a big risk that something is wrong with the ignition relay. These issues need to be solved as soon as possible. Otherwise, you will be forced to travel without your car.
What do you need to know about a starter relay?
What is a Starter Relay? A starter relay is a small, electrical device found in the starting circuit of high-current motors. The relay is essentially a remote switch that controls a high-current circuit. In motor vehicles, a starter relay uses the small ignition switch current to close the much heavy-duty starter circuit.
Can a bad ignition switch cause a starter relay to fail?
Although it’s unlikely that you’ll ever experience a problem with the starter relay, it is prone to mechanical failure and will need to be replaced by a professional mechanic if it wears out. Most of today’s modern cars and trucks have an electronic ignition switch that is activated by remote key.

How does the ignition relay work on a car?
The ignition relay is basically an electrical device that works as a switch for the power to the ignition system and the fuel system of your vehicle. The ignition relay is activated as soon as your turn on the ignition of your vehicle with the key.
